The Scots Pine may be one of the few cocktails at The Aviary that you can easily recreate at home, but it's by no means run-of-the-mill. True to form, the drink is a medley of surprising flavors and textures, courtesy of aged tequila, St-Germain, yuzu, grapefruit and Alba Scots Pine Ale, a Scottish beer made with pickled pine and spruce shoots.

1½ ounces reposado tequila, preferably Fortaleza Tequila Reposado
¼ ounce St-Germain elderflower liqueur
⅓ ounce yuzu juice (bottled is fine)
¾ ounce fresh grapefruit juice
½ ounce simple syrup (1:1 ratio)
1 egg white
Ice
Alba Scots Pine Ale

In a cocktail shaker, combine the tequila, St-Germain, yuzu juice, grapefruit juice, simple syrup and egg white. Shake for ten seconds. Add ice to fill and shake for another ten seconds. Strain into a rocks glass. Top with Alba Scots Pine Ale. Serve.
