lemonade - countable or uncountable

Question

Is "lemonade" countable or uncountable? Could I say the following sentence?

Could you please bring me a lemonade?

Or must I say "a glass of lemonade" ?

Answer 1

"Lemonade" is usually uncountable, but it can be used as a countable noun to mean "a glass of lemonade". It is uncommon, but possible, to treat "lemonade" as a countable noun.

This applies not only to lemonade but to most beverages.

Answer 2

Or must I say "a glass of lemonade" ?

You don't need to.

From Collins

A glass of lemonade can be referred to as a lemonade. Example: I'm going to get you a lemonade.

Take a look at the following Q and A.

What can I get you?

• A diet coke, please!
• A can of diet coke, please!

They are both idiomatic. The "a can" or "a glass" is implied.
