Beer Faults Series: MBT - Lightstruck
Product Description
MBT (3‑methyl‑2‑butene‑1‑thiol), commonly known as the “lightstruck” fault, occurs when beer is exposed to ultraviolet light, causing hop‑derived compounds to break down and form a skunky, sulfur‑like aroma. This off‑flavor can develop within minutes of light exposure and is irreversible, making prevention through light‑protective packaging and proper storage essential.
