The drive up the mountain can be harrowing, so allow plenty of time. The reception at the winery can be no less than frigid if you have not done your homework and made a reservation confirmed by email well in advance of your arrival. Cain is not a winery on the "party bus" tour of Napa.
On Wednesdays from 5:30 – 9:00, the winemaker pours Jeff’s three selections as well as a bonus pour of his choosing that might be a barrel sample, a reserve or library wine. Four 3 ounce pours will cost you $18. Add three tapas paired to the wines and the cost is $28. In my book that’s a hell of a bargain.
