I stumbled across this company while looking for a seller of Gruut Inferno. The company has a small store in Geleen and a distribution center in Puth, where they ship to local restaurants. The store, in my opinion, is not really worth it. It’s pretty small and the person working the desk did not know any English. You can get more selection at other stores, like Drankenhal Corstjens.
The distribution center has strange hours but we eventually were able to talk to one of the employees. The minimum order is half of a case (12 bottles), but they are willing to order anything that is on their distributors list. The service was quick too. I asked for the order on a Saturday, they ordered it on Monday and it was in my hands on Wednesday.

The building is white and does not look like a store. Street view on Google Maps has a accurate picture. You can park on the left side of the building and ring the doorbell for service.
