As a wine guy in the retail business, I get a lot of regular customers from various wine clubs that come around looking for suggestions. These people get together usually once a month and they each bring a bottle of wine and, sometimes, food to pair it with. Generally the cap limit is $15 a bottle.
They’re not only looking for suggestions and pairings to fit a theme, but whoever is hosting that month might be looking for a theme itself. It could be a region or part of the world. Northwestern United States is always a big hit, because Oregon and Washington produce great affordable wine and cover a bunch of different grapes and styles. One person is designated an Oregon Pinot Gris, another a Washington Merlot, etc etc. Or it could be different California red blends. Or it could be just one varietal from around the world, which is exactly where I’m going with this.
One theme that is always a smash hit, where everybody has the most fun and learns the most about wine, is Sauvignon Blanc from around the world. Every time I suggest it to those who haven’t done it yet, they come back raving about the results.
