my wife got me abeer making kit for xmas and it says that i need 40 one leater bottles with lids and i thort that maybe just a couple of empty bottles of coke would do the job is this true or not will the beer go flat ???
When you get to the bottling stage, you will need to double up on the sugar ie. if the instructions say add one teaspoon per 1 litre bottle, add two teaspoons per (coke size) bottle - then it will be just as fizzy when ready.
Good luck and keep everything well sterilized.
