With all the discussion about fruit juice sugar contents and stuff going on around here, especially for the mead calculator, I thought I should post this link for you all. This is a link to the USDA Nutrient Data Laboratory site, particularly the nutrient search on their database. ie. if someone like me wants to know the "standard reference value" of sugars in a can of Blackberry-Apple fruit juice bland, i can look it up on there and find it.. they list a ton of info for each product, though the search catagories are a tad awkward for those of us who don't speak the commercial speak.
anyhow,hope that helps someone..
