Mash Bill is an idle tycoon game for iPhone in which you run your own bourbon distillery. Choose mash bills, distill new-make spirit, fill barrels, and rick them in your rickhouses. Barrels age on the real-world clock — whether the app is open or not — until you sample, blend, bottle, and sell your releases.

A craft of patience. No ads, no in-app purchases, no account — and it plays completely offline.

Features

From Grain to Glass

Run every stage of a working stillhouse. Queue a batch and the cooker, fermenter, and still work automatically while there’s grain and space.

Three mash bills to start — Traditional, High-Rye, and Wheated — plus custom recipes of your own
Multiple stills, fermenters, and tanks as your distillery grows
Column, doubler, and pot still conversions that change your output proof
Buy grain from the farmers’ co-op, or set up grain contracts to reorder automatically

Aging Is the Game

Barrels keep aging on the real-world clock, even while you’re away. Waiting is the craft.

Choose each barrel’s char level, entry proof, and floor
Bottom floors lose less to the angel’s share; top floors pick up oak flavor faster
Wood-clad, masonry, and climate-controlled rickhouses change how each floor behaves
Free sampling reveals flavor, quality, and traits — every barrel has a peak, and waiting too long can cost you
Rotate barrels between floors, and finish them in stout, port, sherry, or toasted oak casks

Blend, Bottle, and Label

Select a single barrel or blend several, set your bottling proof, and name your release.

The label review shows exactly which classes your blend qualifies for — Straight Bourbon, Bottled-in-Bond, Small Batch, Single Barrel, and Barrel Proof
Bottling makes whole 750 ml bottles and records each release’s age statement and provenance
Name your distillery and see it on every new label

Sell and Build a Reputation

Fill orders on the Market board for cash and reputation
Stock distributor shelves that keep selling while you’re away
Enter the Limestone Awards and compete for medals

Grow Your Distillery

Add cookers, fermenters, stills, and staff, with construction that finishes even while you’re offline

Mash Bill is made for adults. Every distillery, brand, buyer, and label in the game is fictional. The game is about making whiskey, not drinking it, and does not depict or encourage drinking.
