MGS 20+ Manuka Honey 250g / 500g

  • Harvested from remote pristine areas in New Zealand
  • Dark amber in colour with aromatic & flavoursome characteristics
  • Molan Gold Standard graded


The Manuka tree is native to New Zealand and Watson & Son select areas around the country which are remote, pristine and abundant with Manuka to position their beehives. 

This MGS 20+ Manuka Honey is a dark amber colour with aromatic and flavoursome characteristics.  Watson & Son believe in respectful, sustainable ethical practices with minimal intervention to help preserve the purity of their honey.

To guarantee a high-quality product, every batch of Watson & Son honey is tested and certified to meet the stringent standards required for Manuka Honey.  Watson & Son use the MGO (Methylgloxal) and their own MGS (Molan Gold Standard) measurement standards in their Manuka Honey grading.  Both recognise the unique levels of MGO in each jar of their product, so you can buy with confidence knowing that the MGS 20+ and the equivalent MGO 800 readings are accurate.  Further guarantee of an authentic product is knowing that Watson & Son trace their honey through all production stages - from the hives to the end product.  Watson & Son certified MGS Manuka honey is available in grades from  MGS 10+ through to MGS 20 +.  Higher grades signify higher concentrations of the unique Manuka Honey compounds and potency.
