The attached chart gives the degrees brix, titratable acidity, and pH of several varieties sampled on 9/4/02. Last week, we had a little trouble with the instruments in the lab and some of our numbers were a little out of whack. We think we have solved the problem in the lab and the data looks more reasonable.
