Sap & collection
Active taps
The number of taps actually collecting during a run — often fewer than your total count (pulled taps, dry holes, vacuum leaks).
Why it matters
Recording active taps per collection keeps your per-tap yields honest, so seasons and locations compare fairly.
Brix (°Bx)
A measure of sugar concentration — the percentage of dissolved sugar by weight. Sap typically runs 1.5–3 °Bx; finished maple syrup is at least 66 °Bx.
Why it matters
Logging brix tells you how much syrup your sap can make and helps you spot strong and weak runs across the season.
Flow window
A stretch of hours when weather favors sap flow — typically after a hard freeze, thawing into the 30s–40s °F.
Why it matters
The forecast highlights flow windows so you can plan collection and boiling before the sap arrives.
Freeze–thaw cycle
A night below freezing followed by a day above it. Each cycle recharges stem pressure and restarts sap flow.
Why it matters
Seasons with many cycles produce more sap; the forecast counts them to estimate what your season has left.
Sap flow
The movement of sap in a maple, driven by freeze–thaw cycles: freezing nights build pressure, warm days release it through the taphole.
Why it matters
Understanding flow helps you predict good collection days and plan crew time around the weather.
Sap temperature
The temperature of sap at collection time.
Why it matters
Warm sap grows bacteria faster, which darkens syrup and risks off-flavors — cold sap buys you processing time.
Sugar content
How much sugar your sap carries, measured in brix with a refractometer or hydrometer.
Why it matters
Higher sugar content means less boiling per gallon of syrup — it drives your yield and fuel costs.
Tap
The hole drilled into a maple each season, fitted with a spout that sends sap into tubing or a bucket.
Why it matters
Tap counts are the base unit of your operation — forecasts, yields, and lease terms are all figured per tap.
Production & grading
Density
How concentrated finished syrup is, measured in °Brix — legal syrup must reach minimum density (66 °Brix in most jurisdictions).
Why it matters
Under-density syrup can ferment and is illegal to sell; over-density wastes yield and can crystallize.
Invert sugar
Sucrose that has split into glucose and fructose during the season and the boil — it rises as sap ages and microbes work on it.
Why it matters
Invert levels affect flavor, color, and how syrup behaves in value-added products like candy and cream.
Syrup grade
The color and flavor classification for maple syrup: Golden, Amber, Dark, or Very Dark.
Why it matters
Grades trend darker as the season warms; logging grade per batch helps you match production to what your buyers want.
Yield ratio
Gallons of sap needed to make one gallon of syrup — roughly 86 divided by sap brix (the “Rule of 86”).
Why it matters
Tracking it shows how efficiently your operation turns sap into syrup, and how sugar content moves through the season.
Bottling & traceability
Lot
A batch of packaged syrup you can identify and trace — typically one bottling run from one source of bulk syrup.
Why it matters
If a problem ever surfaces, the lot is what lets you recall one batch instead of everything you’ve sold.
Lot genealogy
The family tree of a lot: which barrels filled it, which boils filled those barrels, and which collections fed the boils.
Why it matters
One-step-back, one-step-forward tracing is exactly what food-safety rules and organic audits ask you to show.
Mass balance
A reconciliation of inputs and outputs: sap collected, syrup made, bulk stored, retail packed, and sold should roughly agree.
Why it matters
Certifiers use mass balance to test recordkeeping — a clean one is direct evidence your traceability holds together.
Tubing
Lateral line
The small-diameter tubing running tap to tap, feeding into mainlines.
Why it matters
Lateral layout — length, slope, taps per line — sets how well vacuum reaches each tree.
Vacuum leak
Anywhere air enters a tubing system — chewed lines, loose fittings, failed seals — dropping the vacuum level.
Why it matters
Every inch of vacuum lost costs measurable sap; leak-checking during flow pays for itself.
Compliance
Evidence
The document, log, or record that proves a requirement is met — a lead test result, a training record, a cleaning log.
Why it matters
Inspectors don’t take your word for it. If it isn’t written down, it didn’t happen.
Inspection pack
A ZIP binder Sapline assembles per program: your documents, records, and readiness evaluation, organized the way an inspector expects.
Why it matters
When the inspector calls, you hand over one organized binder instead of digging through drawers.
Qualified facility
An FDA/FSMA status for smaller operations (based on sales and who you sell to) that carries simplified food-safety requirements.
Why it matters
Most maple producers qualify — but you must attest annually and keep records proving the status.
Readiness score
The share of a program’s required items your operation currently satisfies.
Why it matters
It’s not a pass guarantee, but a low score reliably points at gaps an inspector would find.
Requirement
One item from a program’s rulebook — a document to hold, a practice to follow, or a record to keep — with its regulatory citation.
Why it matters
Programs are just checklists of requirements; working them down one at a time is how readiness climbs.
Business & records
Break-even
The syrup price at which a season’s revenue covers its recorded costs.
Why it matters
Knowing your break-even by container size shows which sales channels actually pay.
Cost category
A grouping for expenses — sap purchases, fuel, equipment, labor, packaging, and the like.
Why it matters
Categorized expenses turn a shoebox of receipts into a cost per gallon you can actually act on.
Expense
Any money out of the operation: supplies, fuel, repairs, lease payments, labor.
Why it matters
Logged against the season, expenses are what turn your production numbers into profit numbers.
Import review
The step where you check each row read from your spreadsheet or photos before it saves.
Why it matters
Nothing lands in your records without your approval — fix or reject rows right in the review.
Maintenance interval
How often a piece of equipment needs service — hours run, seasons used, or calendar time.
Why it matters
Tracked intervals catch the vacuum pump rebuild before the best flow week, not during it.
OCR extraction
Reading numbers and dates off photos of paper logbooks automatically.
Why it matters
Years of handwritten records can join your data without retyping a line.
Profit estimate
Season revenue minus recorded costs — computed from your sales and expense records.
Why it matters
It’s only as honest as your cost logging; missing expenses make thin margins look fat.
Service log
The record of what was done to a machine and when — repairs, rebuilds, filter changes, calibrations.
Why it matters
Service history is what inspectors ask for and what resale buyers pay for.
