How it works

  1. 1

    Say what you want to drink

    Type it, paste an old recipe, or snap a photo of a beer label. Ask for a hazy with Citra and Mosaic, a clone of a stout you love, or "something for a hot afternoon on the porch."

    Chat with the Beer Builder: a request for a hazy IPA and the builder's reply explaining the recipe
  2. 2

    Tune it like a brewer

    Sliders for strength, bitterness, color, hop emphasis and finish. Every move recomputes OG, FG, IBU, SRM and water, and the style check shows you the moment you drift out of range.

  3. 3

    Brew it this weekend

    Every ingredient is checked against live inventory. One click puts the grain (milled or whole), hops and yeast in your cart. Print a shopping list and a brew day sheet with strike water and mash steps.

What is different about it

Only recipes you can actually buy

In-stock mode designs from what is on the shelf right now, so there is no "sorry, out of stock" after you have dialed the beer in. Flip to All Ingredients when you want the whole 1,900-item catalog.

Real numbers, not vibes

The AI proposes, a brewing calculator does the math. OG, FG, ABV, IBU, SRM, strike temperature, mash steps and water chemistry are computed, not guessed, and every edit recomputes them.

Your kettle, not a generic pot

Profiles for Clawhammer all-in-ones, Anvil, Grainfather, BrewZilla, Spike, kettles and coolers, or enter your own volumes and efficiency. Volumes and strike water are figured for your rig.

It remembers

A free account saves your recipes, equipment, water profiles and the ingredients you already own. Reorder any past brew straight from its brew day sheet.

Already keep recipes in Brewfather or BeerSmith?

Export them and drop them in. Each one comes back priced with in-stock ingredients and ready to reorder, with your notes and equipment along for the ride.

Questions brewers ask

Is it really free?

Yes. Design and tune recipes as much as you like. A free account lets you save them and lifts the guest limits. You only pay if you decide to buy ingredients.

Do I need Clawhammer equipment?

No. Pick from 67 profiles covering most home systems, or enter your own kettle volumes, losses and efficiency and the recipe is figured for it.

Can I use grain and hops I already have?

Yes. Add them under My Ingredients and the builder designs with them. Buy only what you are missing.

Where do ingredients ship from?

From our warehouse in the United States, to US addresses. Grain ships milled or whole, your call.

Does it work on my phone?

Yes. Build on your phone, save the recipe, and open the brew day sheet at the kettle.

Your next brew day starts with a sentence.
