I wondered if anyone who has used the above yeast can give me an idea on the quantity required. I am brewing a fairly high SG IPA (somewhere in the region of 1.065-1.080) batch size 15-20L.
Brewers friend recipe calculator suggests 27g of this yeast based on a 10 billion cells/g density. This is rated at > 6 billion cells/g (which, if i'm calculating correctly, based on the lower estimate of 6 billion cells/g, I would actually need 45g, or 4 packets!!).
I have also seen posts which suggest that 1 packet of this yeast would be ample for a batch this size up to an SG of 1.085?
Any advice would be greatly appreciated as I don't want to under of over yeast!
In case this is needed, I am trying a very basic recipe out (I'm still a newbie);
2-2.5 kg pre-hopped light DME 0.5-1.0 kg dextrose Fermentis US-05 yeast ? g 50-75g Cascade (dry hop) 50-75g Southern Star (dry hop)
Thanks in advance! Gary
