Measuring Espresso Volume

#1: Post by **David6FL** » November 19th, 2022, 1:59 pm

Just have a quick question. I decided to measure my extraction ratio. I am using 18 grams of coffee and weigh 1.5 ounces of espresso. My question is do I call the measurement 1.5 ounces when the crema reaches the 1.5 mark or when the dark espresso under the crema reaches the 1.5 mark? I have been using the espresso reaching the 1.5, not the crema, and getting 39 grams of espresso.

For measuring the brew ratio, use weight, not volume. From Brewing ratios for espresso beverages:

You can measure volume if you like, but since crema volume varies widely, it's not really that informative.

As Dan notes, use weight (not volume). Your brew ratio is 18/39 = 46%, well within the normale range.
