Add a kettle souring step

[padraic7a]

Would this be possible?

One typical way this is done is to mash, boil for 10 - 15 mins, add lacto for 48-72 hours and then to do a hop boil.

See http://sourbeerblog.com/lactobacillus-2-0-advanced-techniques-for-fast-souring-beer/ for details.

Is it better for issues like this to go here or in launchpad?

Before posting an issue would it make sense to check beer.xml?

It's doable if the team wants to.

beerXML standard is pretty out of date, is a dead project, and does not support souring. Since it's dead, that's unlikely to change anytime soon. We really need a new beerxml / BeerJSON standard.

Worth noting that BeerJSON recipe schema supports kettle souring, sour mashing, and other forms of wort souring as a mash step option (like infusion, decoction, etc) with additional properties of initial pH, and final pH.

Current issues restricting this

1. Souring is not an option for a mash step. Should behave same as a temperature step.
2. It's quite annoying to create a step that is that long. Entering 48 hours it was automatically changed to 48 minutes. Had to enter 2880 minutes, then it displayed 2 days. To change into hours scale I had to right click the time column and change it to hours. Unfortunately this also affected all other mash steps.

There should be a way to change the unit scale of a single mash step.

The remaining issues are mainly with regards to beerXML, which basically ignores all souring and funky brewing processes. You can't sour mash, or sour wort, or add any cultures (lacto, yeast etc) to anything except to the recipe or "to secondary" whatever that means. So no adding lacto to a mash step, or adding lacto after yeast, or adding yeast before lacto, etc etc. Also no souring wort, then boiling afterwards. This has been addressed in beerJSON, and i would love to get it into brewtarget at some point, but I think there's more pressing issues and don't want to delay the pending release with this.

Hi Mark,

thanks for the info. I must check out beerjson. This is off topic now but I wonder if you could tell me where the best place to keep track of Brewtartget development is? From the activity here on github I wouldn't have guessed that there is an upcoming release.

Not sure when it'll be, i suppose pending was the wrong word. Next release. I think if we can get the current pull requests approved, and close the bugs and few issues in the to-do column of the project board then I think we would be ready for testing of a new release but I can't speak for the main dev group.
