Fermented F1 is a Romulan Genetics cross with a rich, unusual profile that has been described by growers as blueberry-like fruit dipped in gas. Sweet dark fruit can sit against sour, earthy and fuel notes, giving the flower a fermented, funky depth.

Effects are subjective, but reports around this line suggest a substantial, relaxing character alongside a noticeable head change. Individual phenotypes may differ, so its blueberry-and-gas terpene expression is the better defining feature.
