Blend Ratio Calculator

When to use this blend calculator

Use this when you are planning trial blends, scaling a successful bench sample, or checking whether your component volumes can reach a target batch size. It is especially useful when the blend looks simple in percentages but awkward in litres, gallons, or bottles.

Keep every component in the same unit before comparing totals.
Treat the result as a production target, then confirm the final blend by tasting.
Leave a small margin for racking losses, topping wine, and measurement error.

Blend planning notes

The calculator assumes the two lots mix evenly and that volume change after blending is negligible. In practice, trial blends should still be tasted side by side because aroma, tannin, colour, and texture do not always follow a neat weighted average.

For production work, keep a written note of the component volumes and the reason for the blend. That makes it easier to scale a bench trial, repeat a successful lot, or adjust the blend after lab results come back.

How to judge a blend result

A blend ratio is not a tasting note. It tells you whether the basic chemistry and volume plan are plausible before you pull samples or move wine. If the target ABV is only reachable with a tiny amount of one component, the blend may be mathematically possible but impractical to execute cleanly in the cellar.

Use the output to plan a bench trial, then taste the trial before scaling. Aromatics, tannin, colour, and texture do not average as neatly as alcohol or sugar. Keep notes on the component volumes so a promising glass sample can be recreated at batch scale.

Use the same volume unit for both components.
Check that the target ABV is between the two component ABVs.
Allow a small margin for racking loss, topping wine, and measurement error.

Blend math should support tasting

Ratios are useful for keeping trial blends organised, but the best blend is not always the mathematically neat one. Once the calculator gives a volume plan, make small bench trials and label each sample clearly before scaling up.

When moving from trial to batch, keep the units boring and exact. Convert everything to millilitres or litres, label each component, and keep a written blend sheet. The best use of blend math is repeatability: being able to remake the sample that actually tasted best.

Best use

Converting target percentages into measurable volumes for trials or batches.

Do not skip

Tasting order, bottle variation, stability checks, and careful notes on every sample.

How It Works

This calculator blends two components using weighted-average calculations.

Set optional target ABV to compute ratio guidance.
Review resulting blend ABV, acidity, sugar, and target-ratio output.

FAQ

How are blend metrics computed?

ABV, acidity, and sugar are computed as volume-weighted averages.

Why can target ratio be unavailable?

If target ABV is outside the range of component ABVs, no feasible two-component ratio exists.

Can I model more than two components?

Use iterative two-component passes or external blending sheets for multi-lot optimization.
