    attenuationPercent fermentables kettleRetentionFraction? mashEfficiencyPercent ogEquivalent options?
    attenuationPercent: number

    Yeast apparent attenuation, %.

    fermentables: readonly FermentableAddition[]

    The grist and any sugars or extracts. Each ferments at its own rate.

    kettleRetentionFraction?: number

    Fraction of the kettle's wort that reaches the fermenter (0–1), default 1.

    This only matters when the recipe has fermenter additions. Some of the kettle sugars are left behind on the trub and the fermenter sugars aren't, so the yeast sees a mix slightly richer in the late additions.

    mashEfficiencyPercent: number

    Mash efficiency, %, needed to weight each addition's extract.

    ogEquivalent: number

    The OG-equivalent, which counts every sugar the yeast will see.

    options?: CalculationOptions

    Calculation options. Defaults apply to anything left out.
