Barrel Aging Calculator
Estimate volume loss from angel's share during barrel aging based on starting volume, barrel size, aging duration, and climate.
Cuts Calculator
Estimate heads, hearts, and tails volumes from your distillation run based on wash volume, ABV, and still type.
Fermentation Yield Calculator
Estimate the expected ABV and alcohol volume from fermentation based on wash volume, sugar concentration, and yeast efficiency.
Gauging Calculator
Calculate temperature-corrected proof from an observed hydrometer reading using simplified TTB gauging tables. Standard reference is 60°F.
Mash Bill Calculator
Calculate individual grain weights for your distilling mash bill based on total grain weight and percentage of each grain type.
Proof & ABV Converter
Convert between proof, ABV (alcohol by volume), and specific gravity. Supports US proof and UK proof (Sikes).
Spirit Dilution Calculator
Calculate how much water to add to dilute a spirit from its current ABV to a target ABV for proofing down.
Spirit Infusion Calculator
Calculate ingredient weight and infusion time for flavoring spirits with vanilla, fruit, spices, or herbs at your desired intensity.
Still Output Calculator
Estimate the volume and ABV of distillate from your still based on wash volume, wash ABV, still type, and collection efficiency.
Tincture Strength Calculator
Calculate herb and solvent quantities for making tinctures at your desired strength ratio and batch volume.
