The "brut" style means fermented until no residual sugar remains, giving it a bone-dry finish that sits closer to sparkling wine territory than a conventional IPA. IMPOSSIBREW released this as a fifth anniversary limited edition with only 1,000 ten-packs, using the same cryogenic low-temperature fermentation as their core range so there's no dealcoholisation step. The Social Blend here includes L-theanine, ashwagandha, and magnesium. In the glass it pours hazy gold. The carbonation is noticeably lively, genuinely sparkling in a way most AF beers aren't. Tropical hops lead on the nose and palate, tangerine and a soft white grape note underneath, and the complete absence of sweetness sharpens everything up. There's a faint biscuit malt base but it doesn't get in the way. The dry finish lingers clean. At 17 calories per 100ml with zero sugar it's one of the leaner options in the AF IPA category. Whether it stays available beyond the limited run is unclear.
