The serving suggestions dilution ratio depends on how strong you like your coffee.
If you love a really strong coffee, you could drink it straight as is.
You can dilute this cold brew with either water or milk or both.
Start with a ratio of 2:1 (2 parts cold brew and 1 part water or milk) and work your way up from there.
You can prepare a cold brew either in a French Press (the french press cold brew ratio will be the same) or in a mason jar.
You can also make a decaf version!
