Using a coffee scale for double shots is one of the best ways to ensure consistency and quality in your espresso
The standard double shot uses between 18 and 20 grams of coffee to produce roughly 60ml of liquid espresso
Instead of guessing based on timer readings or cup fill lines, a scale lets you track exact input and output, ensuring consistency and قهوه پارتاک superior taste
Start by placing your portafilter on the scale and taring it to zero
By taring, you isolate the exact amount of ground coffee being dosed
Grind your coffee straight from the grinder into the portafilter basket
Adjust your dose within the 18–20g range based on your equipment and desired strength
Beginners often succeed with 18g, but feel free to experiment with 17.5g or 19.5g to fine-tune flavor
After dosing, gently redistribute the grounds using a tool like a WDT or your fingertip
Tamping ensures a level, dense puck—use consistent downward pressure to avoid channeling
A level tamp promotes uniform extraction and prevents water from tunneling through weak spots
Reset the scale to zero after tamping to measure only the extracted espresso
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
Many professionals consider the 1:2 ratio the gold standard for balanced double shots
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
Keep a record of your doses and yields
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
While measuring adds a few seconds to your routine, the improvement in consistency is undeniable
You’ll stop guessing and start knowing exactly what your espresso is doing
Consistent results come from measurement, not luck—scale-based brewing is the ultimate path to espresso excellence
