Maple Syrup Calculator

Maple Syrup Calculator is a set of 15 single-purpose calculators for the people who actually run the boil — built for cold hands, a steaming pan, and no signal in the sugarhouse.

THE ONE YOU'LL OPEN EVERY BOIL DAY

Syrup finishes at a fixed distance above the boiling point of water, and water's boiling point moves with the weather. Working from a memorized 212 °F is the most common reason a batch finishes off density. Tell the app today's conditions and it gives you the exact temperature to pull at.

Three ways to set it, whichever suits your setup:
• Read your phone's barometer live
• Type today's barometric pressure
• Enter the boiling point you measured in the pan — the most reliable of the three

FINISHING
• Syrup finish temperature, corrected for today's pressure
• Hydrometer correction — true Brix from a hot or cold test
• Thin or thick fix — how much water to add, or how much to boil off
• Blend batches — combine two batches and land on target
• Sap to syrup — gallons of sap per gallon of syrup, corrected Jones Rule

PLANNING
• Boil time — hours, fuel and cost before you light it
• RO savings — hours saved concentrating
• Season projection from your tap count
• Taps per tree from trunk diameter
• Pan capacity — match a rig to your taps, or taps to your rig

PACKAGING AND MONEY
• Bottle counts — what a batch fills across your container sizes, with a slider per size
• Weight — volume to weight and back
• Cost and pricing — cost per gallon, break-even and target price

CONFECTIONS
• Cook temps for cream, candy and sugar, corrected for today's pressure
• Sugar yield — syrup in, granulated sugar and molded candy out

BUILT FOR THE SUGARHOUSE
