I like the maple syrup I make... Started with a dozen taps 5 years ago and I've got the equipment with capacity for about 1500 taps just not enough time to get the lines run.. So I'm still doing 20 taps for personal use each year..
But I've got quite an education in Maple Syrup over the last several years...
The flavour various from year to year based on a bunch of things..
SAP
- Location of the trees
- health of the trees
- Sugar content or the trees
- what the sap runs
- collection method
- storage method
- storage length from collection to processing
Processing
- Evaporation method
- Heat source (if wood wood type)
- Temperature of evaporator
- Temperature
- Relative humidity
- Filtration method
As well as the time from evaporation to packaging, the temperature its packed at the packaging itself and and finally how it's stored..
All true syrup is at least 66 brix. Syrup from the same trees can be good one year and lousy the next... Tasting your sap is a good idea....
Sap is affected by sunlight, exposure to air, anything it comes into contact with...
