Back before about 1970, Red Mountain jugs didn't say "wine" on them anywhere. The rumor in the industry was that Red Mountain wasn't even made from grapes! At any rate, around 1969 or 70, the jugs started to say "100% grape wine" on them. The statement was true, Red Mountain (whether the 'burgundy' 'chianti' 'chablis' or 'pink chablis') was made from grapes now! All of it from same grape: the "noble" Thompson Seedless, the table grape we all know and love. It makes a fairly innocuous 'commercial' grade of wine, that can be turned into many different things with proper natural flavorings and coloring.
True Story from the a 4th generation CA wine family!
Go up to Mt. Diablo (east of San Francisco) and me an’ Dale would crack open a jug. Yes, we heard the same thing. “Not even from grapes!” We’d put our lips to the jug and count off 40 gulps each. Whew! without stopping .... chug-a-lug.
I got through some pretty lean times with Red Mountain. Even living on $150 a month I could get a gallon a week! *L* Here’s to the “good stuff”!
