1. BIABacus Rudder Corrections for Mini-BIAB

   I am a small batch brewer (1 gallon/3.8L). I recently conducted my third mini-BIAB attempting to clone Bass Ale. I have found the BIABacus to be extremely helpful, but want to ensure that I am getting the most out of it. I was hoping that someone could take a look at my numbers and see if I am on track, or if there is something that i could do to improve my brewing process. My biggest concern after my most recent brew was the amount of trub in my fermenter after transfer. I am used to trub, but...

   I keep refining my APA recipe, and I’ll be changing two things on my next batch: making a late addition of hops for both flavor and some modified bitterness, and dropping the Crystal Malt from 60 to 15 to lessen the caramel flavor I've been getting. The caramel flavor has been too noticeable, overpowering the other beer flavors I’m looking for, thus the reason for reducing the Crystal Malt.
   By changing from Crystal 60L to 15L, while keeping the % of Crystal malt the same in relation to the...

   MS and Scott, thank you for your replies. MS, It took me some thought but it finally hit me what you were saying about percentages. Yes, I'll start playing with that.
   Scott, that article is pretty interesting. I hadn't considered dropping the Crystal altogether and bringing in another malt, but I agree with Tony Lawrence about sweetness masking other flavors. I may drop Crystal altogether and substitute another malt - looks like I've got some research to do, and pretty darned quick.

   It's been a while since I had time to think about my next batch, but things are settling down and I'm tweaking my current recipe.
   In reviewing the attached recipe I see that in section A and B under SRM the sum comes up with a Value! notice. Typically on Excel spreadsheets I see this when I've messed up a formula. If I play around with numbers I don't seem to be able to get it to go away. What am I doing wrong?

   Morebeer is having an Xmas sale with 12% off most things on their site. This includes their  Russian River's Pliny the Elder kit , which is $51 (with yeast), or $44.88 after the 12% discount. I reckon it would cost at least $62 if I bought the ingredients from my local homebrew shop. So I'm kinda into the idea of brewing this great IPA at a somewhat reduced price. Question: How hard is it to set up the recipe in the BIABacus? Below...

    Starting Gravity of 1.057 and FG of 1.014 are  within an APA style.  APA's are supposed to feature a slight sweetness but not as much caramel of British pale ales.   
    The 13% Crystal malts will accounted for un-fermentable sugars for a Pale Ale, maybe more like a British Pale Ale.   Then the high mash temp of 156 for sure would ensure un-fermerntable sugars.

    What I think PP was saying is that if your water reaches 70 and you turn the heat off the residual heat of your kettle will actually raise the water temperature more. Did you fill in section E on the biabacus with your grain temperature? That will tell you what strike temperature to use. My kettle is pretty thick so I stop heating and couple degrees lower to compensate for the kettle heat.

Perhaps because cherries have a 'skin' they don't decompose as much. The nice thing about the bucket and bag approach is that you can use a sanitized...

    The intended use is to add gravity without fermentability. How to Brew lists it as contributing about 40 ppg, and it is marginally fermentable.
    
    Is there a way to deal with this in BIABacus so that it:

    * adjusts OG, FG, etc. according to the gravity contribution and lower fermentability
    * does not...

    So I put 500g of malto into a sauce pot and boiled it up and cooled it in the fridge, added it to the keg. Now of course it is all subjective really but I felt it really repaired the problem of mouthfeel and when I served it at a party no one seemed to think it was thin and drank the whole keg up

    I'm a mini BIAB brewer with a 15L pot and am getting 9.5-10L into the fermenter.
    
    Basically I'm mashing in with 10L strike water, adding around 5 L or thereabouts before the boil to give me a boil volume of about 14L and after Evap (1.3L / hr) and trub losses and regularly ending up with 10L brews.
    
    This is all based on BIABacus and the withholding water section towards the end. Reaching OG of 1.05 with 2kg grain bills no problem.
