On tap at Ambulance, pleasantly peculiar sour saison from England gets soaked in French oak red wine barrels with rosy hibiscus flowering, pink peppercorn pep, tart tropical fruiting and mild spelt grains. Light brettanomyces yeast brings out the vinous red grape tannins. Leathery barnyard acridity increases oaken cherry-dried passionfruit, papaya, guava and gooseberry illusions at back end.
