For anyone who may want something celebratory, I got an e-mail from the Wine Attic in Clifton saying they have some Nats championship sparkling wine on sale. See link below. The store is in the town of Clifton just south of the railroad crossing. I have no affiliation with it other than having been a satisfied customer several times since we discovered the store this summer, but I figured it was reasonable to promote this particular item on this particular forum!
