I am working on some wine-related research for a new project this week and have been taking a look at a number of sites from California's famed Napa wine country. Surprise! They are using video.
V. Sattui, one of the more commercial, touristy vineyards (the wines are not great, but the picnicing is, since V. Sattui has cheeses and foods for sale in its onsite wine store) has a whole series on their web site. I recommend checking them out on their own site to see how they're displayed.

Secondly, I was at the Wine Sustainablity site, a program that helps the wine industry learn about sustainability and best practices for growing grapes and making wine. Even they have a lovely and helpful intro video.
