Spring has sprung, and what better way to celebrate the changing of the clock than by indulging in some oenophile fun?

As part of the 31st annual Russian River Wine Road, 100 wineries will open their doors to the public starting March 13 in a three-day festival full of barrel tastings, chats with winemakers, and chances to explore the stunning Alexander, Dry Creek and Russian River Valley wine regions. Additionally, you'll have the opportunity to purchase limited-edition "futures"--wine that has yet to be bottled and will be picked up 12 to 18 months later--at a discount.

Just don't drink and drive: That's no fun for anyone. In fact, Designated Drivers can pick up an official DD wristband at the first winery visited and get in free for the entire day.

Tickets can be purchased on Friday at any of the vineyards for $30 a head; this will grant you three days worth of barrel tasting fun. Visit the website, www.wineroad.com, to see a full list of participating wineries.
