RE: recipe details
grape tannin , is the bitter substance in the peel of grapes.
Red wine contains more from it than white wine, because in white wine
production the peels ( witch may be blue grapes )are not so long in
contact whit the most.
You must be able to find it in stores were they sell stuff for
home-wine & bier makers.
It's a brownish powder.
2) pottasium phosphate
You can find it in the same store as above.
it's a salt, but no;"potassium sulphate" is not the same as "pottasium
I gues one need here the phospor, and not so much the pottasium.
i hope this is a litlle help for you.
