I discovered yesterday that 4 oz hex jars take considerably more than 4 oz of honey if they are to be filled properly. I’ve had an order for 250 and this is the first time I’ve used jars this small. By my calculations 4 oz of honey is 113.5 g. The closest I could get was about 115 g on my scales, which left the honey surface a few millimetres short of the shoulder of the jar. Very unsightly. If you follow the advice for filling standard 1 lb rounds, ensuring there isn’t a gap below the lid and the surface of the honey, then you actually need to add about 140 g of honey to fill these small jars.
These jars were supplied by Compak who indicate they have a volume of 116 ml. Perhaps my honey is particularly dense? The jars are attractive and make nice gifts. Just make sure you prepare sufficient honey to fill them properly. My initial calculations of needing 62.5 lb of honey (i.e. two slightly overfilled 30 lb buckets) for the 250 jar order is out by about 15 lb.
