Notes

Recommended for Imperial IPA, American strong ale, barleywine, high-gravity ale.

Character: Clean and neutral with very high flocculation; tolerates strength.

A clean, very high-flocculating strain that tolerates 12% alcohol, so it is a dry-yeast pick for imperial IPA and American strong ale. Its very high flocculation drops it bright fast; give a big wort enough nutrient so it finishes before it settles out.
