If you’re going to take care in purchasing the highest quality, ethically raised meat, you’ll want to make the same effort selecting the wines with which to drink it.
So where to start? Simple: find a good retailer and ask the same questions you’re asking about the meat you buy. Where is the wine from? How are the grapes farmed? Is anything added in the winery? You’ll discover that not all wines are made naturally, regardless of price or status, which should be of concern to any ethically conscious eater and drinker.
