Best For

Pale Ales, IPAs, Blondes, Cream Ales, and any clean American or international lager/pale styles where you want the hops and malt to stay front and center.

Flavor & Behavior

Stays relatively neutral and clean across its normal temperature range. Minimal esters under typical conditions, which is why it’s so popular for American pale ales and IPAs.

It can throw a bit more fruit/ester character if you push it warmer (especially above ~75°F) or drop the pitch rate, but it’s still one of the cleaner American ale strains available in dry form.

Pitching & Rehydration

One 11g sachet is usually enough for a standard 5 gallon batch around 1.050 OG. For best results, rehydrate in 86–95°F water for 15–30 minutes before pitching. Skipping rehydration is the most common reason dry yeast underperforms.

In Practice

This is the yeast we grab when we want something dependable that won’t fight the recipe. Good head retention and finishes dry without needing extra attention.
