This wonderful local berry is a cross between the Olallie and Chehalem blackberry varietals, and was developed in Marion County, Oregon, in 1956. This liqueur has the best of both berries. It’s sweet, earthy, and reminiscent of summer in the Northwest. Chill and sip as a dessert cordial. Use in cocktails, such as the Bramble, in which Crème de Muir is called for.
