I bought this kit and this is my first brew. Could you please explain what are differences between 12L and 20L recipes? Will 12L be stronger or not? And will 12L variation be carbonized enough, if it says not to add priming sugar? Thanks!
Hi Jabberwok, unfortunately i am not so experienced in homebrew. But from my point of view having 12L instead of 20L may result in more quality beer.
As far as I understand all this process: Beer kit is just a can of hopped malt extract, which contains basic sugars and "other stuff". Sugars will be processed by yeasts into alcohol, "other stuff" will not be processed by yeasts and will give your beer taste, body, flavour and so on.
When you make 20L batch you have to use additional sugar to have your beer of necessary gravity (however it is recommended not to use table sugar).
After fermentation you will get beer with certain value of alcohol, but without full body.
In case of 12L batch you need to add nothing. This will result probably in the same gravity beer. But after fermentation you will get less alcohol but more body.
That is how do I understand this process. And you need to decide what do you expect from your beer.
But I have one concern regarding 12L batches - hops. I personally do not like strongly hopped beer. And level of hops in 12L batch will be significantly bigger that in 20L batch (just a guess).
But from the other side I can't predict how hopped will be your 12L batch. It may be fine for you.
I hope you will find this info useful.
