Here's a 75-second "videoblog" of winemaker Tony Coturri (Flash player required - you'll need to press the Play icon -- it doesn't start automatically).
The quality is abysmal (lots of background noise, grainy/small video, unreadable titles). On the other hand, it's short and reasonably interesting. If you were promoting a event, doing this sort of video before the event (and linked to your e-mail/print promotion efforts) could signficantly increase interest and attendance (if done with somewhat higher production values).
Here's a higher-quality video of Tony Coturri from Wine Library TV: Episode 35 - Tony Coturri (QuickTime required).
What's interesting about this second example is that people who own Video iPods can subscribe to Wine Library TV episodes (free) and have them automatically downloaded and synched with their iPods.
Forward thinking wine marketers should be experimenting with video. It needn't be expensive, and if it tells an interesting story, your fans are very likely to pass it along to others.
Why Tony? I don't know. This whole post started because of a press release from Counter Vegetarian Restaurant which mentioned "videoblogs of organic wines."
