> Many, possibly most, maple syrup producers in New England do not sell to national grocery store chains.

But scarcity is the problem. Unless you're able to demonstrate that the low supply is artificial, and that maple syrup producers are a cartel and restrict their own production and distribution chain, as well as block any newcomers from trying to enter large-scale production.

Because as is is, if they manage to sell their entire supply through their sugar shacks, then it obviously means they don't have enough capacity to supply grocery chains, let alone on a national level. That's the literal definition of scarce supply.
