metatartaric acid

[lylo]

I got a pouch of this 2.3 grams metatartaric acid in a Spagnols wine kit but there is no mention of it in the instructions.With a little google research I found out it is to prevent wine diamonds,but I have no idea of when or how to use it!

according to this you add it a week or two before bottling
