@ehBeth,
how do you know. Our laws say the same thing but its almost impossible to detect without an on the spot density and refraction test.
Many syrup farms display their densitometer and RI numbers per 40 gal "batch". They do a better job than the Pa Dept Ag (which for the US is one(if not THEE one) highest ag testing and reg'd for food safety).
NEVER bought anything sugary from states like Mississippi or Arkansas . Sugar content can be screwed with so many ways.
