Rich,
Life is interesting. Somehow many of the things one experiences and witnesses do not make any sense at the time but as one ages, it all begins to make more sense. I am 69 butwhen I was about 6 or 7 and making wine with my Father and Grandfather, I remember going with them to the produce yards in Pittsburgh to buy California grapes. My Grandfather made all the selections and we would buy Muscat and a red grape to complement it in a ratio of 1 white to 3 red. We would buy enough grapes for from 2 to 6 barrels, depending on existing inventory and cash on hand.
The reds were either Alicante or Zinfandel. Our job, as children, was to strip the grapes from the stems prior to crushing. The kids (and there were a bunch of us, brothers and cousins) preferred the Zinfandel because they were larger and easier to strip. My Grandfather, on the other hand, all other things being equal, would buy the Alicante for a number of reasons, including the price, quality and sweetness. They were much smaller and harder to strip. I did not understand why he would do this until I read your reply, above. The ratio of skin area to volume was higher and it must have made a better wine. I am not sure my Grandfather knew why it made a better wine, other than from experience.
Thank you for the information. It was a better answer than what we used to get from our Grandfather. When we'd say, "Poppy, why are you buying the Alicante rather than the Zinfandel?" Because at that time children were to be seen and not heard, he would reply, "'Atsa why!"
