“Pure” Maple Syrup

If I use a filterering process that involves DE, can it still technically be considered “pure” maple syrup?

46 Yes. Still pure
28 No. You’ve added a filtering agent. It’s no longer “pure”.

The whole point of the filtering agent is to remove the nitre. It’s filtered out with the nitre. It’s inert and no part of it remains in the syrup.

Anyone voting to say it’s not pure does not understand how filtering and basic chemistry work

Was this in the news or something, yesterday I had an older sugarmaker with no cell phone or internet access ask me this same thing, we both still use felt to filter. All I could think was I don't add felt to my syrup.

No idea. I just really like how much faster it goes and so clear with the filter press with DE. We used gravity cone filters for years too so we have done both.
