I've been enjoying a Louis Jadot pouilly-fuisse this afternoon. Cool and crisp and tart. It's my go to summer afternoon wine.
Scout's Honor, 2011 - bold red blend, primarily zinfandel, strong tobacco finish.
I too enjoy the taste of a good Chardonnay on a warm summer evening. I typically drink Chards from California, as they're reasonably priced, and one of the few wines from California that don't taste like charcoal. La Crema Chardonnay is my go-to...what I call a "Tuesday-night wine". Huntington makes a good sittin-on-the-porch Chard, and I also like Chateau St. Michelle from Washington, thought it's not nearly as buttery and smooth as the La Crema.
