SafBrew HA-18 Yeast

$11.99
SafBrew HA-18 Yeast is an advanced yeast and enzyme blend engineered for brewing very high-gravity beers. Its exceptional attenuation, thermotolerance, and ability to ferment complex sugars make it ideal for producing strong ales, barleywines, and barrel-aged beers with high alcohol content.
  • Specialized yeast and enzyme blend
  • Designed for very high-gravity brewing
  • 25g packet treats approximately 5 gallons
Fermentation Temp Range
Each yeast strain has a temperature range where it performs best. Lagers require cooler temps, while Kveik yeasts can ferment in extreme heat. Maintaining the proper fermentation temperature for each yeast strain is crucial its health. Matching a yeast's ideal range to your environment (or your ability to control temp) is key to getting clean, consistent results.
Scale from 30°-120°F

SafBrew HA-18 is formulated specifically for very high-gravity fermentations where maximum attenuation and alcohol production are critical. Its integrated enzyme blend allows the yeast to ferment complex sugars that traditional brewing yeast cannot fully utilize.

The strain performs best between 77–95°F (25–35°C), offering excellent thermotolerance and resistance to osmotic pressure while producing highly fermentable wort for strong beer styles.
