SafBrew HA-18 Yeast

Brew bold, high-gravity beers with SafBrew HA-18 Yeast, a specialized yeast and enzyme blend designed for extreme fermentation conditions. This 25 g format supports batches up to 5 gallons and enables alcohol levels up to 18% ABV, delivering dry, powerful beers with depth and complexity even under high sugar and heat stress.

SafBrew HA-18 is intended for brewers producing strong ales, barleywines, and barrel-aged styles where full attenuation and fermentation reliability are critical. The integrated enzyme system enhances fermentability, allowing the yeast to process complex sugars efficiently and complete fermentation in high-gravity worts.

This strain delivers very high attenuation in the range of approximately 98 to 102 percent and performs best within a warm fermentation temperature range of 77 to 95 degrees Fahrenheit. It is thermotolerant and resistant to osmotic pressure, supporting consistent performance in demanding brewing environments.

For best results, rehydrate the yeast according to manufacturer recommendations before pitching. Adequate oxygenation and yeast nutrient use are recommended, particularly for high-gravity fermentations, to support healthy yeast activity and complete attenuation.

Produced to professional brewing standards, SafBrew HA-18 Yeast provides a dependable solution for brewers seeking controlled, high-performance fermentation for strong and specialty beer styles.
