I think they’re called growlers.
So these are for wine bottles, it is retrofit with the collar, it isn’t just the flip cap.
IKEA sells bottles like this
The Ikea bottles warn against using their bottles for pressurized uses. Iir the glass isn’t rated for that.
Also, nothing I’ve used flip caps for has kept carbonation well after priming.
In the post it is explained that it is meant for reusing wine bottles not buying new ones. And it mostly doesn’t matter that it can’t be used under pressure because it is for syrups and other non pressure stuff.
Ah, that’ll work then. Missed that part.
Thrift stores, virgil’s root beer sells some of their drinks in swing tops, trader joe’s ginger beer is in a swing top. Or you can just buy them online.
Do they need to be wine bottle shaped?
If swingtops that are shaped for beer work for you, find a local independent bar or pub. Stop by before opening and ask if they’d mind saving their swingtops for you.
When I did this, the answer “Sure, just bring one back for me with your first brew.” More, they already had a box of them set aside.
Grolsch bottles are by far the most common and will be 450ml, green, and with a raised glass patterning. Those are the most common. 9 ounce bottles from small commercial breweries will be smooth clear or brown with paper labels you’ll want to soak off, and they’ll have significantly fewer of these.
The OP on mastodon is looking only for retrofit non returnable wine bottles.
Grolsch comes in them, but many brewshops sell swingtops
My local homebrew shop used to sell these. I think they stopped selling it since people used bottles which couldn’t take the pressure.
What were you planning on using them for?
