The Winter Caipirinha (pronounced kai-pe-REEN-ya) is a modern cocktail of unknown origin that was published by Leblon Cachaça, a Brazilian brand of rum. It's a cold-weather variation of the classic Caipirinha, the official drink of Brazil, and it calls for the original's cachaça, simple syrup, and lime template but pairs them with açai berry liqueur, cranberries, and rosemary, adding a unique bitterness to the already tart drink.
Cut lime into three wedges.
Add lime wedges pulp side up, six cranberries, and one rosemary sprig to a shaker.
Using a muddler, gently muddle cranberries and rosemary sprig in lime slices for 5-7 seconds.
Add cachaça and açaí liqueur to shaker.
Fill shaker with cubed ice.
Shake for 10-20 seconds.
Remove rosemary sprig, then pour into a lowball glass.
Garnish with remaining three cranberries and two rosemary sprigs.
