i recall italian and austrian antifreeze into wine scandles. there was the burgundy mix sugar and water plus a couple other things to make good wine. the most recent i know of, a group of growers or negoatiants sold grapes(juice) to gallo that they used to produce their french pinot noir. the frenchies were caught, as very little pinot grew in the district from which the juice was sold. as far as i know, no one ever complained that the wine did not taste like pinot. wine spectator gave the wine pretty consistent 88's as i recall. gallo was happy with the arrangement, as their landed price for the juice was around 1 euro per 10 liters(or some such), and the wine brought $10 a bottle.
