re: Espresso machine

I use Third Wave minerals in distilled water that I get by the gallon from Target.

My coffee roaster distills his own water and adds 1/2 teaspoon Himalayan pink salt and 1/4 teaspoon baking soda to remineralize.

There’s a million recipes, like Barista Hustle, and R Pavlis water.

Baton Rouge tap water would run a high risk of dropping scale, messing up your system.
