The True Honey Co. 850+ MGO 20+ UMF Manuka Honey is authentic New Zealand Manuka honey, independently tested, certified 850+ MGO / UMF 20+ and traceable back to the land block that produced it. This rare, high rated 850+ MGO Manuka honey has a luscious, resinous sweetness. The slight tingle you feel at the back of the throat is a mark of its very high concentration of Manuka. As this is a product direct from nature, slight flavour or colour variations are part of its beauty.
