Yes, it is that most wonderful time of the year, National Sangria Day! And since that coincides with the Holiday season through some weird coincidence, Cava Sangria would be excellent as a holiday punch.
Here is a good basic recipe for Cava Sangria:
8 oz. Fresh Squeezed Orange Juice (or good Tropicana not from concentrate)
A Generous shot of gin (if you have it, a nice citrusy one like Leopold’s)
A Generous shot of vodka
A bottle of Cava (which is a sparkling Spanish white wine-Spanish champagne as it were)
3 Tablespoons sugar or 4 of simple syrup (more or less according to your sweet tooth)
A double shot of Gran Marnier
Mix everything except the Cava and refrigerate for up to 24 hours. Just before serving add ice and then the Cava. Serve cold over ice. Refreshing and invigorating until glass #4, then not so much.
