Plans for 2nd BIAB

Post #1 made 15 years ago
by oz11
Attempting to replicate an extract brew I did last year for a comparison. Initially I thought I'd try a stout, but have changed my mind for a best bitter type ale.
The extract recipe was:
Brew Length 23L
2.5kg light spraymalt
400g crystal

Target 10g (60 min)
Northdown 10g (60 min)
Challenger 11g (60 min)
Northdown 10g (15 min)

Also dry hopped with 15g Target.
(I know some people are :nup: with target, but I like it!)

OG was 1042.

Is there enough info here to scale down to a 10L mini-biab?
I am thinking replace 2.5kg spray malt with 3.6kg pale ale malt (2.5kg/0.7 = 3.57kg taking an estimated figure of 70% mash efficiency and rounding up).
For a 23L all grain brew this would give a grain bill of
3600g pale ale malt (90%)
400g crystal (10%).

Popping my requirements into the calculator gives me a required grain bill of 2463g, so my 10L biab grain bill looks like:
2217g pale
246g crystal.

I may increase this a little bit while I am getting to know my bag and equipment.

For the hop bill I was going to do something scientific such as halve the above figures and add a little bit!

Would anyone like to pull this to pieces for me?

Thanks
Oz

I'll do my best to explain my thoughts and I'm sure there will be others to chime in.

I think there is enough info to convert your extract recipe to an AG recipe, but the information you're giving is a little confusing. The easiest way to convert recipes is to use The Calculator and I highly recommend getting comfortable with it.

You say the original recipe is for "Brew Length 23L". To us on this sight, that means the amount of finished beer after losses to kettle and fermenter trub. I imagine, that if you're getting this recipe from somewhere else, they intended this to be 23L "Batch Size" IOW "volume in the kettle after the boil". With that being said, what would you like for the scaled recipe? Do you want 10L of finished beer or 10L after the boil? Converting your recipe to either should be straightforward and lots of good people around here can help.

If you can clarify this point, we can help you get a good converted recipe.

I should mention, I think you're amounts of grain are far too high. But explaining that can wait until we get the recipe nailed down.

To try to clarify, I think the 23L was the volume after boil.

I'll be trying to get 10L after fermentation so I need a little more 10L after the boil.

The quantity of grain I have specified is based on my first BIAB effort http://www.biabrewer.info/viewtopic.php?f=5&t=517 where I used about 2.6kg and ended up with a OG of 1044. Knowing that I am aiming for 1042OG I have reduced the grain total a little.

Hope that helps!

Thanks

It's amazing how once I fixate on something, the rest of a post becomes irrelevant. By this I mean that I completely misread your OP and my comment on learning to use The Calculator can be neglected (you obviously know how).

When I read:

I failed to see that this was converting the extract to full-volume AG recipe; I thought this was your scaled amounts for a 10L brew. :idiot: :headhit: :sneak:

So now that I'm reading it correctly :idea: the amounts of grains you're giving match exactly to what I'm getting with the The Calculator.

As for the hops, assuming that the AA% for the original recipe and the scaled recipe are the same or close, then you're reasoning should get you really close.

Thanks for that, the hops will be out the same packets as the extract brew, which have since been stored in the freezer. Now all I need to do is drink some beer to free up some bottles.... such a hard life sometimes!

Oz, you learn something new every day. I have never heard the term, "spray malt," before. I assume this obviously means dried extract?

LOL BBH. I never done this :whistle: .

As a penalty I think you should answer the next question asked in the Use this thread to convert recipes to suit your equipment... thread.

Hi PP (may I call you PP?)

Spraymalt is indeed a term used widely here in the UK for dried malt extract. I had wrongly thought it was a universally understood expression.

All the best!

Spraymalt could well be a common term oz. I have never done extract brewing so this is one of many areas where my knowledge is definitely sub-standard.

I'm not sure about calling me PP - it might be a bit familiar :o :lol:. My first name is Patrick and on other forums, I sign off as Pat. If I did this here though, I might get mixed up with the admin Pat here who writes a lot more sensibly than I do :lol:. Maybe I should start writing Patch instead of PP?

:peace:

P.S. I have just received a PM from BBH. He was bit too shy to offer this on-forum but he wants all posters with recipe conversions to stop using the thread I linked in my last post here and PM him directly. He's a good man! :lol: :lol: :lol:

PP, as explained to me by my LHBS some years ago, it is Dried Light Malt Extract that has been treated (I guess spray dried) so that it is finer than standard DLME. It absorbs moisture like you wouldn't believe and I found it to be a real PITA when adding it after (K & K) boiling for hop extraction (I hope you get what I mean) before adding the can, as it tends to clump up. Has anyone got a thesaurus which will enable me to use the correct brewing terms. FWIW I know what I mean.

Quite right, my very first order for an extract brew had 3 x 1kg bags of the stuff. I was so excited when the ingredients were delivered (hops, yeast, speciality grains), like a kid at Christmas. That excitement didn't last long though as when I opened the box up one of the bags of spraymalt had split while in transit. It left one huge sticky mess, everything was stuck to everything else...delayed my brew day as I had to clean everything up and wait for a replacement to be dispatched. Bl00dy stuff!!!

Anyway. back to BIAB. My grains arrived today so I will have go at my best bitter tomorrow, all being well. Will post back after!

Cheers

I thought all DME is dried by spraying it.

I once had an LME open slightly and make a mess all over everything. No replacement and the online shop was very wonky, last time I'll get from there. A shame too as they are the only one with Alderwood Smoked malt for a porter resembling Alaskan's.
