My father-in-law brought me some caps he had in the basement since he knows I’m into brewing beer. They are crown caps with cork liners. Not rubber/plastic ones.
I’m not gonna use them (I didn’t tell him that) but I was wondering if anyone knew when they stopped making these? There’s a good chance they’ve been in his basement for a long, long time.
My mother-in-law offered me a bag of those a couple years back. The ones she had were from the mid-70’s. The ones you have could be quite old.

Use a couple of them for fun, and give those bottles to your FIL
