Best Shot Timers & Brew Timers

Extraction time is a primary espresso variable — integrated scale-timers that measure both weight and time simultaneously, compared at every price.

Why Timing Espresso Shots Matters

Extraction time is one of the three primary espresso variables (with dose weight and output weight). A 1:2 ratio (18g in, 36g out) extracted in 22 seconds produces a very different cup than the same ratio in 35 seconds — the faster shot is likely under-extracted (sour, thin), the slower shot over-extracted (bitter, harsh). Target extraction time is typically 25–35 seconds for most espresso ratios, with the specific target depending on grind fineness, bean characteristics, and intended ratio.

A shot timer removes the "I think it was about 28 seconds" variable from dialing-in. Combined with a scale (measuring output weight) and a grind size adjustment, precise timing gives you three data points per shot — enough to make targeted adjustments rather than random ones.

Top Picks

Acaia Lunar Scale with Timer

$$$

The reference combination for espresso — weight and time simultaneously on the same device. Bluetooth connectivity for the Acaia app. The most used precision tool in specialty espresso.

Check Amazon Check eBay

Felicita Arc Scale

$$

Acaia Lunar alternative at lower price — weight + time, Bluetooth, app connectivity. Thinner profile fits under most portafilters with less clearance reduction. Strong value vs the Lunar.

Timemore Black Mirror Basic+

$$

The accessible espresso scale — 0.1g accuracy, built-in timer, no Bluetooth (which most home baristas don't use). Simple, reliable, accurate. Best value espresso scale with integrated timer.

Basic Digital Kitchen Timer

$

Any timer accurate to 0.1 seconds — a $10 kitchen timer or even the built-in timer on most smartphones. Functional if you already have a separate scale. Inconvenient compared to integrated scale-timer units but completely accurate.

Shot Timer vs Scale Timer: The Practical Difference

A dedicated shot timer (separate from a scale) gives you one number. A scale with integrated timer gives you two — weight and time simultaneously without manual stopwatch involvement. The integrated approach is clearly superior for dialing in: you see dose weight before pulling, output weight and extraction time during and after. The Timemore Basic+ at its price point makes the choice straightforward.

☕ Recommendation

Timemore Black Mirror Basic+ for the best value integrated scale+timer. Felicita Arc if you want Bluetooth connectivity without the Acaia price. Acaia Lunar if you want the industry reference and use the Acaia app actively.

Frequently Asked Questions

What's the ideal espresso shot time?

25–35 seconds for a standard 1:2 ratio (18g in, 36g out) is the typical target range. Faster than 25 seconds usually means under-extraction (too coarse, too little dose, too high flow). Slower than 35 seconds usually means over-extraction or channeling. These are starting points — the target shifts based on bean, ratio, and taste preference.

Do I need Bluetooth on my espresso scale?

Only if you plan to use the app to log and review shot data — useful for systematic dialing-in across multiple sessions. For most home baristas, Bluetooth adds cost without changing daily workflow. The Timemore Basic+ without Bluetooth is functionally equivalent for in-session use.

Should I start the timer when I press the button or when espresso first drips?

Both conventions exist. Most home baristas and the specialty coffee community time from first drop — this measures actual extraction time rather than including pump preheating. Machines with pre-infusion make the 'first drop' moment distinct; mark it consistently across your shots for comparable data.
