Is coffee a countable or uncountable?

Answer 1

The noun coffee is an uncountable noun as a word for a substance; units of coffee are expressed as a pot of coffee, a cup of coffee, a sack of coffee, a ton of coffee, etc. But like many nouns for substances, the plural form is used for 'types of' or 'kinds of'; for example:

This cafe has an interesting selection of coffees.

The plural form for substance nouns is reserved for 'types of' or 'kinds of'; for example:
