I think you're confusing Molson dry with Labatt 50.
Old people don't want higher alcohol percentage..they want a harsh beer, without the high alcohol...so they go with Labatt 50.
Molson dry is a minimal aftertaste higher percentage alcohol beer.
It was a go-to among high school/college/university students a decade ago before the rise of craft beers/IPA etc.
Before it was, do you want 4% Coors light, Bud light, or corona...do you want 5% Budweiser, blue, or Canadian, and then do you want 5.5-6% dry beers like Molson dry.
I've seen a lot of teenagers and young adults drink Molson dry, but almost never a 50+ year old drink Molson dry.
But take Labatt 50...I've never seen a young person drink it....only old people.
I think the beer you're thinking of is Labatt 50.
