Discover De Proefzaak!


De Proefzaak is a place where people come together, to meet each other, to enjoy life… and enjoy our beers!

In the middle of the Amsterdam Southeast, between grey concrete office buildings, you’re able to find a green hangar surrounded by a bit of nature: a green oasis in a concrete jungle. It is here, where the only beer of the Bijlmer is brewed by Brewery Kleiburg. It is a real monastry beer, connected to the Kleiburg monastry.

You are very welcome to visit ‘De Proefzaak’, our tasting room next to the Brewery. Where you can taste our unique beers with a view on the brewery.

The best local products

De Proefzaak only uses fresh, local and fair trade products. We work toghether with PuurDichtbij, who deliver right from the farmer to De Proefzaak. That’s better for you, the environment and better for the farmer. 


Kleiburg beer

More than just a beer..

The name Kleiburg is more than just a beer brand: read about our story, the monastry and of course our unique craft beers. 



In De Proefzaak we serve delicious sandwiches for lunch or snacks with a drink.

We believe it is important to use local, fair and sustainable products.
