Hiebster Joshua has given you the best bit of advice you are likely to get at this stage of the process. Download and look at BIABacus. Fill in sections B, C and then watch the result for TWN in section K as you change the OG in section C and the VIF in section B. Play around with those two numbers ...

I use these. They are expensive for a bit of plastic but are a set and forget option. :sleep: and I've forgotten when I last cleaned them :blush: Short lines are, I find, easier to handle.

Lars It's in the low 40deg C range here at the moment. Makes getting to strike temp fairly easy. I would try a few more brews to see if your temerature drop was an aberration or not. Sometimes the brewing gods do strange things. As a side note in section D enter either The Volume Of Ambient Wort (VA...

BDP As Mally says, If you add sugar you give the yeast a bit more to eat and hence a higher ABV. You can carbonate by either adding sugar at packaging time (Priming) or by adding CO2 manually (forced carbonation). I prefer priming, but only because it's slightly easier and I have the time.

leighaus Welcome onto the slippery slope of BIAB. You've done very well. You are right when you say a sky hook would help. Using it gives you two free hands and I just suspend the bag over my kettle whilst I bring it to boil. Any free wort will drain by itself and there is no need to squeeze the las...

onkeltuka Congratulations. I can't fault your attempt at BIABacus. :thumbs: Your grain bill is changing for a couple of reasons. Firstly as Mally said, The left hand side represents a ratio more than the actual grain bill. Your percentages added to 90% rather than 100%. BIABacus has allowed for that...

onkeltuka You have found one of the basic flaws found in most recipes out there. The terminology is unclear. as you say, what does 30 litres mean? The original brewer most probably knew but didn,t tell anyone. The same with "efficiency". Do a search on this forum and you will find pages of discussio...

HbgBill I'll meet you halfway and settle on section C for the OG comment. You are correct in saying enter the original recipe on the left hand side and then use the VIF to give you the right hand side that you want. As to your temperature losses, BIAB normally uses one vessel so that when you mash i...

HbgBill Welcome aboard :salute: To answer your second question first (because it's easier) BIABacus is designed specifically for the "Brew In A Bag" method. Your original recipe was put together for an unknown system with an unknown "efficiency". BIABacus uses the original OG from your recipe and th...

Rad :blush: One small change you need to add. You have copied the hop bill into section D but you have omitted to give either, the VAW figure for the original recipe (and good luck finding that) or the IBU's that you want to scale the recipe to. The original states 25.8 IBU's but doesn't state what ...

alanem Welcome to the BIABacus world. To answer the most pressing question first, BIABacus is telling you exactly what you have asked of it. The reason it looks "loopy" is that in section x you have adjusted your kettle efficiency by one percent and set the efficiency to 3 percent. That would make y...

rbcon2 Welcome to the slippery slope of brewing your own beer. :salute: Contrarian has given you good advice on the equipment you need. Don't start with a lot of gear you don't need. You can spend any amount of money you want on gadgets after that, but it unlikely your beer will be much better. If y...

BDP, PP I am with you in the maths (and I love the method of forcing VAW. I have always modified KFL but not VIF to get want I wanted). I believed that extract potential (which you've not yet discussed) was the maximum theoretical amount of sugar that you could get from a source. I can now see that ...
