It is unadulterated honey from nature and as such it will react to temperature and storage variations.  Crystallisation in Berringa Honey is not uncommon and it can easily be remedied by heating the honey (and the jar it is in) slowly in a bowl of hot water – or leaving it in a hot room/place.  Do not microwave it though as that will simply see it re-crystallise quickly after.Crystallisation is natural, safe and not a sign of mould spores or anything else untoward.Better by BerringaEstablished in 1992, Berringa is a family owned company passionate about Australian Manuka Honey.We source from bees that feed on Leptospermum plants in wild, pristine coastal areas of Eastern Australia.These are ideal conditions for superior quality bioactive Manuka with natural enzymes.Berringa is part of the Australian Safe Quality Assured BSQA - 0047www.batch.com.au
