Very nice. Thank you.

Decided against the recipe contest entries, huh?

That thread kinda died...probably because I couldn't provide a really good motivation for recipe submission. But yeah, just didn't collect enough recipes.

How is the Rager IBU formula being calculated? When I enter hop additions for 0.00 seconds I am getting some IBUs. Shouldn't it be 0? I'm trying to accurately adjust some recipes from Brewing Classic Styles and they user rager.

LOVE the Scale recipe in this version! Thanks rocketman!

Thanks!

The Rager calculations are being done according to http://realbeer.com/hops/FAQ.html

The formulas are (from brewtarget's source code):
Code:
utilization = (18.11 + 13.86*tanh((minutes-31.32)/18.17)) / 100.0;
if( wort_grav > 1.050 )
   gravityFactor = (wort_grav - 1.050)/0.2;
else
   gravityFactor = 0;
IBU = (hops_grams*utilization*AArating*1000)/(finalVolume_liters*(1+gravityFactor));
So yeah. If you plug in 0 for the "minutes," you will get 5% utilization. Rager's approximation doesn't actually go to 0 IBUs if you put in hops for 0 minutes.

Ya that makes sense. The IBUs are matching "Brewing Classic Styles" recipes for all the other additions. I guess when they wrote the book they edited the 0 min additions to read as 0 IBUs.

Ain't happening for a variety of reasons, but for Playbook and future blackberry devices it should be no more complicated than Android... finally.

very nice!

I am having an issue with the new brewday mode.
If I generate a new step, the instructions I type in keep disappearing if I move away from the step I just created. The step is still there, just not the instructions.

Alright, I see it. Thanks for the bug report and I'll fix it ASAP.

Can i assume, based on the simple install instructions, that brewtarget could be unzipped to a usb stick and run from there?

i've actually already done this and it seems to be working, just wanted to ask if you thought there might be any foreseeable problems.

Thanks so much for this software!
