Thank you for your reply.
Based on those, I investigated again.
Screw top aluminum bottles were about twice as expensive as aluminum cans.
It's just the range I investigated.
High priced bottle.
It costs a lot to introduce new equipment.
I think the reason why screw tops are not popular is...
I heard that aluminum cans have excellent characteristics, but they have a large diameter and are easily oxidized during filling.
Therefore, I think that a screw-top aluminum bottle has a small diameter and is hard to oxidize, but I have never seen such a craft beer.
I've seen Budweiser.
Why...
