A process for sure, but the end product is just so good and all natural. I think the best part of making the syrup is that the entire process is done outdoors. Collecting the sap is my favorite part. It always amazes me when I return to check the jugs, and 12 hours later the gallon bottles are full.
The sap is cleaner than any water you can find anywhere. I keep at least a gallon from every run just to drink.
