It’s official: wheat beer summer is in full swing, and sales for Hefeweizen, Witbier, and Belgian yeast strains are up a whopping 40% in 2026.
But these styles require a masterfully delicate touch. In this episode, Mark and Richard tackle the "Holy Trinity" of wheat beer flavour drivers—Citrus, Banana, and Clove—and show you how to move past guesswork to orchestrate absolute balance in the cellar.
Whether you want to drop an intentional banana bomb or keep your Witbier's crisp citrus notes from being buried under a mountain of heavy phenols, we break down the precise chemical and process levers you need to pull.
In this episode, we unpack:
The Isoamyl Acetate Equation: The exact relationship between glucose, leucine (FAN), and the metabolic flux that drives classic banana esters.
The Bio-Citrus Route: How to leverage the biotransformation of geraniol-rich hops rather than just leaning on orange peel additions.
Universal Ester Levers: How underpitching by 10–20%, raising temperatures, and restricting oxygen alter your ester-to-phenol ratios.
Temperature Suppression: Why keeping things cool (17–18°C) is actually the best way to let delicate citrus profiles shine.
