カクテルレシピ・バッチ計算ツール

計算の仕組み

Every ingredient is stored in fluid ounces and simply multiplied by your serving count, then converted for display at 29.5735 ml per ounce. Ten recipes are built in, from the 2 / 1 / 1 oz Margarita to the equal-parts 1 / 1 / 1 oz Negroni. Ingredients recorded as zero ounces — mint leaves, orange peel, a lime wedge — render as "to taste" with a multiplier rather than a volume, so they never inflate the batch total.

Servings scales linearly up to 500 and the Output unit select toggles millilitres or ounces. The pre-dilution slider runs 0 to 30 percent, defaulting to 20, and adds a chilled-water row so a bottled batch drinks like one stirred over ice. It fires only on the four stirred recipes flagged for dilution: Old Fashioned, Negroni, Manhattan and Dry Martini. For everything else the note tells you to batch the concentrate and add citrus fresh.

Moving that slider does nothing at all on the other six drinks, which is deliberate but entirely silent — no label greys out and no message explains it. The recipes are one fixed house spec each, with no way to edit an ingredient, adjust sweetness or add your own. The batch total is liquid volume only, taking no account of ice melt in the glass, bottle headroom, or the strength of what you have poured.
