I really like Nottingham yeast compared to most others, I have now made several brews using this yeast and its fantastic. Lag time is usually less than 10 hrs sometimes as fast as 3 hrs. I ferment this yeast in WW at 25 degrees to maximise and reduce fermentation time. Usually fermentation in complete in 50-60 hours from pitching yeast. I have not experienced any off flavours and the brews tastes fabulous. I have now adopted this as my main yeast for ales, I’m still experimenting with lager yeasts to find one I really like. I have used MJ M54 California Lager before with really good results.
If you have experiences using Nottingham good and bad I would really like to hear about them.
