Pumpkin Sage Pimm's Cup

"Guys, I'm hosting some friends this weekend, which means that mixing up one cocktail at a time just isn't gonna cut it. With an eye towards the holidays coming up, I'm going to start posting some pitcher and punch drinks, so you don't have to measure and shake your arms off during a party (unless the shaking is part of a dance move, which is highly encouraged). First up is the pitcher version of one of my favorite cocktails so far this fall, the! It's not the sweet spiced pumpkin drink you're probably used to -- it's tangy and herbal and jammy and VERY refreshing."
