"Guaranteed performance" by 8/26, but in reality dry yeast lasts longer.

A clean, modern lager strain from Lallemand. Diamond is often chosen as a reliable alternative to classic strains like W-34/70. It’s known for producing very neutral, crisp lagers with minimal off-flavors when fermented properly.

• Temperature Range: 50–59°F (ideal 52–56°F)
• Alcohol Tolerance: Up to 12% ABV

Flavor & Behavior

Diamond is a very clean fermenter. It produces minimal esters and sulfur, making it well-suited for traditional lager styles. Many brewers find it slightly cleaner or more consistent than older lager strains, especially when fermentation temperatures are well controlled.

It also has high flocculation, so it drops out nicely and helps the beer clear relatively quickly.

In Practice

This is a strong modern option if you want a clean lager without the variability some older strains can show. It sits very close to W-34/70 in character, but some brewers prefer it for its reliability and slightly better flocculation. It’s a safe, no-drama choice for most standard lager styles.

Pitching & Rehydration

One 11g sachet does a standard 5 gallon batch around 1.050 OG. Rehydrate in 86–95°F water for 15–30 minutes before pitching. Cold, consistent fermentation temperatures are key with any lager strain.
