Homebrewing
This section of CraftBrewer.se covers everything about homebrewing — from the science of why equipment and chemicals behave the way they do, through guided brew-day walkthroughs, to a growing recipe collection.
There are three parts:
The Brewer's Manual is a data-driven reference covering materials science, chemical compatibility, equipment analysis, and processes. It works from primary sources — safety data sheets, EU food contact regulations, peer-reviewed chemistry — and either confirms or challenges conventional homebrewing wisdom with evidence. The core thesis: here is why you probably don't need to worry, and here is the specific scenario where you might.
BrewClub is a guided programme for new brewers. It takes you from your first brew through progressively more advanced techniques in a linear, step-by-step format. Each stage links into The Brewer's Manual when you want to understand the science behind the recommendation.
Recipes is a shared collection covering fresh wortWort Liquid extracted from malted grain during mashing and boiling, before fermentation. The starting point for beer. kit splits, extract and partial mashMashing Soaking crushed malted grain in hot water at a controlled temperature to convert starches to fermentable sugars. brews, and all-grain recipesCIP — Clean-in-Place A method of cleaning the interior of pipework, vessels, and equipment without disassembly, using pumped cleaning and rinsing solutions. Standard in commercial and microbrewery settings. Requires dedicated CIP equipment and is out of scope for small-batch homebrewing. — all designed around the BrewClub equipment list and scalable to larger setups.
About this guide
AI assistance
This documentation was written with the assistance of Claude AI. Claude was used as a research assistant — helping to fill gaps, stress-test reasoning, and structure conclusions — and builds on several years of personal research and brewing experience. All content has been reviewed by humans and should continue to be reviewed by humans. AI makes mistakes; so do humans; the goal is to catch both.
Open source
This is an open source document. You can contribute on GitHub — by writing new documentation, correcting existing content, or simply raising an issue if something looks wrong.
The one non-negotiable guideline: everything must be backed by a reputable source. Gut instinct alone does not qualify. Personal experience that supports or contradicts what is written here is genuinely welcome — describe it, and if it can be corroborated, it will strengthen the guide.
This guide exists to challenge received wisdom and confirm or bust the myths that circulate in homebrewing communities. All contributions that meet the evidence standard are welcome.
Where the evidence is strong, this guide says so. Where it is uncertain, inferred, or pending manufacturer confirmation, that is stated explicitly. Absence of documentation is not evidence of safety — and this guide will not pretend otherwise.
