Myrcene

Myrcene is a monoterpene and one of the most abundant aroma compounds in hops, cannabis, and bay laurel, contributing herbal, piney, musky, and slightly spicy notes. In NA beer production, myrcene content and preservation are key quality metrics for replicating hop aroma authenticity.

Beta-myrcene (the beverage-relevant form) constitutes 30-70% of the total terpene content in many North American hop varieties, making it the single most abundant terpene in the IPA-style beers that dominate craft beer markets. Its aroma is polarizing: described as herbal, piney, diesel-like, and resinous, it is a fundamental component of the 'green' hop aroma that craft beer consumers associate with freshness and quality. High-myrcene varieties include Citra, Simcoe, and Columbus.

For NA beer production, myrcene presents a specific challenge: it is highly volatile and among the first compounds lost during any heating step. Vacuum distillation and even cold contact at elevated temperatures can strip myrcene preferentially, producing dealcoholized beer that lacks the primary hop aromatic compound. This is why post-dealcoholization dry hopping is particularly important for replicating the character of high-myrcene hop varieties.

Myrcene's solubility in water is low — it is strongly hydrophobic and tends to remain in the foam or on packaging surfaces rather than staying dissolved in the bulk liquid. This physical property makes it challenging to deliver myrcene character in a water-based zero-proof beverage without the solubilizing assistance that ethanol provides in conventional beer. Some producers use hop oil emulsions (oil-in-water emulsions stabilized by lecithin or other food-grade emulsifiers) to improve myrcene delivery in NA formats.

A cannabis connection: myrcene is also among the most abundant terpenes in Cannabis sativa, contributing significantly to the 'earthy' and 'musky' character of many cannabis strains. The terpene chemistry overlap between hops and cannabis (which are botanically related — both belong to the family Cannabaceae) is not coincidental and has led to significant research interest in hops as a source of cannabis-like terpene profiles for CBD-containing zero-proof beverages.
