With Oktoberfest in full swing, all eyes are on beer this fall—including those of some top mixologists. Beer might not be the first ingredient you think to mix with finely-crafted spirits, but it offers a stunning diversity of flavors as a mixer, as this unique cocktail highlights. Start with 1.5 ounces of Highland Harvest Scotch. Add 4 ounces of a Belgian-style white ale of your choosing—we suggest Crazy Mountain Lava Lake Wit. Squeeze in the juice of a fresh organic lemon wedge. Stir gently and serve in a lowball glass with a sprig of fresh basil.
