Comparing on-site preservation techniques for fresh Welsh birch sap for use in artisan products by local businesses

This project is taking place across four sites in Wales and will focus on three different production methods and will analyse which method is most effective at turning birch sap into a concentrate at different scales of production.

  • Outdoor wood stove: The sap is boiled down in evaporating pans to a sugar concentration of below 20%.
  • Reverse osmosis: The sap is pushed through a vacuum pumps and micro-porous osmosis filters which brings the sap down to around 15% sugar concentration.
  • Urn: An electric thermostatically controlled urn heats the syrup and reduced it to a sugar concentration of below 20%.
