I have a porter in the keg now and would like to give it a little sourness. Is it possible?
Latic acid
How much?
Not sure, I would grab a pint and add it drop by drop, taste in between. Then just scale up from there. This way if you don’t like the effect you only waste a pint. I don’t think it will take much but it depends on how sour or tart you want and what percent latic acid you get. are you just trying make it a little tart?
Yea. I made a porter and I think just a little tartness might be appropriate
Just a heads up I have never done this before but have heard of people doing this to stouts. Either way your only risking a glass of beer. Let us know how it works out if you try it.
