People spray espresso beans with a tiny mist of water before grinding (Ross Droplet Technique or RDT) primarily to reduce static electricity, which prevents messy grounds from flying around and sticking in the grinder, leading to cleaner workflow, less waste, and more consistent dosing for better-tasting espresso. This technique combats the static generated during grinding, which causes grounds to cling to surfaces, and it helps reduce clumps and retention in the grinder.
The purpose of water spraying is to help the physical grinding process rather than to directly affect the final cup of coffee. The hypothesis is that a light spritz of water helps combat the static created during grinding, ultimately reducing the mess produced by the grinder.
Espresso is served with a small glass or sip of water for three practical reasons: palate preparation, palate cleansing, and sensory calibration. Palate preparation: drinking a sip of water before the espresso neutralizes lingering tastes (from food, gum, tobacco, strong spices, or toothpaste).
The "espresso 30-second rule" is a widely used guideline suggesting an ideal espresso shot should extract in 25-30 seconds for a balanced flavor, acting as a starting point for dialing in your grind size and brew ratio, though taste remains the ultimate judge, as factors like roast level and machine type can alter this. Timing usually starts when the pump activates, but some prefer from the first drip; shots under 20 seconds are often sour (under-extracted), while over 35 seconds can be bitter (over-extracted).
The Golden Rule
A reliable method for judging your extraction times is by following the “Golden Rule” which states that a double shot of espresso should result in about 2-2.5 fluid oz and take about 20-25 seconds to extract.
Mistake #1: Using Old Coffee Beans. Mistake #2: Using the Wrong Coffee Grind. Mistake #3: Forgetting to Clean Your Espresso Machine. Mistake #4: Tamping Your Coffee Incorrectly. Mistake #5: Not Preheating Your Machine and Cups.
In Italy it's now a classic: you go into a bar, order an espresso and the bartender next to the cup also serves you a glass of water. This gesture has become almost natural and, in many places, it is automatic for the barista to accompany the coffee with water, without even being asked.
According to emerging research in circadian biology and neuroscience, waiting about 90 minutes before having caffeine can improve focus, mood, and nighttime sleep quality. It's not about giving up your morning brew — just about timing it to align with your body's natural cortisol rhythm.
Medical experts advise using unsweetened cocoa powder to boost heart health via powerful flavour flavanols. This addition increases nitric oxide production, which relaxes blood vessels and improves overall blood circulation.
Yes, espresso requires a fine grind to ensure proper extraction and the characteristic strong flavor and crema.
Cowboy coffee generally refers to coffee boiled in a vessel (such as an enamel pot) directly over an open fire, poured straight from that pot into cups and consumed. I'm generally of the opinion that the simpler the brew method the better, so this appeals to me greatly.
Coffee beans contain large concentrations of these acids, which belong to the aromatic phenolic acid group. These contribute heavily to coffee flavour and aroma. “Reheating coffee will break down chlorogenic acids, which releases caffeic and quinic acids,” Verônica explains.
The 80/20 rule for coffee (Pareto Principle) means 80% of your flavor comes from 20% of the effort, focusing your energy on key variables like fresh, quality beans, proper grind size, good water, and correct ratio, rather than obsessing over every minor detail. It suggests prioritizing high-quality beans and core techniques to get the best flavor, recognizing that superior beans in a decent brew beat average beans in a perfect brew, with the remaining 20% of effort refining the process for a great cup.
Gen Z tends to be more health-conscious and aware of what they're putting into their bodies. Iced coffee allows for healthier modifications that might be less appealing in a hot beverage. For instance, opting for less sugar, choosing plant-based milk, or adding cocoa or protein powder is easier with iced coffee.
The 1-week coffee rule refers to a recommended approach to cutting out coffee, where you gradually reduce your coffee intake over a week.
Late afternoon or evening: Because caffeine stays in your system for 6–8 hours, drinking coffee after 3pm can interfere with your ability to fall asleep or stay asleep. Poor sleep can snowball into relying on even more caffeine the next day, creating a cycle of fatigue.
Coffee in the morning can have some potentially adverse effects on the body—dehydration, upset stomach, and cortisol level increases, to name a few.
When you measure total coffee consumption per capita (per person per year), the leader is crystal clear - and it's Finland. YES, Finland drink more coffee per person than anywhere else in the world.
The "2-hour coffee rule" suggests waiting 90 minutes to 2 hours after waking up to drink your first cup of coffee to optimize caffeine's effects, avoid interfering with your natural cortisol spike (which peaks shortly after waking), and potentially prevent afternoon energy crashes. This timing allows caffeine to work better when cortisol levels naturally drop and adenosine (the chemical that makes you sleepy) builds up, leading to better focus and alertness later in the day, though individual experiences vary.
The Italian version of “cheers,” salute derived from the Latin language, and was a word Roman soldiers used as a greeting. Italians use the same word to wish others good health, especially when sharing a drink together!
There is also some evidence that drinking coffee can reduce your risk of liver damage like scarring and cirrhosis. Beneficial effects have been found for filter, espresso, and instant coffee. But drinking coffee cannot always prevent liver disease.
A reminder - fresh roasted coffee's rule of 3's. Ground coffee - 3 minutes, roasted coffee - 3 weeks, raw coffee - 3 years. Now, let's take a more precise look at those rules of 3. Raw coffees may last forever, but in Australia's harsh climate, 12 months can strip 25-50% of the quality of a high-grade green coffee.
The 4 M's of Espresso — Miscela, Macinatura, Macchina, Mano. (That's blend, grind, machine, and hand — for the non-Italian speakers.) Let's break it down the 787 Coffee way, so you can make better coffee at home, learn more about the process, and fall even deeper in love with what's in your cup.
