Parti-Gyle Analyser 1.9

A Python tool for brewers to analyse historical Parti-Gyle brewing records and converts them into a scaled Single Gyle recipe (e.g., a 24 L batch) compatible with modern brewing software like Brewfather.

Features

• Parti-Gyle Analysis: Calculates Mass Balance, Pre-Boil SG, and Extract for multiple coppers (supports 2 or 3 copper setups).
• Advanced Calculations: Uses the Tinseth Formula for IBU and Morey Equation for Color (EBC/SRM).
• Single Gyle Conversion: Intelligently apportions ingredients from a complex multi-gyle blend into a single scaled recipe.
• Smart Scaling:
  • Adjusts for system Brewhouse Efficiency (e.g., scaling Industrial ~90% -> 24 L 72%).
  • Adjusts hop weights based on form (Whole vs. Pellet) and boil time changes.
• Detailed Reporting: Outputs a comprehensive text report, a JSON file, and a BeerXML recipe file suitable for import to brewing software. See examples>Output PA2

Prerequisites

• Windows 10/11
• Python 3.x installed (Ensure "Add Python to PATH" is checked during installation).

Installation

1. Download this repository (Code -> Download ZIP) or clone it:

   git clone [https://github.com/YOUR_USERNAME/Parti-Gyle-Analyser.git](https://github.com/YOUR_USERNAME/Parti-Gyle-Analyser.git)

How to Use

See the Tritun Books YouTube Channel for a more detailed explanation. https://youtu.be/siDEW_7H4g8

Prepare your Data: Create a JSON file describing your Parti-Gyle brews (see examples/ folder). Here you will find JSON for the 1975 Young's PA (Bitter and Special) both as a parti-gyle and as mulitiple gyles of the same beer - as shown in the Youtube video.

Run the Tool: Double-click run_analysis_1.9.bat.

Select Input: A file dialog will appear. Select your JSON file.

Select Target: If multiple beers are defined (e.g., PA1, PA2), select the one you want to brew from the popup list.

Save Output: Choose a folder to save your results. You will be prompted for a filename [BeerName]. The tool will generate:

• [BeerName].txt: A human-readable report of the analysis, blending, and a recipe.

• [BeerName].json: A JSON version of the recipe file.

• BeerXML Export: Automatically generates a standard [BeerName].xml file for direct import into Brewfather, Beersmith, and Grainfather. Ready for editing to suit your system. [Note Only tested with Brewfather]
