The De Troch Brewery is a historical landmark.  Because of this, the yeasts and bacteria found at De Troch are under Belgian government protection. As a result, these precious creatures cannot be genetically modified or updated for the 21st century.  We at SpontanAir are not even sure if harvesting them and removing them from the property is a violation of these protections.

Buy these soon, as their export may be severely limited in the near future!
