Details Genuine New Zealand Manuka Honey independently certified UMF 5+. Mount Somers Honey is proudly sourced from some of the most unpolluted and isolated areas of New Zealand and is GM Free. It has a uniquely rich, complex flavour and a distinctly smooth, creamy, velvety texture. Only the best Manuka honey brands have what it takes to be labelled as UMF certified, pure Manuka honey. Well established and world-renowned, this rating indicates the quality, purity, potency and strength of each individual batch of Manuka honey. The UMF quality mark assesses the key signature markers, confirming measured levels of methylglyoxal (MGO), Dehydroxymethylfurfural (DHA) and Leptosperin. Initially identified as the components giving Manuka honey its unique antibacterial properties, the UMF rating is directly linked to the amount of MGO found.
