Hello - newbie here. This is my first time syruping on me own. I live in NE MN and tapped 23 trees this spring. I made just under a gallon of syrup this spring using a homemade set up consisting of a 55 gallon barrel and two stainless steel pans with 6 gallon capacity. I filtered my sap multiple times both before boiling, as well as after taking it off the wood fire before bringing it into the house to finish up on the stove. Now that the syrup is bottled, I noticed a decent amount of niter sand has accumulated on the bottom of the jars. How can I filter this again to remove the niter sand? I tried using a coffee filter and that didn't work as barely any syrup moved through the filter in 30 minutes. Any suggestions would be greatly appreciated.syrup boiler.jpg
