beercalc is an open source beer recipe calculation and planning tool. It allows you to build a recipe and estimate certain properties of the resultant beer. beercalc is also a set of functions that can be copied and used in other applications.

- written in C (server) and Javascript (web client).
- open source.
- no dependency on webkit.
- full database of malts, hops, yeasts, and styles (styles derived from BJCP 2008/2015 data).
- "auto-style" - automatically suggest best fitting styles by recipe.
- unique polynomial-curve-based SRM-to-RGB estimation.

beercalc is written in C for the server side code and beer recipe calculation code, and javascript for the client side.
It should be noted that the whole idea of this implementation is a little bit silly. It was written for 4 reasons:
1. I was not happy with any available desktop recipe calculators, all either have an insane list of dependencies, are not opensource, or are not sufficient in some other aspect.
2. I wanted to develop another, more interactive, website to run off the unweave webserver.
3. I want to end my reliance on others (in the software realm) step by step.
4. I eventually want to extend this application to interface with custom brewing hardware to improve my brews.
Honestly, none of these reasons hold any value to anyone other than myself, but this software may grow into something that other people might find useful. One of the unique features beercalc offers is the ability to define a recipe, and than based on the defined recipe, find beer styles that best match the recipe. This allows a brewer to reverse the process of developing a recipe, starting with ingredients and stepping backwards into a style, and then fine tuning based on the calculated style. A process like this might encourage more experimental brews and make the recipe building process more exciting.
This implementation is in C, and calculations are done on the server-side. Although C does floating-point calculation as efficiently as javascript (better actually), this implementation could be improved, and hopefully will be. Future improvements will include the option to do all calculations using fixed-point numbers, a client-side command line interface, and a full distribution including software for recipe building and mash and brew monitoring and automation.
