Lactic Fantastic Guava from De Kromme Haring is a kettle-soured sour ale built around guava fruit. The base beer was infected pre-boil with Lactobacillus and fermented with the brewery's house blend, which includes Brettanomyces. The result is a refreshing beer balancing tropical fruit character with tartness from wild fermentation and a gentle hop bitterness.

High carbonation adds a crisp, lively texture. The nose presents lemon zest, peach and floral notes alongside the guava. At 4% ABV, this is a sessionable sour designed for extended enjoyment rather than intensity.
