I was planning on making a stout pretty soon and I saw that one way to sour a stout a little bit, like Guinness does, is to add some malt vinegar instead of lactic acid.

Has anyone ever done this? How much for 5 gallons? And when does one add it - to the boil, to the primary, to the "secondary", or to the bottle bucket?

This is interesting. vinegar is acetic acid, which tastes like... well vinegar, so I don't know if that would be a replacement for lactic acid. Where did you hear of this? I pretty certain there would be some taste differences.

dont use vinegar, odds are is still has acetobacter that will happily turn the rest of your hard earned alcohol into vinegar as well.

Okay, that settles that.

I haven't used lactic acid before, either, so I have the same questions - basically, how much and when.

Thanks for the replies.
