November 23 is National Espresso Day, a nod to Italy’s small but mighty gift to the coffee world. Espresso is not a bean or a roast but a method, hot water forced through finely ground coffee under pressure, and getting it right at home is a rewarding rabbit hole to fall into.
The grind is everything
More than any other variable, the grind decides your shot. Too coarse and the water rushes through, leaving a thin, sour espresso; too fine and it crawls out bitter and over-extracted. The target is a shot that flows in roughly twenty-five to thirty seconds. You adjust by grinding finer to slow the flow or coarser to speed it up, which is why a quality burr grinder is the best money you can spend on coffee at home.
Start with fresh beans
Espresso is unforgiving of stale coffee. Buy whole beans roasted within the last few weeks, keep them sealed away from light and heat, and grind them right before you pull the shot. Ground coffee sheds its aromatics within minutes, so the vivid, sweet complexity you want in an espresso simply is not there in a pre-ground bag. Fresh beans also give you that telltale layer of crema on top.
Speak a little Italian
Part of the fun is the vocabulary. In Italy, a caffe is simply an espresso, usually knocked back standing at the bar. A macchiato is an espresso marked with a small dab of milk foam. A cappuccino adds steamed and foamed milk and is traditionally a morning drink, rarely ordered after lunch. Knowing these makes ordering, whether at your counter or a bar in Rome, far more enjoyable.
A great shot starts with a good grinder and fresh beans; everything else is refinement.
Look after the details
Small things add up. Use filtered water, since espresso is almost entirely water and any off-flavors in your tap will land squarely in the cup. Warm your cup before pulling the shot so it does not go lukewarm on contact. And watch for that reddish-brown crema, a good sign your beans are fresh and your extraction is on track.
Go beyond the straight shot
Espresso is a building block as much as a drink. Pour a hot shot over a scoop of vanilla gelato for an affogato, shake it into an espresso martini, or stir it into warm milk for a homemade latte. If you are not ready for a machine, a stovetop moka pot brews a strong, espresso-style coffee that has fueled Italian kitchens for generations and costs very little.
How to celebrate
- 1Dial in the grind
Espresso lives and dies by the grind. Too coarse and the shot gushes out thin and sour; too fine and it drips slow and bitter. Aim for a shot that pulls in roughly twenty-five to thirty seconds, and adjust finer to slow it or coarser to speed it up. A good burr grinder is the single biggest upgrade you can make.
- 2Use fresh beans
Espresso punishes stale coffee. Buy whole beans roasted within the last few weeks, store them airtight and away from light, and grind them right before you brew. Beans start losing their aromatics within minutes of grinding, so pre-ground coffee never tastes as vivid in a shot.
- 3Learn the Italian ordering
In Italy, a caffe is just an espresso, ordered and downed standing at the bar. A macchiato is espresso marked with a dab of foam; a cappuccino is espresso with steamed and foamed milk, traditionally a morning-only drink. Knowing the terms makes ordering, at home or in Italy, far more fun.
- 4Make an affogato or a martini
Espresso is not only for drinking straight. Pour a hot shot over a scoop of vanilla gelato for an affogato, or shake it into an espresso martini for something stronger. Both turn a simple shot into dessert. The hot-cold contrast of an affogato is especially hard to beat.
- 5Mind the crema and the water
A well-pulled shot wears a layer of reddish-brown crema on top, a sign of fresh beans and a good extraction. Use filtered water, since espresso is mostly water and off-tasting tap water shows up in the cup. Warm your cup first so the shot does not cool the moment it lands.
