Someone in a local honey show had the squat 1lb ones and they looked nice (to me).
Well, the retail perception of honey is changing and the 454g is going out of favour for good reason: in olden times honey was sold and marketed as a cheap food in a big jar, and in some timeless areas it's easy to find a 454 on sale at a farm gate for £3.
In other words, they're virtually giving it away and reinforcing in the customer mind that honey should be cheap, much as supermarket honey is cheap, but hang on, that is also cleansed, pastuerised, possibly diluted with syrup and without flavour or identity.
We produce a food that bears no relation to the supermarket product: ours is unprocessed, local, direct from the producer, and
we must regard it as treasure and sell accordingly.
If we agree that our collective aim is to increase the public perception of honey as a quality food, then we must stop selling at a low price in a big jar. However, although you must take the customer with you when raising prices (slowly, over a few years)
jar size can drop today.
For example, if I sell a 235 (your 8oz) for £6.55 it follows that a 454 (your 1lb) would cost £13.10, at which price my customers would walk away. To achieve my price level the largest jar I use is a 340 (your 12oz) at which point my honey will cost £9.50, and because it hasn't broken the £10 barrier, won't scare away trade.
Try this: park a 454 next to a 340 and you will find that both are large jars. Either will satisfy a customer, who will anyway be primed to accept 340s as supermarkets have long used this as their large size for many food products.
The place for the 454 is in a honey show where old-school regs must be followed, but if your fellow beekeepers are selling in the same size then they're living in the past. No harm in that, except that such practice will suppress the price and fail to support the new generation of beekeepers who wish to raise the value and perception of honey.
