The Importance of Timing and Weighing Your Shots

Pulling the perfect shot of espresso is a learning experience. It's not easy to go from beginner to proficient at such a delicate process. We've talked in the past more generally about ways to improve your espresso game. Today we wanted to take a look at timing and weighing shots, two key components of brewing great espresso!

Shot Weight

Shot weight is important because, as with drip coffee, ratio is key. You need the right amount of water to pass through just the right amount of ground coffee. This ensures that the chemical process of coffee and water molecules bonding takes place. For drip coffee, using a 1:16 ratio of coffee to water is pretty standard. Due to espresso's more concentrated, syrupy nature and the pressure from brewing, 1:2 coffee to water is a good starting point. Using a scale to weigh your shot as it pulls is key here! While you can also use a shot pitcher that measures volume, a scale gives you more freedom. With it, you can brew to exact ratios and try different amounts of coffee and water.

The important thing here is making sure your scale can accommodate you portafilter for weighing grounds AND be small enough to fit under the brewhead. Examples like the Acaia Lunar are small enough to fit under brew spouts and can be combined with plates to fit portafilters.

Shot Timing

In order to manage the perfect extraction, the amount of time a shot takes to pull is very important. Most of the time you'll be aiming for your shot to pull in 20-30 seconds. For more adventurous recipes you might use different timings. If your shot pulls very fast it could mean that you need a finer grind or a tighter tamp. Too long and you may need the opposite. In either case, without timing your shots you'll never know for sure.

Poorly extracted shots can taste sour or bitter, just generally bad. If the timing is good and you use the right volume of coffee and water, you know that it's a problem with the bean! Many scales offer shot timers, but to truly measure down to the millisecond, try to find a brewer with one built in. Timers on machines will usually start automatically when the shot begins to pull. This ensures everything is synced up exactly. Check out this year's the Rocket Giotto for a great machine with built in timer.

We hope this article drives home the important of adding a timer and scale to your espresso setup!
