"Dialing in" sounds like jargon, but it just means adjusting your grinder and recipe until a specific coffee tastes its best. Every coffee is a little different, and even the same coffee changes as it ages. Dialing in is how baristas keep shots tasting sweet anyway. Here's the calm, repeatable version for home.
The Three Numbers
Espresso has exactly three variables that matter at the start:
- Dose: grams of dry coffee in the basket (pick 18g and never change it during dial-in)
- Yield: grams of liquid espresso in the cup (target 36g, a 1:2 ratio)
- Time: seconds from pump on to shot done (25 to 30 is the healthy window)
Dose and yield are decisions you lock in. Time is the readout that tells you whether your grind is right.
The Process
1. Pull a baseline shot
18g in, stop at 36g out, note the time. Don't judge the first one. Just record it.
2. Read the time
Under 20 seconds: water raced through, the shot is likely sour and thin. Grind finer. Over 35 seconds: water crawled, the shot is likely harsh and bitter. Grind coarser.
3. Change only the grind
One notch at a time, one shot per change. Touch nothing else. This is the discipline that makes dialing in fast instead of endless.
4. Taste, then trust your tongue
When the time lands in the window, taste. Sour means go slightly finer. Bitter means slightly coarser. Sweet, rich, and balanced means you're done. Write the settings down.
When to Re-Dial
Expect small adjustments when you open a new bag, when the beans are a few weeks older, and when the seasons change humidity. It's usually one notch, not a fresh start.
A Note on Patience
Dialing in takes three to six shots. That's not failure, that's the craft. There's something almost devotional about it: small adjustments, honest attention, and the reward of getting something exactly right. Our Resurrection Espresso is a forgiving partner for the process, with a wide sweet spot and milk chocolate notes that tell you clearly when you've found it. New to espresso entirely?
