Trying Brewtarget Software, have some questions

Sat Aug 06, 2011 7:59 am

Hi all,

1st post to forums, I've been home brewing for about 4 years and have recently moved to all-grain brewing and have found the Jamil Show and other podcasts on the BN and have been listening to those a great deal lately. Beersmith gets mentioned often on the shows, but I've also found Brewtarget, which is free and works on my OS (Linux). I made a batch of witbier yesterday using Jamil's recipe out of his book, and just now put Jami'ls American Rye Ale recipe into the software, as that's my next planned batch to make. Looking at these recipes in the software, it looks like several paramaters are 'out of style' even though I'm entering the exact ingredients in the recipe. I understand that there are numerous parameters regarding equiment, mash steps, etc, that I may be missing, so I figured I'd ask.

For my witbier, my OG, FG, and Color are too high, and the taste of the beer is described as 'extra malty.' When I made this recipe yesterday, my mash temps were off (protien rest was 123.2 degrees-- target was 122, and conversion rest was 149.5 degrees-- target was 154, and sparge temp was 156.7 degrees-- target was 165), and my final wort was nearly 1 gallon less than my target. I did do a 90 minute boil and had only programmed 60 minutes into the recipe (fixed that after the fact), so that should be about .375 gallons lost in that extra boil, but still that means I'm almost 2/3 gallon short. I like this software so far, but hope I can 'dial it in' a little to be able to get closer on my mash temps and final wort amounts.

When I put in the American Rye ale recipe, it too shows several parameters out of style (OG, FG, and ABV) and IBU's are at 16 with a range of 15-30, so it's almost out of style also. The recipe is described as 'cloying'.

Does anyone have any insight on what I can do with this software to get my temps closer to 'real life', get my final wort amounts closer to ideal, and should I worry about the software's 'out of style' warnings and less than ideal descriptions ('extra malty' for a witbier and 'cloying' for an American Rye Ale)? I'd like to brew these recipes true to Jamil's instructions at least the 1st time before I go and try to modify them, and am really surprised that they are coming up 'out of style' considering how good Jamil is at this stuff! I'd suspect the software to be in error long before I'd suspect his recipes! Does anyone else use Brewtarget software, and are there any tips to get a better grip on using it properly? Thanks very much for any help.

Wendallsan,
I just downloaded BrewTarget yesterday and started using it on my mac. Previously I used Beertools for about 4 years and brewed all grain the whole time. I noticed the mash strike temps seemed odd to met. I brew nearly the same ipa all the time and have just about memorized my recipe. When I input it into brewtarget I thought the strike temps were a little low. My guess, is that the equipment section of Brewtarget needs to be adjusted to account for heat loss, but that is just a guess.

As a temporary fix for me, in the mash section (edit mash) I changed the tun temp to equal my target mash rest (152) and then the math seemed to work. In reality, this is actually accurate for me. I mash in a cooler and I always put my strike water in the cooler first at about 10 degrees higher than most software/spreadsheets calculate the infusion temp. As the cooler heats up, pulling heat from the strike water, the strike water temp will gradually fall as long as I leave the cooler lid off. I use digital thermometer and monitor the water temp until it falls to the software calculated "strike temp." So, long story short, my cooler is at strike temp when I add my grain.

As for the out of style parameters, don't worry about that shit, use Jamil's recipes. I only caution this, make sure the size of the batch you inputting in your software is equal to the size in Jamil's recipe, that may fix some issues.

Keep brewin soldier.

Your equipment plays a big part in getting you numbers right, boil off is big thing you can't just guess at. How vigorous is your boil? How much surface area does the top of the liquid have? Those types of things effect how much water you will drive off, so make sure you can set that info up in your software.

I just gotta say here that since I'm not using any brewing software yet, I'm really pleased with how well I'm doing hitting mash temps, boil volumes and og levels, ect. I think the experience on your own equiptment really makes all the difference with these consistencies. I guess like the way a chief cooks, becomes intuitive. Even for recipie formulation seems like the learning by trial and applying what I've read is serving me really well. I have been using some online calcs, water profile, IBU, pitching rate and such. I always made the holiday cheese balls :shock: that I took to work by hand, never using a food processor. My boss always said the analogue always tasted better than the digital version. Anyways, just sayin, I may end up using brewing sotware someday soon.

I guess what I'm tryin to say is, if I had to choose between the information that a brewing software program would give and what I get from the BN Army, there would be no question. :jnj

Hi all, thanks for the input.

I am using a new brew kettle which is very large and has a large surface area. It's a 12 gallon aluminum pot that I'm guessing is 2.5 - 3 feet in diameter. The boil is rolling but not 'maxxed out' and flying out of the kettle, just enough to keep the surface of the wort actively moving around during the boil. I think that my problem is definately my setup in the software, as I can change my setup from the preset I made based on my gear to any other 'preset' setups and the numbers look much closer to style. I'll spend some time looking through these settings and see if I can find what I'm doing wrong. Thanks again everyone for the help, I'll post back again with my updated setup once I know what I'm doing and try to get some feedback again if I'm still off.
