When fermented at the correct temperature, Empire Ale yeast exhibits extremely
characterful and appetizing estery aromas reminiscent of rich dark fruit.
This yeast strain has been carefully selected to aid mouthfeel in the finished beer.
Body should be full leaning towards a rich dark fruit character. Care must be taken when
designing the beer to adjust hop bitterness to alleviate an over sweet finished beer.
HIGHER ALCOHOL BEERS:
Higher alcohol beers will tend to be slightly too sweet and heavy due to the moderate
attenuative capabilities of the strain although a lower mash temperature may help the
fermentability and lower the final gravity.
