Drink By This is part of Wet February, a series about America’s increasingly muddled relationship with drinking—and how to sip your way through it wisely and well. I’ve had the same encounter multiple times, but I remember one instance vividly. I had finally spotted a canned version of the Penicillin cocktail, by the brand Tip Top, on the counter at my local wine shop. “I’ve been looking for this one,” I told the store clerk. It had been sold out on Tip Top’s website ever since it was released.
