   Just a little question about the calculator: the grain bill parameter is intended for the base malt only or it includes also speciality grains?

   Ok, that's enough for me, then! ;)

   At new version of BREWMATE V 1.06 Rob added BIAB support . I've done some tests with the Calculator spreadsheet and it is very accurate . Test yourselves too and if you find any glitch we can contact Rob to take care of it .
   Very good work in my opinion .

   nik and shibolet,
   
   Your offers above to translate the new calculator are greatly appreciated. That would be brilliant :salute:. It might be a lot of work though so feel free to back out - lol.
   
   thughes,
   
   What we are doing is initially concentrating on getting the sheet to work under Excel 97. After that is completed, we can get it out there and then we are hoping a Libra / Open Office expert will put their hand up to make it work under Libra / Open Office which hopefully won't be too difficult....

   Is the new calculator usable yet,or should we be still using the March 2011 version?
   I have absolutely no need for an expensive spreadsheet like Excel,and I hope that,if/when it is usable,it will it be compatable with OpenOffice.

6. BeerSmith2 - FWH

   I'm interested in knowing how BeerSmith2 calculates FWH's. In another piece of software you can select the amount of time. What, if any, is the standard time and temperatures of FWH? Is it based off of a fixed temperature to when it reaches boiling temp?
   
   I would think some of you do alot of FWH and combine it with late hop additions (such as 10 min. hops). What is the percentages (weights) of hops used in FWH to Late Adddition Hops? Thanks...

   I haven't looked at this side of things as yet MS.
   
   It's a good idea though to join the BeerSmith forum and ask these types of questions here as Brad reads the forum every day and will certainly answer things like this. Try and word your questions as clearly as possible and try and play with the program first yourself to see what effects changing certain things does.
   
   Good question MS!

8. IBU Scaling in a concentrated wort?

   21 Replies 21546 Views

   First post by stux, 14 years ago

   So,
   
   If we wanted 20L of wort at OG (ie not concentrated) and we hopped that to 20IBU, that would be one thing,
   
   now say we had a concentrated wort prepared to 15L, and we wanted to post-boil dilute this back to 20L, would that mean that actually you need to aim for 33% more IBUs during the boil, so that post boil you get 20IBU?
   
   15L at 26.66 IBU + 5L of water = 20L at 20IBU?

   New brewers (and plenty of more experienced ones), often think that a single reading of a single sample at a single stage of a single brew using a single instrument will give them an accurate reading. Written like this, this expectation seems a bit silly but it took me a long time to learn just how much a single reading should be ignored.
   
   Some new brewers will post after their first brew that their efficiency was terrible. And it well might have been for any one of the reasons listed here ....

10. cheap Chinese refractometer

    hi guys,
    i bought this cheap chinese refractometer on ebay.
    it seems to work fine except for one thing: it has a dig. plato scale and an SG scale and they don't seem to agree with each other
    that is, if the plato scale says 13.1 the calculators tell me that that's 1.053 SG, but the refractometer SG scale says 1.051.
    
    i remember reading/hearing somewhere that i should be following the plato scale and disregarding the SG scale. can anyone corroborate this?

    As I only brew beers with an OG of less than 1.060 I bought one of these 0 - 18% Brix refractometers
    
    If brewing stronger beers then go the 0 - 32% Brix version.
    
    I use it for both before and after fermentation SG's using a formula to correct for alcohol. Get good agreement between refractometer and hydrometer.
    
    Broke my hydrometer recently (had it 40 years) won't be replacing it.

    LOL, I can see exactly where I stopped reading that post...
    
    Utilization can be reduced to a smooth function, as opposed to the tables, which produce many discontinuous lines. The Rager table is presented in the following utilization equation:
    
    %UTILIZATION = 18.11 + 13.86 * hyptan
    Whilst I can have a laugh, the above shows just how much study and hard work goes into making some things simple.

    Here is a batch calculator I made when I first joined BIAB. The goal was to make a spreadsheet that I could use to design different beers. The first page can be used to calculate SG after boil and color or the wort. I also included a dilution schedule, because I am doing maxiBIAB with a 19L pot. After I finish mashing I measure the volume of my wort and plug it into the top left corner. This cell is used by many other cells in sheet.

    Brad is currently trying to get the new version of beersmith into beta, and responded to someone's suggestion of support for BIAB.
    
    How do you think this should be best implemented? I was thinking of a new option in the mash profile that would allow the sparge and mash water to be combined (i.e. a very high volume mash). Is this how you do it or do you usually mash with less water and add water during the boil?

    There are a few methods.

    I think one of the most important considerations should be whether the BIAB is full- volume or not (i.e. sparged). So, make what PP says about mash & sparge figures added together to be optional, not mandatory. It is possible though to fool/ bludgeon at least some existing software into dealing with a sparged BIAB, probably easier than full- volume.
    Having said that, I'm not really a big fan of software for brewing in general, but I generally do only a handful of different styles using recipes...

    Hi all
    so here's my story:
    I've been BIABing for a few months now. I use an electric iron pot (not really an urn . i think it was once used to do laundry). the volume is aprx. 47 liters.
    the pot has a hidden heating element that runs through a cylinder at the bottom of the pot. i think it probably takes up about 1-1.5 lites of space.
    so far i have been using the original BIAB_Equipment_Set_Up_Volumes.xls that only has one worksheet. also, i have been using a tape-measure to estimate the volume...

    Crap, keeping notes, thats what I forgot to do. :? I wrote a note to remind myself.....but forgot where I put it. :lol:
    What you say is funny wiz but it gets even worse!!! I actually often do take good notes while I am brewing but they always get lost afterwards.
    
    You work on your auto-syphon and I'll work on a note-keeping method for BIAB!
    
    Apologies again shibo :).
