Several years ago, I think it was 2003 or 2004, we went to an herb farm in Paso Robles. It had a winery adjacent to it (I remember the wine being mediocre), but wonderful herbs. The potted plants that I bought there were some of the best herbs I ever bought.
I recall this place being on the south side of 46w, not that far past Castoro. However, I can't seem to find any information on it. None of the winery names on the map ring a bell, but it may have changed names. Is this place still there? I would love to go back on our visit next weekend.
