# 🍺 Top-down Brew: Beer Engine Overview

## Beer Engine 2024

The Beer Engine is free, open-source brewing software that based upon percentage-driven calculations rather than physical weights and volumes. The calculations can be easily modified to meet the brewer's needs for volume, preferred units, and ingredient variations. Users enter their own values for volume and similar batch variables. The output is one-click for weights that meet the desired input. It's much easier to start with targets rather than hunting around to get the right weights for hitting your target.

## Concise version

The concise version has most of the recipe variables entered in a single field. Codes like m: for malt and h: for hops are used to code the recipe data. This version works nicely for recipes that are not meant to be altered. Examples would be published recipes or clone beer recipes.

## Flexstyle version

The FlexStyle version provides guidance for style-based recipe development. These meta-recipes are based upon BJCP style definitions, quantitative analysis from beer-analytics.com, and style guidelines written by experts. FlexStyle is a combination of "flexible" and "style."

## Make your own recipe calculator

People who have basic HTML skills can easily make custom recipe calculating pages with this software. The default values in the fields can be modified. This makes it easier to share beer recipes with other homebrewers. The Creative Commons license allows for free use of the software. Attribution is appreciated.
