I wrote the software that runs my own brew day.

Kettle Command is the app I brew with: the recipe, the mash and the boil, the controllers on the kettle, and the weeks of fermentation after.

It isn't a big company product. It's one brewer's tool that grew up batch by batch, and I brew with every page of it.

How it started

From milk jugs to a brewhouse that talks back

  1. 2010

    My first batch was Apfelwein in one-gallon milk jugs, under the bed. Then all-grain, and I never looked back.

  2. 2013

    Started BrewTech, the first version of what's here.

  3. Since

    Brew day pages, water chemistry, a yeast lab, inventory. Each one came from a brew day where I wished I had it.

  4. Now

    I build my own controllers for the kettle, and the app runs them. I don't weld, so metal parts get cut by SendCutSend and bolted together.

What it does

The parts I use every batch

  • Recipes that fit your gear. Scaled to your own batch size, efficiency and vessels, with gravity, color and bitterness checked against the style as you go.

  • A brew day that keeps up. Mash, sparge, boil, whirlpool and pitch with timers, targets and the next step, on the laptop or the phone.

  • Water, worked out. Salts and acid from your own source water to the style, with the mash pH before you strike.

  • Yeast you can plan around. Starters step by step, harvests, viability over time, and pitch rates for the batch you're brewing next.

  • Hardware that reports in. Kettle and fermenter controllers, probes, Tilt and iSpindel readings land on the batch on their own.

If you brew all-grain and this sounds like how you'd want to brew, ask for an invite. I read every one.
