>>3556297>>3556298I'm using Martens beer 1 liter bottles I randomly found at the local supermarket. pic related, stolen from google.
they were like $2 a piece. I just bought them for the bottles lol, didn't got to actually taste the beer.
they're made of plastic and have an hermetic screw cap so you can squeeze all the air out. fill with glass marbles when liquid is running low to displace air.
