Bingo. Wine lovers that become "connected" or invested in a brand will buy more wine, become ambassaders for the brand, and sell wine. If you are a winery and want to create more such people attached to your brand, blogging is a very good way to do this.

The blog format allows this in a way that a static website alone cannot.
