The original post asked about clubs and allocations participated in.
As for clubs, I am in Villa Creek's Club, which is a Paso Robles winery. Also a small winery, but the owner does several interesting blends. His James Berry "High Road" is my personal favorite. It is 40% syrah, 40% grenache, and 20% mourvedre. Very rich. Lots of flavor but not heavy, if that makes sense. They also have a very nice blend they call "Avenger" which is 60% syrah, 30% mourvedre, and 10% grenache. More complex, in my opinion. We had a great afternoon hanging out with the owner 10 or so years ago (we were the only guests that afternoon) and went ahead and did the club and we still enjoy seeing it arrive.
We're also members of Tobin James' club, also a Paso Robles winery. Also a great fun afternoon there, the reason we're in the club, but we definitely enjoy their wines.. We especially like their "Fat Boy" zinfandel. Very full bodied.
We've been to Napa a half dozen times or so, and that's still our preferred place to go (possibly more for the food) but the wineries in Paso Robles are much more relaxed and more fun.
As for allocations, I really like Vincent Arroyo's petite syrah and typically take a case in their annual allocation. It's a small winery on the north end of Napa Valley, on the north side of Calistoga. Very little retail distribution, as almost all goes on the initial allocation. It's a good place for a tour if you're in Napa Valley. It's not fancy at all, but the staff is very laid back and loves the work and the product.
