Our favorites from the last April in Carneros included:
Acacia:
Well-preserved ladies wearing lots of gold pour the tastings. Nice single-vineyard pinots and chardonnays. We didn't taste any of the brut stuff, but it looked good. Ended up picking up an interesting Viogner and a Pinot Magnum at (relative) bargain prices. They have a decent picnic area with bocce court and horseshoes. We'll hit that joint again as part of a bike ride through the vineyards.
Bouchaine
Totally casual tasting experience. This was one of the most fun stops on the trip. Their wines lack the wow-factor of some of the other stops of the day, but their Syrah stands up pretty well. Most of their grapes are from their property or sourced from very close by. We picked up a Pinot Meuniere which I hadn't tasted before. Also picked up a late-harvest Chardonnay dessert wine that was like golden sunshine in our mouths. Worth a visit with the picnic next time.
Etude
Could be called Att-etude for some of the comments of the lady who did our tasting. We had lunch on their patio which was great. They seem to be in transition in their tasting area. We tasted in an area that looked like it was set up as cubicles which was a little weird. They pour their Etude label as well as a label called Fortitude. We tasted both. Fortitude wines were sourced from multi-generational single-family growers in the area: neat idea. We (ok, I) didn't dig the wines too much though. Etude wines are very refined, almost French: super balanced, plenty of mineral notes amongst the fruit. This was the only place we tasted Cabs and they REALLY stood out amongst the rest of the tastings. Especially Etude's St. Helena Cabernet Sauvignon: wow, what a great wine. >$100 a bottle at the vineyard was almost worth it too (for a cheapskate like me). We'll go back there once they straighten out their tasting situation.
Ceja:
Lots of fun. This is a Mexican immigrant family-owned vineyard. They're very proud about their story and will tell it to you 3 or 4 times in the course of a tasting. Standouts were: Sauvignon Blanc was great. Pinot Noir was amazing. Really nice Merlot too. The rest was really really good. Good acidity across all their varietals emphasized the bright notes. The grounds were really nice too. Bocce ball court, lots of shaded patio areas to sit and enjoy the day. Worth a visit. Maybe even worth joining the club.
