Batch any cocktail. Get the dilution right.

A shaken or stirred single picks up water from the ice. A batch poured from a bottle or pitcher does not, so multiplying a single-drink recipe by the guest count produces a drink that is too strong and out of balance.

A batch is not a single-drink recipe times ten.

Batching needs a dilution calculation beyond scaling the recipe: how much water to add before serving. Without that number, a batch can be too strong, over-diluted by melt, or out of balance.

Pourcent calculates the dilution water that helps a party batch taste like a freshly made single.

A single-drink spec in, a party batch out.

Start from a recipe.

Pick a Negroni, Manhattan, Daiquiri, Margarita, or Old Fashioned template, or build a custom spec with parts, ml, oz, or jigger and ABV.
Choose the drink family.

Select stirred, shaken citrus, built or highball, or punch. Each family sets a sensible default dilution.
Size the batch.

Set the batch by servings, 750 ml bottles, or total base volume.
Read the batch.

See every ingredient scaled, the water to pre-batch in, and the estimated final ABV.

Built for the person making the batch.

The one calculation that matters.

Pourcent uses the final-volume method — finalVolume = baseVolume / (1 − dilutionFraction) — to calculate dilution water and estimate final ABV.

Pourcent questions.

How does Pourcent calculate the dilution water for a batch?

Pourcent uses the final-volume method: finalVolume = baseVolume / (1 − dilutionFraction). It applies the target dilution for the selected drink family, finds the finished volume, and shows the water to pre-batch in alongside the scaled ingredients and estimated final ABV for that batch.

Can I size a batch by servings, bottles, or total volume?

Yes. Size a batch by the number of servings, by 750 ml bottles, or by total base volume. Pourcent scales each ingredient from the single-drink spec and includes the calculated dilution water in the batch output for the amount you choose.

Does Pourcent handle stirred, shaken, highball, and punch drinks?

Yes. Choose stirred, shaken citrus, built or highball, or punch. Each drink family provides a sensible default dilution, which Pourcent uses when calculating the final batch volume, the water to add, and the estimated final ABV before you prepare the batch.

Does Pourcent estimate the final ABV?

Yes. Pourcent estimates the final ABV after scaling the ingredients and adding the calculated dilution water. The estimate describes the finished recipe, not a person’s response to it, and should not be used to judge impairment, blood-alcohol content, or driving readiness.

Is Pourcent a subscription?

No. Pourcent is planned as a $2.99 one-time purchase for iPhone, with no subscription or in-app gates. It works fully locally, with no backend, network calls, accounts, or analytics. Saved batches, notes, and share text stay on-device.

Does Pourcent estimate impairment or blood-alcohol content?

No. Pourcent scales and dilutes cocktail recipes and estimates the finished recipe’s ABV. It does not estimate a person’s impairment, blood-alcohol content, or driving readiness. A responsible-hosting disclaimer is always present; use Pourcent for recipe planning while serving guests, not safety decisions.
