Hi Robert, Maple syrup can be cloudy due to the formation of sugar sand which, while not harmful and perfectly edible, can give your syrup a rougher texture and sweeter taste. This sediment forms during the boiling of the sap and is usually filtered out. When inadequately filtered or boiled after filtration, sugar sand may be left behind, or form for a second time in the container to produce a cloudy appearance. There's more about this (and how to fix it) here: https://blog.mapletapper.com/tag/why-is-my-syrup-cloudy/
