AI Homebrewing Companion for Claude | Beer Recipe Calculator and Brew Day Log | Digital Download

Hit your numbers. Brew beer you're proud of.

Brew Day turns Claude into the brewing buddy who loves the math. Design a recipe to style with every number calculated, get a clock-time brew day plan, sort out your water and mash, nail fermentation and carbonation, and work out what that off-flavour is and how to avoid it next time.

This is a digital download of AI skills for Claude, the AI assistant by Anthropic. A skill is a set of expert instructions you add to your own Claude account. Nothing to print, no app to learn.

WHAT'S INCLUDED
• Recipe design to style
• Scaling and extract conversion
• Timed brew day schedule

TRY ASKING
"Design a hazy IPA for my BIAB setup." "What's my strike temperature?" "How much priming sugar for a saison?"

HONEST ABOUT WHAT IT DOES
• Formulas shown: Tinseth, Morey and gravity math, so you can check every number.
• Safety built in: Burner ventilation, CO2 cylinders, bottle pressure and cleaning chemicals.
• Process before recipes: Sanitation and temperature control come first, because they matter most.
• Legal homebrewing: For adults, for personal use. It won't help with distilling.

HOW IT WORKS
1. Download your 3 files right after purchase (2 skill ZIPs and the Start Here PDF).
2. In Claude, open Customize, then Skills, click +, choose Upload a skill and pick each ZIP. Keep them zipped.
3. Start a new chat and ask: "I brew 5 gallon all-grain batches in a bag. Design me a crisp pale ale and give me a brew day timeline."

WHAT YOU NEED
• A Claude account (claude.ai). The free plan works: turn on code execution in Settings, Capabilities.
• This is a digital file. No physical item will be shipped.
