What's hoppy, sour and tropical all in the same sip? Our surprisingly sessionable Hop Tart . This easy drinker blends Belgian Pale malt from the Colorado Malting Company with biting lactobacillus for a slight hint at sourness that propels bursts of passion fruit, guava and pineapple courtesy of hefty Nelson Sauvin, Galaxy and Experimental Hop 522 dry-hopping. This Hop Kitchen release delivers a new spin on the American sour ale.
