Happy Valley’s UMF® Manuka range is independently tested to meet both MPI Manuka classification requirements and the UMF Association’s purity and quality measures. We only put the best honey in our UMF® range from a minimum of UMF 5+, with a minimum MGO content of 83, up to our UMF 20+ and we control the full process, from bee keeping to processing and manufacturing. Happiness is homemade.
