Beers sounds wrong, when people refer to a few beer"s" they say "beer", for example we'd say "Get the beer" not "Get the beers"..
It sounds rather strange to me in Hebrew as well, but I would understand it to mean multiple types, or brands, of beer. It could also be multiple bottles of beer, as yonatan1301 wrote.
“What's in those glasses? Ciders or beers?”
“I'm drinking beers. I have here a Pilsener, an IPA, and a stout.”
Why do I get a correction if I right the same letters. I right שותה and I get a correction written שותה
Yes, I feel this is confusing as well. "Beer" can be both a count noun and a non-count noun.
If I'm drinking multiple cans of a single type of beer, the plural is "beer" (non-count noun). If I'm drinking cans of multiple types of beer, the plural "beers" (count noun) would be idiomatic.
I think this sentence is ambiguous, and should allow both "beer" and "beers" to be correct translations of בירות.
This course has excessive references to alcoholic beverages rendering it inappropriate for kids.
