Using a coffee scale for double shots is one of the best ways to ensure consistency and quality in your espresso

A double shot typically refers to about 60 milliliters of espresso extracted from 18 to 20 grams of ground coffee

Time-based extraction is unreliable—using a scale removes the guesswork and lets you dial in your perfect shot every time

Before adding coffee, zero out the scale with the portafilter resting on it

Taring eliminates the basket’s mass, letting you measure pure coffee weight

Next, grind your beans directly into the portafilter

Adjust your dose within the 18–20g range based on your equipment and desired strength

Begin with 18g if you're new—many find it balanced, but tweak to 17g or پارتاک کافی 19g depending on extraction

Once you’ve added the coffee, use a distribution tool or your fingers to level the grounds evenly

Apply steady, vertical pressure to form a smooth, compact coffee bed

This helps water flow evenly through the coffee bed

Tare the scale once more after tamping to isolate the yield weight

Your setup is now precise—initiate the shot with full control

Monitor the scale in real time as the espresso flows

The ideal double shot yield falls within the 36–40g range

A 1:2 yield ratio ensures rich extraction without over- or under-extracting

This ratio often produces a balanced shot with good body and flavor

If your shot runs too fast and you get less than 36 grams, your grind is probably too coarse

If it runs too slow and you get more than 40 grams, your grind is likely too fine

Log every shot’s dose, yield, time, and grind setting

Track extraction duration, burr setting, and flavor notes like sweetness, acidity, or bitterness

Over time, you’ll learn what works best for your beans and equipment

Tweak your dose by 0.5g or adjust yield by 2g—tiny shifts yield dramatic flavor results

The extra minute spent weighing pays off in flawless, repeatable espresso

You’ll transition from guessing to data-driven brewing with complete confidence

That’s the key to brewing great double shots every time
