Ive been brewing for a few years now (mostly AG but some kits) and have ventured into the world of wines, mainly because when my granddad past away (over 20 years ago) I kept all his stuff. I have a ton of books, some quite old (40-50 plus years old?) What strikes me is that recipes for the same wines that you find on google/forums etc seem to differ from the books. Just wondered if any of you experienced wine makers had noticed changes in the ingredients, amounts, chemicals used etc. Just thought it would be interesting. Thanks!
