Omega OYL-405 Helio Gazer

What the manufacturer says

With enhanced Thiolized capabilities, Helio Gazer boosts thiol biotransformation to free thiols 200x above sensory threshold, creating a supernova of tropical, passion fruit flavors and aromas; the current page states 'Where Cosmic Punch complements, Helio Gazer dominates.'

What the evidence says

• Omega markets Helio Gazer as boosting free thiols to around two hundred times the sensory threshold; those are concentration claims in finished beer, not conversion yields. Omega Yeast, Helio Gazer
• In Omega's own published figures Helio Gazer reaches 6,000+ ppt of 3SH, against about 600 ppt for Cosmic Punch, which shares the same British V parent. That is about ten times or more in Omega's published figures. Both are rated High on this site's three-step scale; the scale does not show that gap. Omega Yeast, Top Crop experiment

Rating context: manufacturers usually quote free-thiol concentration relative to the sensory threshold, not conversion yield. Peer-reviewed work finds that only a small fraction of bound precursors is converted in beer fermentation, so the ordering between strains is more reliable than any absolute number Chenot et al. 2021 Michel et al. 2019.

In practice

Easy to overshoot. Treat precursor-rich hops and Phantasm as a dial, not a default, and manage oxygen strictly.

Hops that reward this strain

Citra, Cryo Citra, Cryo Mosaic, Cryo Simcoe, Ekuanot, Galaxy, Hallertau Blanc, Kohatu, Mosaic, Nelson Sauvin, Riwaka, Sabro, Simcoe, Strata, Superdelic, Talus, Vista, Waimea. Each carries a high rating for bound 3MH-family or 4MMP precursors. Mash and whirlpool additions supply precursors during fermentation; a cold dry hop mostly adds the free fraction.
