Variant India Pale Ale brings peculiar eye-squinting citrus rot tartness (reminiscent of an acidic Berliner Weiss) to the easygoing fore. Brisk yellow grapefruit, orange, tangerine, mango and pineapple tang curiously turns to ‘kettle-soured’ lemony white wine tartness above compost-like sourdough spine. A newly hybridized ‘tart IPA’ that’s truly an acquired taste.
