That's us
Calistria is a licensed cannabis farm in Upper Austria, operated as an agricultural enterprise and recognised by the Austrian Chamber of Agriculture.
​
We work on-site with selected world-class hash genetics
not as a claim, but as proven practice.
​
Our focus is genetic selection, which we cultivate and evaluate together with partners. Modern technology is a tool for us; craftsmanship and precision are the foundation. Each plant is managed individually. No standardised copy-paste processes, no anonymous production.
​
Founded in 2021 by Julius Kretzschmar, Calistria is now positioned at the forefront of solventless-focused genetics in Europe. We collaborate with partners worldwide and maintain professional exchange with international actors in the scene.
In 2025, the work with partner Slite 23 was awarded 1st place at Masters of Rosin.
We see ourselves as a service provider for professional cultivators and producers of all scales.
Our role is to supply genetic material that performs under real-world conditions: in terpene profile, wash process, yield, and day-to-day handling. Not every cultivar has to do everything but every cultivar we offer serves a clear purpose.
Our vision
In the heart of Europe, where Austrian precision meets Californian innovation, Calistria was born. Our mission at Calistria is to bridge two worlds by making the finest cannabis genetics from California available directly in Europe.
Anyone can source genetics somewhere. Those who come to us know they want genetics that make a measurable difference. We work with individuals who no longer experiment blindly, but operate with intent.
Professional or connoisseur our vision is to place in your hands the exact genetics that position you ahead in the field, in the room, and in the final result.
We provide genetics for those who have already arrived.
Notice
The genetics developed and cultivated by Calistria are intended exclusively for lawful use.
Any further processing or extraction is permitted only in jurisdictions where such activities are legally authorised.
In Austria, our cultivation is conducted solely for legal, non-psychoactive, and botanical purposes.
