When harvest is on in the Napa Valley, vineyard and winery workers don't have time to do much else — and that includes shaving.
The annual proliferation of "harvest beards" has inspired the Napa Valley Vintners, a trade group representing more than 400 wineries in Napa County, to create a formal contest.
More than two dozen beard photos have been entered in the contest at napavintners.blogspot.com, where you can click through the gallery and vote for your favorite through Halloween.
Voting is also underway through Oct. 31 on the Vintners' Facebook page, facebook.com/NapaVintners.
Do you have a harvest beard? The Vintners' contest is closed, but you can still share a snapshot with us! Just click the upload button.
