YouTube lets you post videos you've created (for free). As you can see from this one, the production values need not be "broadcast quality." But if you're someone interested in how Stormhoek thinks about their wines, you'll be more than willing to sit through this seven-minute video, despite its flaws.
So, take the handycam along the next time people tour your winery, and film a minute or two of the tour guide (hopefully the cute, engaging one). Post it on YouTube, see what happens. If you're really daring (heavens!) you'll add a little voice over at the end with a special offer (free shipping?) for people who watch the video all the way through. And then come back and let us know what happened.
