If a barista makes 200 double shots a day, how much coffee waste occurs in a single week?

To determine the coffee waste that occurs in a single week from making 200 double shots a day, we first need to establish how much coffee is typically wasted for each double shot.

In standard practice, a double shot of espresso typically requires about 18 to 20 grams of coffee per shot. For the sake of calculation, if we assume an average of 18 grams per double shot, this leads us to about 36 grams of coffee per day for 200 double shots.

Calculating the daily waste:

• 200 double shots x 18 grams = 3,600 grams of coffee used in a day.

However, some of that coffee will be wasted due to grounds left in the portafilter, spillage, and other factors. In professional settings, it's common to estimate that a barista might waste about 10% of their coffee grounds.

Thus, the waste from the coffee grounds would be approximately:

• 10% of 3,600 grams = 360 grams of waste daily.

Over the course of a week (7 days), this waste would accumulate as follows:

• 360 grams x 7 days = 2,520 grams of coffee waste in a week.

However, if we
