A correct grinding is fundamental to make the authentic Italian espresso: not too coarse or you’ll get a watery coffee and not too fine or coffee won’t come out. Moreover, different beans react best with different grind sizes. Optiaroma allows to regulate the amount of ground coffee used per cup, for a light or strong taste according to one’s preferences. Adding more coffee makes it harder for the water to go through, slowing down the extraction time and resulting in a stronger coffee. Pre-brewing affects the intensity, and could be set to have a stronger coffee. With this process, ground coffee are moistened with hot water for some seconds before the actual brewing, releasing a wider range of aromas.
We suggest to use whole cold milk (at circa 5° C / 41° F), with a protein content of at least 3% and a fat content of at least 3.5%. Proteins will incorporate air in the cream, while fats will make it dense and steady. Also semi-skimmed cow milk, some lactose-free milk and soy drink are proven to deliver a good result.
Scale is a normal consequence of using the machine, and it depends also on the quality of the water you use. It is necessary to descale the machine when the display alerts you to proceed. We suggest to follow the step-by-step procedure illustrated in the instruction booklet and to use only the GAGGIA descaler that is especially thought especially for our espresso machines.
Drip tray, drip tray plate, coffee pucks container, water tank, pannarello, cappuccinatore, CappinCup and milk carafe are removable and should be washed under tap water, with a bit of dish soap, but no abrasive substances nor solvents. The removable brew group must be washed with no soaps. The drip tray plate can be washed also in the dishwasher.
To descale your Gaggia coffee machine use only the Gaggia decalcifier, a unique solution made to ensure excellent performances of the machine throughout time. Vinegar and any other descaling agents must be avoided. Never use descaling agents based on mineral acids such as sulfuric acid, hydrochloric acid and sulfamic acid. These descaling agents may damage your coffee machine’s pipe and tube system.
