Brew Day Tools

Brew Day

This repositiory is a set of utilities for the homebrewer. It should help in constructing and analyzing recipes. There are also command line utilities for brew day.

The hope is to help improve your planning and execution when making beer.

Recipe Examples

To see examples of this library in action check out the examples/ directory or read the Example README.md for more information.

Tools

To be helpful a few tools have been included. Run them thusly:

$ PYTHONPATH=$PYTHONPATH: python bin/abv -h
$ PYTHONPATH=$PYTHONPATH: python bin/sugar -h
$ PYTHONPATH=$PYTHONPATH: python bin/temp -h
$ PYTHONPATH=$PYTHONPATH: python bin/yeast -h

Charts

In an attempt to understand the data as it is presented in various brewing books and websites the charts/ directory attempts to reproduce them using the tools of this library. Credit is given as best as possible to the original author. Corrections are made where possible to make the charts as accurate as possible.

A note on Graphs

Importantly these charts are generally lists of numbers and NOT graphs. To limit the required dependencies of this library any graphs are kept in the BrewSci repo.

Data

The data/ directory holds data used by parsers in the repo to build recipes. The data was gathered using Scrapy to gather info from different brewing websites. The scraping code exists there along with the following data dirs:

• cereals/

• hops/

• water/

• yeast/

All the data is formatted in *.json files. The files are guaranteed to work with the parsers in this library.

Units

The standard for this repository at the moment is to use Imperial Units. This is because most of the equations used as reference use Imperial Units. As tests are updated units may change to SI Units (metric). Not all methods work with SI Units yet.

Percentages

A fair number of methods require input values as a percentage. To avoid confusion all percentages are expected to be in decimal form between the number 0.0 and 1.0.

There still remain some methods that return percentages not in decimal form, notably the ABV utilities.
