My assessment process for a espresso machine at home is similar to how I try the standard drip coffee maker. First, I washed the hand and dried all the removal parts and accessories. For most espresso makers, that includes filter basket, metal portafilter inserts, water tanks and so on. Next, I ran a brew cycle with hot water to wash any remaining material from making.

Most automated espresso machines, apart from super-automatic models, lacking an integrated coffee And I’d rather try the espresso machines with a new grind coffee, no preground coffee, so I supply my own grinder: the Breville Smart Grinder Pro. I choose this conical burr grinder for two reasons. First, it is more calibrated for espresso than drip or other brewing styles. That means it produces a grind coffee seeds so good. Second, the size of this recovery is always equal. The two reasons are important for a proper process of making espresso.

To get the shots, I will start the proposed method set out in the machine product manual. Usually occupied the number of coffee grounds expected per shot, along with any instructions about the level of stiffness. Also, I follow the tamping instructions (light, medium or hard tamp) if it is given to the manual.

If possible, I will mix double shots in espresso for all my test run. I assure record the weight of the grounds I use, plus the weight of espresso in every shot I pulled. This data, with readings from a portable refractometer, allowing me to calculate two important percentages: total dissolved solids and extraction percentage.

Like any brew of coffee, the best percentage of extraction of espresso than between 18% and 22%. It provides a balanced cup, if you make the same and efficient taking coffee compounds from your yard (both taste and caffeine).

If you over-extract, you are at risk of losing bad tastes (bitterness) after good. At the opposite end of the standard, the unclaimed brews are likely to have undeveloped tastes. Lack of sugar and other caramelized organic chemicals, these shots taste aslom, weak and watery.

Unlike a cup of coffee drip, the quality of the espresso’s barista should concentrate. Good drop usually has a percentage TDS of 1.3% or 1.4%, good espresso has a higher percentage. Breville Barista Express, for example, makes shots with percentages of TDs as high as 12.4%.

The seeds I pulled balance, with the acquisition of 18.6%. Test coffee seeds I use is the same kind I use for regular coffee makers – Costco Kirkland Colombian. This is a medium-dark stew that is also suitable for making espresso.

Finally, I tried my hand to the Milk Frothing on every coffee machine furnished with steam wand. I recorded the total steam wand experience, if the process is a sudden, a tough task or anywhere in between.
