number 1 - "maple syrup" isnt all just maple syrup.
Please tell us what maple syrup is if not 100% maple syrup.
it means that maple syrup varies in colour/flavour based on tree type, year, time in the season (early, mid, late), sugar concentration after boil etc. you could have maple syrup boiled down to 80g sugar/100g or left at a light 40g sugar/100g
there i explained it to you (plural).
just like "malt" isn't malt
