Can be used with any beer. Although the instructions state 1 drop per 375ml, we have found that for 500ml bottles use 1 drop, for 1 litre bottles use 2 drops. This provides sufficient carbonation for virtually all beers. If you want more fizz, add an extra drop to each bottle.
Carbonation Drops are a convenient, no mess, no fuss alternative to priming sugar. Many brewers find the bottling process to be mundane and tedious. With this in mind we have produced Carbonation Drops, which are designed to replace priming sugar. Carbonation Drops dissolve quickly without the need for inverting or shaking the bottle.
