The colors at that point are to indicate if you +/- 10% of what the recipe was calculated for. I reused the code from the other displays, and they have that as the standard hover message. I will see if I can find an easy way to fix it.

ok, that makes sense. Started crushing my own grains and saw efficiency improvements that would cause that.

Thanks!

Question to the devs:

I have a custom 3 keggle set up for 10gallons. I used the specific heat and mass of stainless steel in the configuration when I set it up. I said ambient temp is around 60 for the steel (which it is, on my thermometers). I have ~20 pounds of grain for an average batch, at 68 degrees.

I put in that I want a mash of 152 degrees (example) and it says I should have a strike water of 165 or so. When I execute, the actual grain + water temp is ~148.

What settings / variables should I change to actually get 152 (4 degrees higher) for the mash temp?

A good rule of thump is 15 degrees above the mash temp. So shoot for 167 for strike water, maybe a hair higher with that much grain.

Hm, but I want it to use the facts and figures to give me the actual value, based on specific heats of multiple substances. There is possibly a small heat-loss to the frame of the sculpture, but I would be surprised that it was 4 degrees.

Rather than rule of thumbing, I am trying to get brew-target to mathematically calculate the temperatures, especially important with variable recipe sizes : )

I have the same issue with a similar setup. Increase the mass of your setup to account for it. Are you heating in the HLT and transferring to the MLT? You need to account for the mass of the transfer hoses/fittings/valves/pumps/etc depending on your setup. Also, at least for me, temp stratification is bad enough in my HLT to throw the whole works off by several degrees if I just heat and go. HTH

Hm : / I am using a setup kind of like this;

Code:
|--|
|--|
|--|    
        |--|     |--|
        |--|     |--|
        |--|     |--|
HLT      MLT      BK
The hose from hlt->mlt is about 7" long made of silicone. Water has a massive specific heat, I am not sure that is the problem, considering the distance traveled is 7".

I will try increasing the mass of the system components. I thought 29.7 pounds was sufficient per keg. What # are you using for weight?

As an aside: I am using a recirculating mash system so I can get up to the proper temps, but I'd like to be at the proper temps to start : )

When will Brewtarget be available for iPad? If ever?

Using BrewTarget 2.0.0 for Mac OS X. I set the equipment to '5 gal extract - full boil' and the batch size is set to 5 gal. However, the calculated batch size is 5.804 gallons. If I toggle over to '5 gal extract - partial boil' it says the same thing. How can I reset this option without having to reenter the recipe?

Can you explain this to me it's a little confusing with adding in Corn sugar. I just made an All Grain IPA, and added in 1lb of Corn Sugar as well. No matter where I put it, it put the Pre Boil Gravity at 1.060, where mine was at 1.052 since the Sugar went in with 5 minutes left in the boil, not at the start of the boil, which this calculated it at. While the final gravity was fine, it project it to be 1.072, and I ended up at 1.070, so the brewhouse eff was a little over 80% which is good.

Is there a way to adjust adding corn sugar in, like you do with hops, and tell it just 5 minutes in the boil, and have it do the gravity correct? I may have missed something, just couldn't figure out how to do this, and then generate instructions for it properly. Everything elses worked fine.
