You gotta love a free event and this weekend there are no fewer than three good ones. Each present an opportunity for you to reacquaint yourself with a San Francisco original.

Crushpad is do-it-yourself (with a lot of help) winery. Designed for non-traditional winemakers you work hand-in-hand with Crushpad staff and consulting winemakers to define and create your very own wine. You can choose from among their excellent grape sources or identify your own. The end result is a world class wine with your own brand. Custom Wine customers are encouraged to visit Crushpad frequently and actively participate to gain the full experience – education is a key part of Crushpad.

Cost varies depending upon vineyard with most barrels (25 cases) ranging from $5700 to $10,900 ($36/bottle).
