Your data stays on
your device. Always.

You're running a complex operation
with a notebook and a calculator.

Maple production has more variables than most small businesses — and most tools treat it like a hobby.

🗺️

No map of your bush

You know every tree by feel but when a new worker shows up or a line goes down, there's no reference. Everything is in your head.

📵

No signal in the bush

The internet is useless when you're standing next to a tap hole with a problem that needs answering now. Your expert needs to work offline.

🤷

No diagnosis

You know your yield is down but not why. Vacuum leak? Tree stress? Over-tapped zone? You're troubleshooting blind with no structured tool.

💸

Hidden waste and guesswork

Without RO tracking, DE calculations, and evaporation data, you don't know your real cost per gallon — or where to cut it.

📉

Boiling buddy sap without knowing it

Late-season sap can look perfectly clear in the tank. You don't find out it's gone to buddy sap until the syrup comes out dark and off-flavor — and it's already too late to pull your taps.

Put your entire
bush on a map.

SweetRun's Lines tab turns any satellite view into a live sugarbush map. Drop pins for every tap tree, tank, sugarhouse, pump house, junction, and waypoint — all saved to your device, no account needed.

Know before you
fire the evaporator.

SweetRun pulls the 7-day forecast for your exact location and scores each day 0–99 for sap run potential. It models freeze-thaw cycles, temperature swing, sunshine hours, wind, and precipitation — the same variables veteran sugarmakers read every morning.

Brix has dropped more than 30% from peak — buddy sap risk is HIGH. Syrup made now will be darker and may carry an off-flavor that drops your grade.
Tomorrow's forecast
Hi 54° / Lo 41° — Score 18 — No Freeze
🔥 Boil everything in your tanks today. Pull taps when buds start to swell.

Don't lose your
grade to bad timing.

Late-season sap looks identical to good sap — until you boil it. Buddy sap comes from trees that have begun to bud, and the syrup it makes is darker, cloudier, and carries an off-flavor that costs you your premium grade. You can't see it in the tank.

📉
SweetRun watches your Brix daily — log one reading per day and it plots the trend. A drop of more than 30% from your peak triggers a buddy sap warning.
🌡️
It cross-checks the 7-day forecast — if nights are holding above freezing, the season is over regardless of what the sap looks like in the tank.
🔔
You get the call early — boil what's in the tank today while you still have a run score worth acting on, and pull taps before buds blow.

SugarSage Expert System

40+ research-backed knowledge entries covering sap biology, vacuum, RO, evaporation, grading, tree health, and troubleshooting — sourced from UVM Proctor and Cornell Maple Program. Fully offline.

EXCLUSIVE
⚗️

Filter Press DE Calculator REBUILT

Enter your gallons and get your exact DE amount — straight mix or precharge method, early or late season rate. Step-by-step instructions with the right cup count baked right into each step. Beginner-friendly, expert-accurate.

NEW
📊

Season Recap + PDF Export

End-of-season summary with sap charts, Brix trends, year-over-year comparison, RO savings, and collection point breakdown. Print or export to PDF in one tap.

PREMIUM
💧

RO Savings Calculator

See exactly how many hours and pounds of wood your RO system saved this season versus straight-boil. Preheater modeled separately. Real numbers, not estimates.

🌡️

Complete Finishing Suite

Finishing temp by altitude, density check with temperature correction, Brix↔Baumé converter, syrup grade reference with legal Brix ranges, canning temperature guide. Everything at the finishing pan in one place.

🔧

Diagnose My Operation

Answer 9 questions about your setup and SweetRun ranks your top bottlenecks by ROI. Know exactly where your next investment pays off — vacuum, RO, spout sanitation, or tree selection.

Tap Rotation Tracker

Log which side of each tree was tapped each year. SweetRun tells you which side is due next season — protecting your trees and keeping yields high year over year.

⚠️

Buddy Sap + Brix Trend Alert KEY

Log a daily Brix reading and SweetRun plots the trend. When your Brix drops 30%+ from peak — and the forecast shows no more freeze — you get a buddy sap warning. Boil now, pull taps, protect your grade.

Stop guessing
your DE amount.

The rebuilt DE Calculator walks you through your exact setup — batch size, method, and syrup color — and gives you one clear number. Straight mix or precharge, early season or late, small batch or large. It knows the difference and adjusts for all of it.

Straight Mix
Mix DE directly into hot syrup. No precharge needed. Recommended for batches under 10 gallons.
Precharge First
Coat the plates with a DE-water charge first. Better for 25+ gallon runs and multi-batch days.
1
Enter your gallons — SweetRun auto-recommends straight mix or precharge based on your batch size
2
Select early/mid or late season — dark syrup carries more niter and needs a higher DE rate
3
Get your number: exact cups, ounces, and pounds — no mental math, no wasted DE
4
Follow the step-by-step instructions written for your chosen method — including the cloudy first-pour advisory for beginners
Also includes a Troubleshooting section — cloudy syrup, pressure spiking, flow stopped, and DE taste — written as "here's what to do right now."

🍁 40+ entries across 11 categories
Why does maple sap flow in spring?
Driven by freeze-thaw stem pressure — CO₂ dissolves at night creating tension, re-expands at day building up to 30 psi outward pressure...
My vacuum is lower than expected. How do I find the problem?
Systematic approach: isolate mainline sections one at a time, walk lines at dawn, inspect drop lines first — freeze-crack and UV brittleness cluster there...
What concentration should I target with my RO?
Most operations target 8–12°Brix for single-pass. Going above 16°Brix risks sucrose crystallization. UVM sensory studies show minimal flavor impact up to 16°Brix...

It pays for itself before the first run ends.

Identifying even one operational improvement — a vacuum leak, over-tapped zone, or wet wood problem — typically saves far more than $49 in a single season.
