01
In the sugarhouse
- Draw-off temperatureToday’s boiling point of water plus the offset for 66.0 or 66.9 °Brix. Measured, or estimated from elevation and the weather report.°F
- Hydrometer correctionCorrect a hot Brix or Baumé reading to 60 °F, or see what the hydrometer should read at this temperature. With a printable card for 66.0 and 66.9.brix
- Sap to syrup yieldHow much syrup your sap or concentrate will make from its Brix, by the revised Jones Rule of 86 (UVM Proctor, 2013). Gallons and pounds, at 66.0 or 66.9 °Brix.gal
- Drum weight and conversionsGross less tare to gallons at the syrup’s Brix, plus gallons, litres, pounds, and kilograms, and Brix to Baumé to specific gravity.lb
02
Density, grade, and blending
- DilutionDetermine how much water to add to bring syrup to the desired density. For diluting with sap, use the density blending calculator.brix
- Density blendingBlend two syrups, or syrup with water, sap, or concentrate, to a target Brix. Proportioned by weight, not volume.brix
- Grade blendingBlend a light and a dark syrup to a target light transmittance. Works in absorbance, so it doesn’t under-call the light syrup, and takes a measured 50/50 reading if you have one.grade
- Invert blendingBlend two syrups to a target invert sugar level for maple cream, candy, or granulated sugar, by the rule of allegation.%
03
Tanks and lines
- Tank volume and dipstick chartGallons in the tank from the depth on the stick, the weight of what it holds, and a dipstick chart to print and tape up.gal
- Tubing line volume and sanitizerWhat your laterals, drops and mainline hold, and the sanitizer concentrate to fill them at the manual’s strengths.gal
04
Plan the season and the sugarbush
- Season syrup potentialStart hereEstimate how much syrup you might make this season from tap count, sap per tap, and average sugar content.gal
- Vacuum tubing benchmarkStart hereEstimate mainlines, laterals, tubing footage, and pump CFM from a conservative University of Michigan vacuum tubing model.inHg
- Tap leaseCompare a flat per-tap rent, the land-rent method, and a rent tied to the bulk price: what the landowner gets and what each tap costs you.$/tap
05
Cost, price, and sell
- Cost per gallonAdd up a season’s costs, including depreciation and your own time, and divide by the syrup you made. Shows the arithmetic line by line.$/gal
- Sap buy priceA price per gallon of sap from its Brix, the bulk syrup price per gallon or per pound, and the seller’s share.$/gal
- Syrup retail pricingRetail prices for every container size from the bulk syrup cost plus container, cap, label, and labor, with markup and margin side by side.$
- Value-added productsWhat a batch of syrup makes as sugar, cream, candy, or jelly, what each package costs, and the price that gives you your margin.lb
