Bulldog B4 English ale yeast

[bitter_dave]

Hi All,

Anybody tried Bulldog B4 ale yeast? It sounds like it might make quite a nice full-bodied bitter - attenuation 65-70% with high floculation (apparently).

Anybody tried this or had any views?

Was thinking of making a bitter of around 1040 gravity with a simple grain bill of something like 95% pale 5% crystal (or maybe a tiny bit more crystal).

The Bulldog range seems to track Mangrove Jack pretty closely, so as a first assumption you might want to compare B4 to MJ's main British yeast, M15. Or it could be just repacked S-04 or something.

Thanks for the suggestion Northern Brewer.

According to the description B4 seems to attenuate a bit less than M15 (65-70% versus 70-75%); S-04 has generally got about 75% attenuation when I've used it in a standard bitter.

I would not be at all surprised if it were repacked something else though!

With you, thought you were saying the other way round. But you should take some of those numbers with a bit of a pinch of salt - it can depend on the exact conditions you measure attenuation under.

But a dry British yeast with 65-70% attenuation sounds like Windsor/S-33 or Danstar ESB? In which case it will drop well but still be quite powdery, technically Windsor doesn't flocc well even though it drops well.
