hope you've got some small bottles for that bad boy. No dry hopping? I note your mash is quite stiff. I normally go for ~3 L/Kg as per advice in "brewing Better Beer".. Anyway, it sounds like an awesome recipe, look fwd to trying it.

I Have some small bottles less than a quart somewhere!

Strange when you say about the mash, for me it's quite a wet mash,Ii usually go for 2.1 or 2.2 L/Kg as per advice in the Durden park book...

I must get round to reading Brewing Better Beer by the looks of it as I have in my head that the wetter the mash the more the enzymes are just 'floating about' between the crushed grains doing nothing rather than utilised.

I may well dry hop this with citra and or columbus, my thoughts had'nt got that far!

I have had a but of a problem with the smack pack, it was rather puffed up so smacked it several times, it did not seem to puff up any more when I opened it I had ruptured the yeast sac but not the nutrient one, just pitched it anyway looks like it may need a little rousing to get it to start, I have So5 in the fridge just in case!

If mash wetness had a large impact, brew in a bag wouldn't work e.g. 4.5Kg grain in 34l liquor = 7.5 ratio.

yeah....tthats a myth, and Phil Lowry touted it in beer magazine recently. The enzymes are mostly in the grains.

The liquor to grist ratio has some effects on the fermentability of the wort. Increasing the ratio has a similar effect to increasing the mash temperature, as you head much beyond 2:1 there is a distinct drop off in fermentability. I hope the enzymes get out of the grains or those adjuncts aren't going to get converted!

You would certainly want to keep to the parameters given in a recipe if you want to duplicate it, otherwise there is little practical reason to exceed 2.5:1.

For BIAB, if mashed at 66C there must be some reduced fermetability, whether it's significant or if it can be mitigated by lowering the mash temperature I'm not sure.

I stick to 2.2:1 and manipulate fermentability by changing the mash temperature :)
