Crumbs ... at the rate things are going the labels on some honey are going to take over so much of the jar you won't be able to see the honey - which in many cases sells the product more than the label.
I can't see any reason for a '
consume within x weeks' addition to the label. Even if the customer leave the lid off it's not going to ferment for a week or two at least and the first things TS are going to ask is how long ago did you buy it, have you got a receipt and how has it been stored ?
Worrying about such matters is nonsense ... Selling fermenting honey - well, that's a different kettle of fish. But even if you have fermenting honey as long as you state it on the label it's OK to sell it - there is small but growing market for fermented honey. (Can't say I fancy it ... but some people do !).
