Keep tabs on your high-test java when using espresso machines by following these tips, too. First, remember that espresso should only take 15 to 20 seconds to brew in machines that have good pumps. You should see a darkish-brown foam, called crema, on top while the espresso is dripping into the cup. Then, when all of the tasty essence of the espresso is extracted, the liquid dripping out of the filter will be a whitish-brown. That s when you need to put a stop to your brewing process, or else you risk a funky tasting espresso.
You can tell you followed these steps correctly by measuring your finished product. A properly created espresso will be one to one and a half fluid ounces: approximately the size of a liquor shot glass, or for you kitchen experts, about a half of a small demitasse cup. Any more, and you might have forced more water through the grounds than appropriate. In this case, espresso machines will impart a bitter taste. Hopefully, however, this advice has helped you create the perfect pour of espresso.
