I'm a barista, coffee houses were a relatively new thing in 1700. People from the Middle East and East Africa would probably understand "I make coffee", and maybe some very trendy Europeans as well (Wikipedia says the first coffee house in Europe opened in 1645 in Austria.)
If they weren't familiar with coffee, I'd say I make a beverage with the opposite properties of beer. It's hot and perks you up where beer is cold and dulls your senses.
(Random thought: how did beer refrigeration work pre-industrial revolution? Were our ancestors chugging lukewarm beer?)
