Justin,

Thanks for pointing this out. I'll fix this right away!

 

[Wyrmwood]

This thing is awesome! I am new to brewing and looked at this a couple of months ago and was completely flummoxed! I came back to it today and have already drummed up a few recipes! It's amazing what a little vocabulary can do

**Hats off and glass raised!! **

If I was going to make a small suggestion for the next revision - how about an ingredient list to take to your lhbs (or your olbs). I know print drivers and the like can be a pain, so even a simple text list that you can copy/paste into your favorite text editor/ word processor would be sufficient to print off and run to the store!

Thanks again for all your hard work!

The plaintext version is already there: Tools->Recipe to clipboard. Then, you can hit "paste" in notepad.
We've also got nicely formatted and native printing in the next version thanks to mikfire.

When is this next "update" coming out that will have the a more dedicated extract setup?

 

[Wyrmwood]

Gotcha. The problem is that the other recipe is probably using a lower yield for the steeped grain. In 1.2.2, brewtarget doesn't adjust the yield downwards when steeping, but that is about to change with 1.2.3. For now, if you steep a grain, just cut the yield of that grain in half.

I have been using this table
http://www.howtobrew.com/section2/chapter12-4-1.html
and entering 0 for anything that is -- and (PPG Steep / Max PPG) * Max Yield to get Steep Yield for everything else. Sound about right?

Heya rocketman,

I think if you could add some calculators for strike temps, infusion temps, and stuff in the tools menu it would be awesome.

 

[user 19629]

I would like to see the quarts per pound ratio and the malt bill %'s, when you copy the recipe to the clip board.

Does this still apply with 1.2.3, or is that steep setting doing this "under the hood"?

No need to do this in 1.2.3. Happens automatically.

Not a big deal, but another thing I noticed.
If you have a fermentable that is not mashed, such as a sugar that is going into the kettle. When you copy recipe to clipboard it includes that in the "total grain"
it might be helpful if that could be listed separately, as a "kettle adjunct " or something?

 

[Wyrmwood]

I have been fine tuning several recipes and really digging how easy this tool makes it! I am also going to do a "mini-mash" on Sunday, and Brewtarget will help me gauge expected versus actual efficiency.

I do have one question though, what is the formula you are using for ABV? No matter what formula I use, if I enter the anticipated OG and FG Brewtarget states, my resulting ABV is always lower.

For example, a porter I have entered has an OG of 1.076 and an FG of 1.019. Using
ABV % = ((1.05 x (OG - TG))/TG)/0.79
I get 7.4%, but Brewtarget says ABV is 8.0%. If I use http://www.rooftopbrew.net/abv_calculator.php it's 7.6%, but I don't know what formula that site's using.

In 1.2.2 it is using Dave Miller's approximation
ABV = 130*(og-fg)
from The Complete Handbook of Homebrewing, 1988, Storey Communications.

I think your formula given above pretty much agrees with Miller's.

Do you have a more accurate formula?

I am using 1.2.3
I've been using the one from wikipedia
http://en.wikipedia.org/wiki/Alcohol_by_volume#Beer
ABV = ((1.05 * (Starting SG – Final SG)) / Final SG) / 0.79 * 100

 

[rocketman768]

I am using 1.2.3

Ah yeah, there is a small issue with the current revision's calculation of ABV. Internally, it is first calculating ABW then converting to ABV, but ABW to ABV is not a very accurate conversion. Will fix this before the final release.

This is awesome, thanks for all the time you've put into this! I've been working off of trial Promash for about 3 years, with a bunch of random Excel files to supplement.....this brings it all together. Again, thanks!

I am having a hard time figuring out how to set up a mash..even after reading the manual...I've entered my equipment (5.25 batch, 7.25 preboil (yes, I do boil off 2gal/hr), plastic mash tun, 3 qts deadspace, etc., etc.). I only do batch sparges, with a single infusion to start, and a sparge addition after that (try to hold the runnings to equal volume, or as close as I can). How do I set this up? I've tried manually adding mash steps, using the mash designer, the mash wiz, and what comes out is basically nonsense (add 0 oz at 32 f when I tell it I want to hit a mash temp of 150 for an hour). Is there any additional reading I can do? If not, can you point me in the right direction?

Thanks!

Just to make sure, you are entering the following "150 F" into the field for temperature (that's 1-5-0-space-F) right?

To me, the mash designer is the easiest to use. Start it, select infusion, put "150 F" as the temperature, then drag the infusion volume or temp slider where you want it. If you drag the temp slider, it will change the volume so that you hit 150 F, and if you drag the volume slider, it will change the temp slider. If for some reason this is not working, PM me and we'll get you straightened out.

I'm not sure if this is me or not but,
When copying a recipe to clip board and then pasting, I get: "Boil Time: 0.000 s:" Even though I have a boil time setup in my equipment. I'm not sure where it's grabbing that from.

Anytime I create/add a new recipe, it defaults to 70% eff. Can that be changed to a different default or pulled off the selected equipment page?

 

[gak27]

Rocketman,

A quick question about a feature that I know was mentioned as a possibility before but I truthfully haven't followed its status:

sometime in the past, someone suggested 'up' and 'down' arrows that could be used to move the ingredients up and down, rather than the current 'last added on the bottom' method; whatever happened to this idea (and apologies if this has already been discussed somewhere)...

It's just a bug in 1.2.2.

Not right now. But could be a good feature.

In the upcoming 1.2.3, all these lists are now sortable by column. So for example, you can sort hops by addition time or type or amount etc. Is that good you think?

Sounds good to me...thanks!

I input my exact recipe into BeerSmith and Brewtarget. Beersmith was spot on as far as OG & FG and ABV, etc while Brewtarget was off on OG by 6 points and a few on FG and ABV. Why the inconsistency?

Most likely the default efficiency values for the grains you used and attenuation of your yeast. I think brew target takes the average of the yeasts attenuation range and uses that number to calculate FG. If you mash on the hot side you will have less attenuation, colder side and you will have more.

Could you do me a favor and export the recipe to XML and post it? I have heard about this behavior but haven't had time to make a test case for myself. I would like to figure out what the discrepancy is and, if required, fix it.

Thanks,
Mik

jvcjbl,

There is no way Beersmith is correct on this one. Let me formulate it by hand to demonstrate:

==Grains==
(2/16)*0.72 +(6/16)*0.74+(2/16)*0.70+(10/16)*.74
= 0.9175 lb of glucose (maximum)

==Sugars==
6*0.78 = 4.68 lb of glucose

==70% Efficiency==
0.9175*0.70 + 4.68 = 5.322 lb of glucose
(Efficiency is only applied to grains, not sugars)

==OG==
5.322 lb / 5.25 gal * 46 points/(lb*gal) = 46.6 points, i.e. 1.047.

You can do the same analysis with the Beersmith recipe and you will come up with 1.044 using their given yield % numbers. The only way to get an OG of 1.054 is to have at least 6.17 lb of glucose in the beer, since 6.17 lb / 5.25 gal * 46 points/(lb*gal) = 54 points, which is impossible with the given recipe.

Can anyone else find a problem here?

I have a recipe sheet from the Brewery from the Brew Master. I input everything that was on the sheet and the EXACT quantities and it is EXACTLY what they have as far as OG and FG and ABV. I mean to the T exactly! I used those exact quantities per BeerSmith and hit it spot on. This is the second time I have brewed this beer with the exact same results. Brewtarget was off all the way around.

 

[mikfire]

(snip)
Light Malt Extract Extract 6.000 lb No No 78% 4 L
(snip)
6 lbs Light Malt Extract (4.0 SRM) Sugar 82.8 %

(emphasis mine)

Okay. I have been playing with this a bit because I couldn't get my version of beersmith to come anywhere near your numbers. No matter how I tried, I got an OG of 1.049 which was close enough to brewtarget's to simply be round off errors.

I noticed that I didn't have a "Light Malt Extract" (I am trying very hard to not use LME, because that has a completely different meaning in this context) in the list of ingredients in my version of beersmith, so I assumed you added it yourself. And then I think I spotted the problem.

You have defined the "Light Malt Extract" as a sugar in beersmith, but as an extract in brewtarget. A sugar is considered completely fermentable assuming your target ABV is within the tolerance of the yeast. Extracts are not. If I replaced your 6 lbs of "Light Malt Extract" with a pure sugar, my numbers suddenly agreed with yours.

So is your "Light Malt Extract" a sugar, e.g., table sugar or brown sugar? Or is it a malt extract? Additionally, if it is an extract, is it a liquid or dry extract? The dry usually has a bit more sugar to it.

Yes. I know. This still doesn't explain why your measurements exactly match the expected OG when using the sugar in the calculations. If it is a dry malt extract and not a liquid, the dry malt has just enough more fermentable sugar in it to make up the difference. The exact difference between LME and DME depends on the tables you are looking at, and will vary from batch to batch of each.
