On a fine day, you might see Katie Rose absorbing the natural delights in Milwaukee’s Washington Park. It’s a favorite spot of hers, the trees particularly. When you see trees in clusters, gaze up to the branches and you’ll notice an arboreal phenomenon known as Crown Shyness, in which the crowns (or uppermost part) of the trees deliberately do not touch. It’s a real thing, and the inspiration for this cocktail, a summery potion that incorporates products from a couple of local companies – Prairie du Sac’s Wollersheim Winery and Milwaukee’s Heirloom (an offshoot of Bittercube). “The look of it is really striking because it’s just this bright, vibrant green,” she says. “It has lots of beautiful flavors going on. There’s the sweetness from the agave, and the herbal, bitter vibe from the vermouth and the amaro, and [also] tequila as the backbone.” The drink may be named for the coy behavioral trait of trees, but it’s an extrovert through and through.
