Short glass with dosing lines

A practical and convenient short glass for measuring the extraction of our espresso coffee at the correct times

22-28 seconds is the time it should take our espresso machine to deliver 30 ml of espresso, including crema. Because an excellent espresso coffee is a serious matter, and a slower extraction (which will give more bitterness and caffeine) or shorter (to have acidity and little body) would bring unwanted substances and sensations into the cup.

This graduated glass marks the doses for the single espresso 30ml and for the double 60ml. This glass is made of Pyrex which is the same material that baking trays are made of: therefore no risk of burning yourself!
It should be noted that measuring the quantity of espresso should be accompanied by weighing it in order to find an optimal espresso of 30 grams per cup. The measurement can be distorted if only the quantity is evaluated, especially in very creamy coffees.
