This blog consists of pieces on various wine technology topics. These are sorted into Categories: Postmodern Winemaking, Natural Winemaking, Terroir, Alcohol Adjustment, Social Responsibility, and so forth. The Search function will bring up titles discussing your keyword: sulfites, micro-oxygenation, chips, allergens, fining, and reverse osmosis are rich in content. I also recommend the Postmodern Winemaking Calendar Mandala or the the Postmodern Winemaking Glossary which ties all the concepts of postmodern winemaking together.
Apropos of nothing, I just had to repost this item off Jancis Robinson's blog commenting on her article about Canadian wines. It's among the funniest things I ever heard.
From Valerie d'E Miller, Millers Landing, Ontario:
Thank you for an excellent article on the Canadian wine scene. We have a small vineyard in Canada and have found the whole situation mighty frustrating. You covered it beautifully.
