Any oenophiles (wine connoisseurs) here, to comment on varieties which do well when the 100+ degree (F) Texas heat waves start in June? I'll guess there might be a few from southern Spain & northern Africa, but...
Tempranillo
Bad comparison for lotss of reasons, but... the average temps in summer in hill country are only a few degrees higher than in Napa. That said, I love muscadine, which thrives in texas. MD20/20 may have made that a near impossible marketing play lol
