Not Windsor but Wyeast 1968 at higher temps for more esters and dominates the kit flavor.
Day 1 April 28, 2011 - Dark Ale kit + Mexican Cerveza kit to 24L OG=1.044, washed wyeast 1968 yeast. Pitched at 70F, brewed warmer 71-73F, Day 17 May 14, 2011 bottled FG=1.012 = 4.12% alc = 72.73% attenuation = 24.28L. Added 66 grams white sugar to bulk prime. Tastes very British like and bitter like EB, does not have the chocolate flavors anticipated so need to use a more neutral yeast for the dark ale kit like the Coopers Ale kit yeast. Had one tonight and getting some British mineral water flavors, nice aromas and color.
Next time for a chocolaty brown ale will use the neutral kit yeast as we make enough other British beers with 1968 or 1028.
