He's heating it before filtering. Heat to a boil and filter hot into a warm jar. It will cool before it hits the filter and leave the nitre behind.

This is not hot packing prefiltered or settled syrup. In those cases stay under 190 to avoid creating post-filter nitre.

@ Big_Eddy....Oh OK gotcha, makes sense :-)

@ MapleLane1...attaboy! And have LOTS of paper coffee filters on hand, even if you leave the bulk of the nitre behind. Nitre is harmless to ingest, btw, it's full of minerals.

FWIW when I reheat syrup (which I have already filtered the nitre out of) to only 185, and heat glass jars or jugs. in the oven, set to heat at 190 for 10 min. Then, using something like a pair of Duramax gloves, I take them out and use a clean funnel to fill them with. This gives the jars a chance to cool and not be hot enough to form nitre in the jar with the hot syrup.

If using Mason jars, fill only to the shoulder (leave headroom at the top) and use clean new pop-top lids and yes they should make that noise as they seal down.

If I have a batch that is really super-nitrey and hot filtering it doesn't seem to work, I'll filter syrup cold (well room temp, not fridge cold) It is a painfully slow process, but then I have perfectly clear syrup to reheat and thus am not worried about nitre. So once you've drawn off all your clear cold syrup and left the nitre behind, you could include this step so you don't need to filter at the bottling stage but expect it to take some time...like usually overnight!!

Good luck and let us know how it goes.
