Imperial Yeast: A07 Flagship

Commonly referred to as “chico” this yeast is a craft brewing standard, loved for its extremely clean character.

This strain performs well at standard ale temperatures but can be used in the low 60s to produce exceptionally crisp ales. Flocculation is in the middle of the road and will typically require filtration or fining to achieve crystal clear beers.

• TEMP: 60–72F (16–22C)
• FLOCCULATION: MED-LOW
• ATTENUATION: 73–77%
• ALCOHOL TOLERANCE: 12%

Suggested Substitutions*:

• Fermentis: Safale US-05

• Wyeast: 1056 – American Ale

*Suggested yeast substitutions may not be an exact replacement, but they will be a very close approximation.
