The only hints I found so far are on that link, where they state, "Primary fermentation was intercepted with white wine yeast and Kendell's fruit juice to parlay the beer's apple lolly nose. Twanging Fuji, Granny Smith and Pink Lady tartness is lifted from the Belgian-influenced Saison yeast."
I am not even sure what malts to try here...this is going to be real hit and miss. Oh well, I am guessing Wyeast 3724 would be a good start, maybe pre-ferment some apple juice with wine yeast, and add it into the primary with the malts after about three days.
I personally because of BIAB use a very thin mash, probably pretty close to a 4:1 ratio water to grain...
I believe mr JoKing and Mike are using around a 2.5:1 with exceptionally good results! I think I recall Jo telling me that was his favourite Liquor to grist ratio but may have my numbers slightly off...
We've been discussing the North Welly Porter being brewed Sunday, using a collection of equipment and brewing ideas.
Think we're settled on a batch sparge - Matthew & I both batch anyway ?
But I usually mash thick - 2.75:1 and mash out and Matthew mashes thin 3.5:1 or more
We both get good results on our systems, we just need to figure out what we do for this collaboration
