Wyeast 1945 NB NeoBritannia
This traditional English ale strain works well for a wide range of beer styles, from low-gravity bitters and milds to strong stouts, porters, and old ales. Due to the cells’ chain-forming characteristics, it is an excellent top-cropping yeast. Moderate ester profile makes it a great match for hop-driven beers like bitter and pale ale, but attenuative enough to handle higher-gravity malty styles. Excellent flocculation yields clear beer and allows for cask-conditioning. Ferment at the lower end of the temperature range for a cleaner finish, or utilize the upper end to enhance low-gravity beers with a more assertive ester profile. Apparent attenuation: 72-77%. Flocculation: medium-high. Optimum temp: 66°-74° F.
