Does anyone on these forums do or have experience with BIAB all grain partial boils?
I have been doing BIAB Partial mashes for a few months now, and last night I came to the realisation that I could probably ditch the tin of extract that I have been including in each brew, and just up the grain bill.
I only have a 20L(ish) brew pot so I have been doing partial boil partial mashes anyway, using the BrewPal iPhone app to great success (not sure how accurate my calculations are but the beer is tasting good and pretty much what I'm aiming for each time). Typically my grain bill is around 2-3kg (plus a 1.5kg tin of Brewpacks Pale Malt Extract). I use however much strike water the app tells me to mash with. plus as much as I can to dunk sparge the bag afterwards (I have a 7.5L pot which I use for the sparge water, poured into my fermenter to dunk the grain bag in - not ideal but it seems to do the trick). I boil whatever amount of wort I end up with, plus the extract, then top up with water to 23L in the fermenter.
My efficiency seems to be surprisingly high (consistently high 80%s), and I have got to a stage where the BrewPal app is getting the OG pretty much bang on, after several settings tweaks.
So... bearing my method and equipment in mind, am I right in thinking there would be little difference to my technique if I simply upped the grain bill, upped the strike water, and cut the extract out? I suppose the main issue would be that the calculations I were previously using would be somewhat irrelevant?
I know there will obviously be some trial and error in this, so I was thinking of doing a very simple Pale Ale recipe so that I can easier judge what needs tweaking. Something along the lines of this:
23L
4kg Maris Otter
0.25kg Torrified Wheat
25g First Gold (9.8%) 60 mins
15g First Gold 15 mins
10g First Gold 10 mins
10g First Gold 5 mins
Dry hopped with 35g First Gold
Safale S-04
Using BrewPal based on 80% efficiency, im estimating around about 1.047 OG, ~40 IBU. I would expect any deviance either way on the OG should not be too detrimental to the balance of the beer. Does this seem about right (especially to anyone with prior experience of this technique)?
Any advice would be greatly appreciated.
