In a large pitcher, combine the rosé, tequila, grapefruit and lime juices, agave, sliced grapefruit, strawberries, mint leaves, and limes. Stir with a long-handled spoon. Cover and refrigerate at least an hour, longer if you're able.
If desired, when ready to serve, run a lime or grapefruit wedge around several cocktail glasses. Rim with salt (or sugar!) and divide the sangria amongst cups. Garnish with grapefruit wedges and extra mint, as desired.
Notes
*Storing sangria: I find this sangria gets a bit tart when left for longer than 6 hours. *Agave substitute: Use honey or granulated sugar instead.
