A new study found that the most common way to cool a machine is by placing it in the freezer.

The study found this method worked best for the most expensive machines, such as espresso machines, and cost about $20 per unit.

The research also found that when the machine was frozen, the heat from the machine’s exhaust was absorbed by the coffee and coffee grounds and not dissipated by the machine.

So if you’re looking to reduce the cost of your espresso machine, this study is definitely worth a shot.
