Pétillant Natural, affectionately known as Pét Nat, is a natural sparkling wine that could be considered Champagne’s wayfaring big brother—it’s older, wilder, more interesting, and on Sunday, July 15th, Loyal Nine is throwing a party celebrating the stuff. What better way to spend a summer evening than a fling in the garden with sun, snacks, and bottomless bubbles? Get to Cambridge between 6:00 and 9:00pm, where you’ll be joined on the patio by Oscar from Olmstead Wine and Matt from SelectioNaturel, ready to pop corks and drop knowledge while you sip, snack, and mingle. With puppies! Dogs are invited too. Tickets are $55 including passed apps and all of the bubbles (seriously, free refills). Snag your spot here.
