Beg to differ. The oldest part of that vineyard is, like many of the old vineyards in that neck of the woods, a field blend that contains zinfandel, carignane, petite sirah and grenache. LS may not have disclosed that on the label (I don’t remember) but it was never 100% zinfandel.
I had a '77 or '78 Lytton Springs from Lytton Springs in Vegas at In-N-Out Burger courtesy of Timko or Bob Summers…don’t remember which…but it was labeled as Zinfandel.
Geez . . . why do I always have to school you children? The wine only needed to be 75% zinfandel to be labeled that way and the rest could have been anything, though it was most likely the carignane and petite sirah in the original vineyard. The 75% rule still applies today as I recall . . . but my senior moments are becoming more frequent.
Frankly, the old field blend wines have always been among my favorites.
No, you’re right - for Calif it’s 75%. And that pesky Ridge just slipped by 2%. I used to really dig field blends, but less so now. OTOH, I suppose we could easily call lots of stuff a field blend.
