Well I'll say this, good Pinot Noir vineyards in the Santa Cruz Mountains having waiting lists. Kevin Harvey and Pax Mahle are on my waiting list, so imagine where a home winemaking club would be on the list.
There are a few vineyards offering 'come pick em' grapes right now. The grapes are ususally of shocking low quality.
I bet I know the club being referenced here, it is tied to a commercial winery and a commercial vineyard management company. Personally, I'd ask for the grapes at 24-25 BRIX. 22 is too low for the East Penninsula where these grapes are likely to come from.
