Brewtarget 2.0 Update

[neomantra]

Is there a list of new features/fixes that occurred since the last release? I looked around the Brewtarget web site and couldn't find one. Thanks!

This is what I see.

New in this release

Brewtarget v2.0 has been long in the making, mostly because we have done a massive reworking of the internals.
SQLite DB

We have replaced the old XML files with a brand new SQLite database. We have spent a long time making this as transparent as possible. If we have done our jobs well, the only thing most users should notice is brewtarget seems to load faster and is a bit faster in other places.

We will be using this change to implement inventory, multi-level undo, automatic versioning of recipes, etc. We also hope to allow you to decide which database engine you want to use -- SQLite and mysql at least, postgresql likely.

Units and Scales

This has been a very requested feature that has taken us a long time to implement correctly. You can now override the default unit (e.g., US Customary) per field, and you can control the scale (so your hops are always displayed in grams, no matter how many kilos you are adding).

Tree Views

The trees continue to evolve. They are now split into their own separate tabs and can be sorted on the fields displayed. The next release will let you select which fields are displayed and hopefully allow you to define folders.

Default Equipment

You can select one piece of equipment as the default and any new recipe will have that automatically defined as the equipment. You can do this by opening the equipment profile and selecting the "Set as default" option in the upper left.

Hop Utilization

You can configure your hop utilization from the equipment screen. This may cause your recipes to show 0 IBU. If you are seeing this, set your hop utilization to 100 on your equipment.

I can't seem to change the boiling point of water to a lower temperature.

This is part of the mess I made of the equipment editor. It will be fixed soon.

I wouldn't call anything about this program a "mess".
I say good job, no matter what.

I definitely enjoy this software, do you guys have an idea when a bugfix release will come out for 2.0 to fix the saving of equipment?

Most of the fixes have been commited and rolled into HEAD. I'm not sure what the exact schedule is for releasing the bugfixes, but it should be soon.

Great thanks for the quick response too

Just getting started, and got Brewtarget. In the hops window, additions display as
0.0 IBU, and so main window shows 0.0 IBU.
I also had trouble w/ 64 bit mac dl. 32 works fine.

What sort of trouble? I'm learning how to package for Mac as I go, so the feedback would be useful. It worked on my wife's Macbook Pro, but I know how much that's worth most of the time.

Go into your equipment profile and set the hop utilization to 100. You may need to reset the equipment profile on your recipe.

If that doesn't fix the problem, either respond here or enter a bug on https://bugs.launchpad.net/brewtarget

I’m doing 60 minute partial boils, using extract, with a late addition of half of the extract (last 15 minutes or at flameout).

Brewtarget sets Hop Utilization at 100 by default. Doing a 60 minute boil, shouldn’t it be less? Something like 91 springs to mind from previous reading, but I can’t cite a source offhand.

Also, Setting hops Use to Aroma or Boil if adding the hops at say the last 5 minutes affects IBU. Setting it to Boil raises the IBU. What’s the proper Use setting for hops if added at say 15, 5 and 1 minute before flameout.

Finally, the late addition of half the extract affects IBU, but not the color. Shouldn’t the SMR be lower with the late addition?

After downloading BT 2.0 for Mac, the 64 bit version, the dmg loads fine, and the app gets copied to my HD. But when I try to launch, I get the error "application has unexpectedly quit". There is a retry option, which never works. No such trouble with the 32 bit version. Hope this helps,

I can only address the middle question easily. The proper use setting is boil. The use field is derived from the beerXML standard. According to that standard, an aroma hop does not add to the IBU totals. In reality, any hop addition when the wort is > 160F will result in some amount of alpha acid will be isomerized and, hence, increase the IBU.

I will have to research the answers to the first and third question.

I just wanted to pass on that I am pretty happy with the changes you've made. This is a huge improvement in usability (drag n drop etc) and does everything I need at this point.

Question, do you use data Sean Terrell put together for refractometer calcs? I know he did a lot of work on improving existing calcs in the last 1 to 2 years and came up with some pretty accurate formulas.

I am using the brewtarget_2.0.0-1_amd64.deb on linux mint 14 and I haven't found any problems yet - installed well.

That was some fun research. I have learned an awful lot about hop utilizations and late additions.

The hop utilization percentage on the equipment profile is basically to fudge the results. All of the formulae used to calculate IBUs are basically guesses. They are good guesses, based on a lot of data and some impressive math, but still guesses. The only real way to know what IBU a beer is is to send it to a lab for analysis. The hop utilization percent is used if you have had several of your beers profiled by such a lab, and notice that the measured IBU is always 105% of the Tinseth calculated IBU. Most homebrewers should just leave that as 100% and learn what 50 IBUs (Tinseth) tastes like and go from there.

The SRM should be adjusted for a late addition. At present, there doesn't seem to be any formula I could find that would describe what the difference is. It should also be noted that any such formula would have to take many other variables into account (pH, intensity of the boil, etc.). Braukaiser has a nice (although short) write up http://braukaiser.com/wiki/index.php?title=How_pH_affects_brewing#Maillard_reactions
Until the research is done and the formulaes are generated, we are stuck doing our best to estimate.

Thanks for the replies mikfire. The braukaiser.com article is really interesting. As simple as making beer is at the most basic level, it still amazes me the big variations that can result from subtle differences in the brew/fermentation process.

And thanks to everyone working on Brewtarget, it's great piece of software.

Just DL'd it and started to play with it. It won't save my equipment specs for some reason. Also, it stopped working and crashed right as I was typing in the Notes section.

v2.0.0 has known problems with both. We will be releasing v2.0.1 very soon to address these issues.

Will 2.0.1, install in the same directory, so that we don't have to re-import everything?

Yes. There are no changes being made to the database, so it should just pick up the one you have already converted.

You shouldn't have had to import anything manually anyway. I am rather puzzled by that, because I spent the better part of 3-6 months getting that all to work correctly. I suspect I needed to do better, cross-platform testing (sorry, I'm a linux geek) and I am working on getting a win7 environment built.

Just curious if this has been brought up? I just added some Agave and Sugar to my recipe, selected add after boil(Late Addition). When I generate instructions, those were never added.

That's a new one. I will open the bug report.

First of all, thanks a lot for this software. I've been using it for all of my recipes for a while now and it does a great job. I'm a bit curious as to what you mean by this though:

I recently upgraded to 2.0 and had a go at importing all the old stuff. I have about 30 recipes, a few equipment profiles, and a bunch of custom added fermentables and hops in the ingredients section (I live in New Zealand so the available hops/malts is fairly different to what I assume might be common in the US in particular). I tried to export the entire database in 1.2.4 and import this into 2.0 but the export gave three XML files while the import expected a single sqllite file, or something like that as far as I can remember.

Importing recipes was fine, and while the equipment profiles seemed to transfer locally with the recipe, they weren't available from the equipment tab. I couldn't find any way to import my custom malts/hops, so I chose to stay with 1.2.4 for now.

Am I missing something here? Is there an easy way to transfer this stuff when upgrading? (win7 64 here)

Thanks again for your work, and I can't wait for the inventory management stuff to get in there!

It was supposed to have just worked. I will work on it this weekend and see if I can figure out why it isn't just working, but it will take me some time. Setting up a windows build environment is tricky, and I am not very good at windows.

Thanks a lot. Is this assuming the new version was installed in the same directory as the old one? That's something I didn't try.

That is a really good question. On the linux side, all of the data lives in the same place regardless of where you install the binaries. If the data lives in the installation directory on Windows, that would explain a few things very nicely. If this is working the way I suspect it may be, I will have an explanation and an easy workaround.

I have my windows env built and was able to successfully build brewtarget last night, so I should be able to figure this out this weekend.

playing with brewtarget for the first time. when i select corriander and ginger it adds vanilla and grains of paradise...

Is there a way to download an older version that is stable and will save my stuff?
