   Guys, I just tried using BIABacus with Google's new Add-in for Chrome Office Editing for Docs
   
   and lo and behold BIABacas seems to work perfectly.
   
   My testing wasn't thorough but I tried changing a few things such as;
   
   Desired VIF
   Hop AA%
   Desired Gravity
   Changed Evap Rate
   Desired IBU's
   
   Each time the BIABacus Spreadsheet Recalculated and did what it was supposed to. :thumbs:
   
   This may be a very handy add-in for those living in the Apple or I-Pad worlds (Yet to test it on those platforms,...

   LibreOffice works well on any platform and stays protected as long as users always save the file as an .xls. The only change that occurs is in the colours but that is not much to worry about.

   Hi!
   I'll brew my first beer in two days. I have a few questions about the measurement I will take in order to fill the BIABacus.
   I searched the forum for these answers but I really couldn't find everything I need.
   I know this is a lot but, even if I don't fully understand the meaning and the impact of every measure the BIABacus accepts, I'd like to keep track of all the things in the BIABacus.
   
   I'll start with the measurements for which I couldn't exactly understand the right measuring moment:...

   On your next brew, if you are a pure BIAB'er and do a mash-out , I'm wondering if you could take two gravity readings and record them here for us.
   
   What is a Pure BIAB?
   
   A pure BIAB is when all the water required in a brew is added to the mash. In other words, there is no active sparging involved.
   
   What is A Mash-Out ?
   
   When BIAB'ing, you can either pull the bag at the end of the mash and then bring this 'sweet liquor' to the boil or you can allow the bag to remain in the sweet liquor and...

   One thing I thought of the other day is that I should have asked people to record their base malt/s as this might explain the difference in some of the more extreme results. If you can remember what base malts you used and have time to edit your posts above, that might help us even more paint a picture.

   So let me start by saying as a new member that the BIABacus looks very powerful, great job! I will be using on my next batch. But my question is in regards to how I currently use brewing software for new recipes.
   
   Entering in a known recipe into BIABacus looks very straight forward. However, many times I do not have a recipe and start from scratch. So I start by adding in x amount of grain into the software. The software then shows me what my estimated OG is. I increase said grain until I reach...

   Nice stuff bundy! Let's do some maths...
   
   BIABacus on your kettle estimates 4.93 litres/hour or 1.3 gal/hour.
   
   Your actual is about 3.5 litres/hour or 0.925 gal/hr
   
   The formula you have linked to would give us with a 2.4kW element...
   
   2400/2256.4*60*60/1000=1.06364*60*60/1000=3.83 litres/hour or 1.01 gal/hour.

   Gents, I just want to see if I am using BIABIcus correctly when it comes to priming calculations.

   In my case I have 21.5 litres going into 500ml bottles. I want a CO2 volume of 3.0, BIABIcus tells me I need 43 bottles and 3.6grams per bottle (Using 500ml Bottles) Now I bulk prime so 43 x 3.6 is 155grams (or...

   Guys, Qstn for the gurus. (Probably one only Pat can answer but we will see)
   
   First time I have used a Hopsock today (Must say I ask myself why I haven't before)
   
   Anyway, when using a hopsock does BIABacus expect you to take measurements with the hopsock still in the Kettle? Or do you remove and measure your EOBV?
   
   When removing the hopsock I had maybe 0.5L of Trub in my sock which I guess without a sock would normally be there??
   
   Anyway just clearing up as to what others do

   Thanks Mally, good pickup. I obviously have an old biabicus version and just glanced at the fields to be sure I was talking about the right fields. I'll have to make sure I am using the latest one next time though so as to avoid confusion.

12. BIABacus -Acct for fermentables added near end of boil?

    How do I acct for fermentables, in this case candi syrup, added with 15 min left in the boil in BIABacus?
    
    I brewed this yesterday and as I was plugging in my actuals to BIABacus as I brewed, my Gravity into Boil was 1.029. I had the candi syrup listed as part of the grain bill, but that appears to cause BIABacus to calculate as if it was there for the full 90 minutes, it calculated a 1.040 estimated GIB. This really caused me great confusion until i realized that I didn't add my candi syrup...

    Last post

    Well I checked out the new version and sure enough, there it is, I can now set my candi syrup to be a boil addition.
    
    Great job on 1.3T and especially the inclusion of the ability to separate the fermentables that are added during the boil! :clap: :thumbs: :party:

    So, I got my shiny new 10 tip natural gas burner in the mail and my shiny new 60qt Stainless Concord pot and decided I needed to test the Evaporation rate with just a straight water boil test, no grains.
    
    Here are my numbers for a 60 min boil on my 41.9cm x 41.9cm pot:
    
    --5Gal of water, which measured 5.375 in my pot, slightly less than the 5.41 that Biabacus predicts; probably a neglible difference
    --Volume at beginning of boil was still 5.375
    --Volume measured hot at Flame-out (VFO)was 3.75...

    Last post

    Something is wrong here, 60 quarts vs. 15.26 gallons.
    
    Lol, you noticed that too, those are the actual dimensions, measured 3x, 41.9cm x 41.9cm and the pot is stamped 60Qt and is also sold online as 60qt.
    
    Didn't really think it was worth worrying about, especially since the diameter (most important dimension in my mind) is dead on exactly 41.9cm.

    So I tried the Biabicus for the first time. To create this recipe I have used the ingredients from a lagunitas clone.

For example I had about 8 pounds of grains and Un fermentables. So I just kept this same weight measurement , I did the same with the hops. Then I simply divided the grain bill weight by the three new grains proportionally In my mind this...

My problem was that i didnt understand that the the original grain bill design was the LI recipe. Kinda of a DuH moment for me :scratch: Anyhow I am feeling more confident now with the Biabicus. I think my next brew will be an original design instead of a clone.Thanks to all for helping me again.PP,MS and Yeasty. I will update you guys on this LLSS clone recipe when its complete.

    I just took a gravity reading from my latest beer to see if it was finished, as I generally do. I filled the test jar up and put in the hydrometer and took the reading 1.014, not finished, I need to give it some more time. Why do I need to take another one, can I not leave the beer in the test jar with the hydrometer in it, at the same temp as my fermenter and watch it until it is finished?

I kind of stopped taking final gravity readings too but some of my beers lately (the bottled ones) have seemed a bit overcarbonated and I wanted to squeeze all the gravity points I could out of this one. Also I've been doing cask ales and want to try racking to the pin a couple of points early instead of priming. As usual you have the answers!

Looking at a few minutes I realized that if you take the specific gravity say 1.048 and divide the 48 by four you get plato 12 which is correct. Likewise 10 Plato * 4 = 1.040. I did not know that' did all y'all? I'm sure this is not new but it's nice to be able to do things quickly in your noggin. :headhit: Seems easier than the complicated formula below and works in the normal...

    I haven't used plato, but this would be handy printed off and stuck to the brew fridge for a quick reference.

    I have a question that has been bugging me for some time now, and i wondered if anybody else has encountered something similar?
    for my last few brews i have noticed a trend when carrying out the procedure (below). Where the post boil but pre-chill gravity appears higher
    than the chilled gravity.
    
    1) After mash but pre-mashout; take a 5ml sample for the refractometer ALLOW TO COOL. Take reading.
    2) After mashout but pre-boil; take a 5ml sample for the refractometer ALLOW TO COOL. Take reading....

    Yes, with such small samples, it doesn't take much to through it off.. That's the best my mind can do w/o being there :)

    So I am perplexed as to why my efficiency is lacking and I am hoping someone here can give me some advice as to what I am doing wrong. The following is the basic recipe used.
    
    I crushed the grains from 030, and 028 and double crushed at 028(030 was the first batch and 028 was the second batch). Did a 90 minute mash stirred at the doe-in until there was no doe balls. Preheated oven to 155 f, but the pot inside the oven and stirred again at 45, and 90 minute mark. After that I did a rest at...

    Looks like the guys have got a lot of your questions sorted johns. Good on 'em!
    
    I've tidied up your BIABAcus file and for the reasons GR explained above, I have posted it in this post of the thread he linked. You'll also find a lot more info on the BeerSmith side of things in a link I have included in the other post.
    
    Have fun!
