Ember Coffee Co.

Here's something you probably weren't expecting to hear from a coffee roaster: that first cup you're reaching for the moment your eyes open? It might not be doing you any favors. The best time to drink coffee isn't necessarily when you want it most, it's when your body can actually use it. We love coffee (obviously), but we also want you to get the most out of every cup. That means understanding how caffeine interacts with your body's natural rhythms. Let's dig into what the research actually shows about when to drink coffee for energy, performance, and better sleep. Why Your Wake-Up Cup Might Be Too Early Your body has a built-in alertness system, and it doesn't need coffee to get started. Within 30-45 minutes of waking, your cortisol levels spike in what scientists call the Cortisol Awakening Response. This natural hormone surge helps clear the sleepiness from your system and gets you ready for the day. Here's the thing: drinking coffee during this cortisol spike is a bit like shouting into a megaphone that's already at full volume. You're adding stimulation when your body is already providing it. According to Cleveland Clinic research, this can reduce the effectiveness of both the cortisol and the caffeine. The result? You might feel jittery in the morning but crash harder in the afternoon, exactly when you need energy most. The 90-Minute Rule: When to Have Your First Cup So when should you actually drink that first cup? The science points to waiting about 90-120 minutes after waking. Dr. Andrew Huberman, a neuroscientist at Stanford, popularized this approach based on how adenosine (the chemical that makes you feel sleepy) and cortisol interact. When you first wake up, your body is naturally clearing adenosine. Hitting it with caffeine before that process completes can leave residual adenosine in your system, setting you up for that afternoon crash. For most people waking between 6:30 and 7:30 a.m., the optimal window for that first cup falls between 9:30 and 11:00 a.m. Does this mean you'll feel terrible if you drink coffee at 7 a.m.? Not necessarily. If you're a habitual coffee drinker, research from PMC/NIH shows your body has likely adapted to some of these effects. But if you've ever wondered why your morning coffee doesn't seem to "work" like it used to, timing might be the variable worth changing. The Best Time to Drink Coffee Before a Workout If you're using coffee as a pre-workout boost, timing matters even more. The research here is pretty clear. According to the International Society of Sports Nutrition, caffeine reaches peak concentration in your blood about 45 minutes after you drink it. For optimal exercise performance, you'll want that peak to coincide with your workout, which means drinking coffee 45-60 minutes before you exercise. What kind of benefits are we talking about? Improved muscular endurance Strength and power output increased by up to 11% Better aerobic performance (the most consistent benefit in studies) Reduced perception of effort and fatigue The effective dose in most studies is 3-6 mg of caffeine per kilogram of body weight. For most adults, that's roughly 1-2 cups of coffee. One more thing: drinking coffee on an empty stomach means faster absorption. If you're trying to maximize that pre-workout effect, skip the breakfast beforehand. But if coffee on an empty stomach bothers you, eating something won't eliminate the benefits, it'll just delay the peak by about 20-30 minutes. When to Stop Drinking Coffee (The Sleep Question) This is where a lot of people get it wrong. Caffeine has a half-life of about 5-6 hours on average, meaning half of what you consumed is still in your system that many hours later. But here's the catch: that's an average. For some people, the half-life is closer to 10 hours. A study published in the Journal of Clinical Sleep Medicine found that caffeine consumed even 6 hours before bedtime reduced total sleep time by more than an hour. And participants often didn't realize their sleep quality had suffered. Recommended Cutoff Times Your sensitivity to caffeine determines when you should have your last cup: people with normal sensitivity should stop 6-8 hours before bed, caffeine-sensitive individuals need 8-10 hours, and slow metabolizers require 10-12 hours between their last cup and bedtime. For a 10 p.m. bedtime, that means your last cup should probably be sometime between noon and 2 p.m., earlier if you know caffeine hits you hard.How do you know if you're a slow metabolizer? About half the population carries genetic variants (in the CYP1A2 gene) that slow caffeine processing. If you've ever noticed that afternoon coffee keeps you up at night while your friend sleeps fine, genetics might be the reason. How Food Changes Coffee Absorption What you eat (or don't eat) affects how quickly caffeine hits your system. On an empty stomach: Fastest absorption. Peak caffeine levels in about 45 minutes. With food: Slower absorption. Peak delayed by 20-30 minutes, but the total amount absorbed stays the same. The type of food you eat with coffee affects caffeine absorption: high-fat foods significantly delay the peak, protein-rich foods moderately delay it, high-fiber foods cause a slight delay, and simple carbs have minimal effect. There's no "right" answer here, it depends on what you're going for. Want a quick energy boost? Drink it without food. Want sustained, gradual energy? Have it with breakfast. One interesting note from the NCBI pharmacology research: grapefruit juice can decrease caffeine clearance by 23% and extend its half-life by 31%. So if you're having grapefruit with your morning coffee, you might want to account for that. The Afternoon Slump: To Coffee or Not to Coffee That 2-3 p.m. energy crash is real, and it's tempting to reach for another cup. Whether you should depends on your sleep schedule. If your cutoff time allows it, afternoon coffee can genuinely help. Research from the Sleep Foundation shows that 88% of people who regularly consume afternoon caffeine report at least one sleep problem, but that doesn't mean you need to skip it entirely. It means you need to time it right. A better approach for many people: if you're going to have afternoon coffee, make it earlier (1-2 p.m. rather than 3-4 p.m.) and consider a smaller serving. You'll still get a boost without as much impact on your sleep. Or try this: instead of fighting the slump with caffeine, address the root cause. Afternoon crashes often come from blood sugar dips, dehydration, or simply not moving enough. Sometimes a glass of water and a 10-minute walk does more than another cup of coffee. What This Means for Your Coffee Routine Look, we're not here to tell you that your morning ritual is wrong. If you love that first cup at 6 a.m. and it works for you, keep doing it. But if you've ever felt like coffee isn't giving you the energy it used to, or if you're struggling with afternoon crashes or sleep issues, timing might be the lever worth pulling. Here's a simple framework based on the research: Morning Protocol: Wait 90-120 minutes after waking for your first cup Optimal window: 9:30-11:00 a.m. for most schedules Pre-Workout Protocol: Drink 45-60 minutes before exercise Empty stomach for fastest effect Sleep Protection Protocol: Stop caffeine 6-8 hours before bed (minimum) 8-10 hours if you're sensitive For a 10 p.m. bedtime, aim for a noon-2 p.m. cutoff Frequently Asked Questions Does it matter what kind of coffee I drink? For timing purposes, what matters most is caffeine content. A typical 8 oz cup has about 95-100 mg. Espresso has more caffeine per ounce but less per serving (about 63 mg per shot). Cold brew tends to be higher in caffeine. The timing recommendations apply regardless of brewing method. Is it bad to drink coffee first thing in the morning? Not necessarily "bad," but potentially less effective. Your body is already producing cortisol to wake you up. Adding caffeine on top of that can lead to tolerance buildup and afternoon energy crashes. Research from Harvard shows coffee has health benefits regardless of timing, but strategic timing can improve how you feel throughout the day. How long does caffeine actually stay in your system? The half-life averages 5-6 hours, but ranges from 2-10 hours depending on genetics, age, medications, and other factors. That means if you drink 200 mg at noon, you could still have 100 mg in your system at 5-6 p.m. Should I drink coffee before or after breakfast? Both work. Before breakfast (empty stomach) means faster absorption and a quicker energy boost. After breakfast means slower, more sustained energy. If coffee bothers your stomach, eating first usually helps. Can I build tolerance to caffeine timing effects? Yes. Habitual coffee drinkers show reduced cortisol response to caffeine. But the sleep-disrupting effects don't diminish as much with tolerance, caffeine still blocks adenosine receptors even if you don't "feel" it as strongly. Finding Your Optimal Timing Everyone's body is different. The research gives us useful guidelines, but you're the best judge of how coffee affects you. Pay attention to your energy levels throughout the day. Notice how well you sleep. Experiment with timing and see what changes. At Ember, we think great coffee deserves to be enjoyed at its best, and that means getting the timing right for your body. Our small-batch, air-roasted beans are designed to taste clean and smooth whenever you drink them. But if you can optimize when you drink them too? Even better. Shop our air-roasted coffees →

Espresso is a concentrated coffee brewed by forcing hot water through finely ground coffee under high pressure (9 bars). Regular drip coffee uses coarser grounds and gravity-based brewing. This results in espresso being thicker, stronger-tasting, and more concentrated, but ounce-for-ounce, it actually has less caffeine than drip coffee. If you've wondered why a tiny shot of espresso tastes so different from a cup of regular coffee, here's the full breakdown. Brewing Method: Pressure vs Gravity Espresso Uses high pressure (9 bars, about 130 PSI) Finely ground coffee (almost powder-like) Water temperature: 190-205°F Brew time: 25-30 seconds Result: 1-2 oz concentrated shot Drip Coffee Uses gravity (water drips through grounds) Medium grind Water temperature: 195-205°F Brew time: 5-6 minutes Result: 8-12 oz cup The pressure in espresso brewing extracts coffee compounds much faster and more completely than gravity-based methods. Grind Size Matters Espresso requires a very fine grind, almost like powdered sugar, because water passes through quickly under pressure. If the grind is too coarse, water rushes through too fast and the espresso tastes sour and weak. Drip coffee uses a medium grind (like coarse sand) because water moves through more slowly. The right grind ensures proper extraction over the 5-6 minute brew time. Taste and Texture Espresso Intense, concentrated flavor Thick, syrupy body Crema (golden foam layer on top) Bold, sometimes bitter notes Smooth mouthfeel Drip Coffee Balanced, mellow flavor Lighter body No crema More subtle flavor notes Thinner texture Espresso's concentrated nature amplifies both the good and bad characteristics of beans. This is why quality beans matter even more for espresso. Caffeine Content: The Surprising Truth Here's where it gets interesting: espresso has LESS caffeine per ounce than drip coffee, but more caffeine per serving in some drinks. 1 oz espresso shot: 60-80mg caffeine 8 oz drip coffee: 80-100mg caffeine Double shot latte (2 oz espresso): 120-160mg caffeine 12 oz drip coffee: 120-150mg caffeine Per ounce, drip coffee wins. But espresso-based drinks often use multiple shots, so a latte might have as much caffeine as a cup of coffee. Equipment Differences Espresso Machines Require high pressure pump (9 bars) Expensive ($200-$3000+) More complex to operate Need a good grinder (burr grinder essential) Drip Coffee Makers Simple gravity-based brewing Affordable ($20-$300) Easy to use Basic grinder works fine You can make excellent drip coffee with minimal investment. Espresso requires more equipment and skill. Bean Selection Any coffee bean can technically be used for either method, but preferences differ: Espresso Often uses darker roasts (traditional Italian style) Medium roasts work great for modern specialty espresso Blends are common (for consistency) Drip Coffee Light to medium roasts showcase origin flavors Single-origin coffees shine Wider variety of flavor profiles At Ember, our air-roasted beans work beautifully for both espresso and drip coffee because they're roasted evenly inside and out. Common Espresso-Based Drinks Espresso: Straight shot, 1-2 oz Americano: Espresso + hot water (similar to drip coffee) Latte: Espresso + steamed milk Cappuccino: Espresso + steamed milk + foam Macchiato: Espresso + dollop of foam Cortado: Espresso + equal parts steamed milk All of these start with espresso as the base. Which Is Better? Neither is "better", they're different tools for different preferences: Choose espresso if you want: Intense, concentrated flavor Quick brewing (under 30 seconds) Base for milk drinks (lattes, cappuccinos) Thick, rich texture Choose drip coffee if you want: A full cup to sip Mellow, balanced flavor Simple brewing process More affordable equipment Frequently Asked Questions Is espresso just strong coffee? No. Espresso is a brewing method, not a strength level. It's concentrated, but that's different from "strong." You can make strong drip coffee by using more grounds. Can I use espresso beans for drip coffee? Yes. "Espresso beans" is a marketing term, they're just coffee beans, often darker roasted. They'll work in a drip machine, though they might taste more bitter than beans roasted for drip. Can I make espresso without a machine? Not true espresso (which requires 9 bars of pressure), but you can make concentrated coffee with a Moka pot or AeroPress that's similar in strength. Why is espresso more expensive? Equipment costs, skill required, and the amount of coffee used per serving. A double shot uses about the same coffee as a full cup of drip, but yields only 2 oz. Does espresso have more caffeine than coffee? Per ounce, no, drip coffee has more. Per serving, it depends on the drink. A double-shot latte has similar caffeine to a cup of drip coffee. Espresso and Coffee: Two Paths to Great Brew Espresso and drip coffee are distinct brewing methods that produce very different results. Espresso is concentrated, intense, and fast. Drip coffee is balanced, mellow, and forgiving. Whichever method you prefer, start with quality beans. Our air-roasted organic coffee works beautifully for both espresso and drip, clean flavor, consistent roasting, and freshness you can taste. Shop our air-roasted coffees →

Coffee stimulates bowel movements by increasing colon activity, triggering the release of gastrin (a hormone that speeds up gut motility), and stimulating the production of bile. For many people, this "gastrocolic reflex" kicks in within 4-20 minutes of drinking coffee, which explains why your morning cup doubles as a bathroom timer. But here's the interesting part: it's not just the caffeine. Decaf coffee has a similar effect, which means other compounds in coffee are at play. Let's break down the science. The Gastrocolic Reflex (Your Gut's Wake-Up Call) When you drink coffee, your stomach produces gastrin, a hormone that signals your colon to start contracting. This is called the gastrocolic reflex, and it's your digestive system's way of making room for incoming food. Coffee is particularly good at triggering this reflex. Research shows coffee increases colon activity by about 23% more than water and 60% more than decaf coffee (though decaf still has some effect). Why Does It Happen So Fast? Coffee hits your stomach, your stomach releases gastrin, and your colon gets the signal to contract, all within minutes. For some people, this happens so predictably they can set a clock by it. It's Not Just the Caffeine If you've assumed caffeine is the reason coffee sends you to the bathroom, you're only partly right. Caffeine does stimulate intestinal muscles, but decaf coffee triggers bowel movements in about 30% of people too. So what else is happening? Chlorogenic Acids These compounds in coffee increase stomach acid production, which speeds up digestion. More stomach acid means faster breakdown of food, which can lead to quicker bowel movements. Coffee Oils Coffee contains oils that can act as mild laxatives. These oils stimulate bile production, which helps your body digest fats, and that process can speed up the journey through your digestive system. Acidity Coffee is acidic (typically a pH of 4.5-5.5), which can irritate the stomach lining in some people. Your body's response? Speed things through the system to reduce irritation. Why Some People Are More Affected Than Others About 30-40% of people experience the coffee-poop connection strongly. If you're one of them, a few factors might explain why: You Drink Coffee in the Morning Your colon is naturally more active in the morning. Drinking coffee during this window supercharges the effect. Afternoon coffee might not have the same urgency. You Drink It on an Empty Stomach Without food to buffer it, coffee's acidity and gastrin-stimulating properties hit harder. This is why morning coffee (before breakfast) often triggers the strongest response. You're Sensitive to Acidity High-acid coffee can irritate your digestive tract. People with IBS, acid reflux, or sensitive stomachs often feel this more acutely. If you're one of these people, switching to a lower-acid coffee can make a real difference. Air-roasted coffee, like what we make at Ember, tends to be gentler on your stomach because the beans are roasted more evenly, without the burnt, bitter compounds that come from drum roasting. You Add Dairy or Sweeteners Lactose intolerance is more common than people realize. If you're adding milk or cream, that might be the real culprit behind your bathroom sprint. Same goes for sugar alcohols in flavored creamers. Is It Good or Bad That Coffee Makes You Poop? For most people, it's neither, it's just what coffee does. But context matters: It's Helpful If You're Constipated Coffee can be a gentle, natural way to stimulate bowel movements. Many people with sluggish digestion rely on their morning cup to keep things regular. It's Problematic If You Have IBS or Diarrhea If you already have loose stools or an irritable bowel, coffee can make it worse. The increased gut motility and acidity can trigger cramping, urgency, or diarrhea. It's Annoying If You're Always on the Go If coffee sends you to the bathroom right before you need to leave the house or during important meetings, timing becomes an issue. Drinking your coffee earlier or switching to decaf might help. Does Decaf Coffee Make You Poop? Yes, but less consistently than regular coffee. About 30% of people report a laxative effect from decaf, compared to 50-60% with regular coffee. Since decaf still contains chlorogenic acids, coffee oils, and some caffeine (2-5mg per cup), it can still stimulate your digestive system, just not as strongly. How to Reduce the Effect (If You Want To) If coffee's laxative effect is disruptive, here are strategies that might help: Drink Coffee After You Eat Food in your stomach buffers coffee's acidity and slows absorption. This can reduce the intensity of the gastrocolic reflex. Switch to Lower-Acid Coffee Dark roasts are slightly less acidic than light roasts, and air-roasted coffee is naturally gentler than drum-roasted coffee. Trying a different roast or roasting method might make your gut happier. Avoid Dairy If You're Lactose Intolerant Try black coffee, or switch to oat milk, almond milk, or another non-dairy alternative. If the problem goes away, dairy was the issue, not the coffee. Reduce Caffeine Gradually Try half-caf (half regular, half decaf) and see if the effect lessens. You might find a sweet spot where you still get the energy boost without the urgent bathroom trip. Time Your Coffee Strategically Drink it 30-45 minutes before you need to leave the house, giving your body time to do its thing. This turns the effect into a feature, not a bug. Frequently Asked Questions Is it normal for coffee to make me poop every single time? Yes, for about 30-50% of people. It's a predictable physiological response to coffee's effects on your digestive system. As long as you're not experiencing pain, diarrhea, or other concerning symptoms, it's normal. Why does coffee make me poop but tea doesn't? Coffee contains more chlorogenic acids, oils, and generally more caffeine than tea. These compounds trigger stronger gut motility. Tea has caffeine but lacks the same laxative cocktail. Can coffee cause diarrhea? In some people, yes, especially if you have IBS, drink coffee on an empty stomach, or consume large amounts. If you're experiencing frequent diarrhea after coffee, try reducing your intake or switching to a gentler, lower-acid option. Does cold brew make you poop less than hot coffee? Cold brew is less acidic (because it's never heated), which might make it gentler for some people. But it still contains caffeine and coffee oils, so it can still stimulate bowel movements, just potentially less aggressively. Will switching coffee brands help? Maybe. Different coffees have different acidity levels, roast profiles, and compound compositions. If one coffee bothers your stomach, another might not. Air-roasted, organic coffee tends to be cleaner and less irritating. Your Morning Coffee, Your Morning Routine Coffee's laxative effect is a natural response to a complex mix of caffeine, acids, oils, and hormones. For many people, it's a helpful part of their morning routine. For others, it's an inconvenience that can be managed by adjusting timing, roast type, or brewing method. If coffee is harsh on your stomach, it's worth exploring lower-acid options. Our air-roasted organic coffee is naturally gentler, cleaner flavor, less acidity, and easier on your digestive system without sacrificing that morning ritual. Shop our air-roasted coffees →
