Beginner and pro baristas share tips and tricks for making espresso.
← Back to Tips • 3 posts
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.

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