WinemakerOS

Stop running oak, SO2, and blend decisions from whatever spreadsheet survives harvest.

Start with the calculator. Then set up the workspace if you want saved runs, Copilot help, and protocol drafts in one place.

The public side is built for concrete winery work: barrel-cost tradeoffs, SO2 math, blending checks, and trial planning. Built around cellar work, not a product demo.

Three fast ways to get value today

Start with the calculator or generator that matches the problem in front of you.

Barrel vs alternatives cost

See what oak format choices do to annual spend before you lock in another season of barrel cost.

Open

SO2 calculator

Set a target from pH and current free SO2, then translate it into a cellar-ready addition.

Open

Blending calculator

Model ABV, TA, and pH across lots before you move wine and create extra cleanup.

Where winery workflow usually breaks

Common places where time and wine slip through. Each one has a tool or template waiting.

Oak decisions made from stale pricing

Run the barrel cost calculator before you default to the same format mix out of habit.

Run cost calculator

SO2 adds made under time pressure

Check the math in-browser instead of trusting an old sheet no one wants to audit mid-harvest.

Open SO2 calculator

Bench trials that never turn into a repeatable protocol

Build a structured treatment matrix, timeline, and evaluation plan your team can actually run.

Honest tools for operators who can't afford to guess.

Every tool on this page is built around real cellar decisions: barrel cost, SO2 targets, blend checks, and trial planning. The workspace is optional — start with the calculators if that's all you need right now.

What you can actually use today

Public calculators run without a login.

Outputs are formula-based and visible in the browser.

Supplier directory pages include source links when available.

Calculators work without an account. The workspace is separate and optional.

Current setup path

Public calculators first. Workspace signup and winery setup second. If you need help deciding, book the setup call instead of guessing.

Three ways to start

Run a calculator now, set up the workspace, or start with a one-time Cellar Sprint if you want an implementation-ready protocol without committing to a monthly plan first.
