The fair "Grüne Woche", which means "Green Week", attracts around 1,400 exhibitors from all over the world and several hundred thousand visitors.
Here, international and regional specialties are presented with a focus on organic food, bioenergy and sustainable cultivation of raw materials.
Värmland has several representatives at the fair - including chefs Christoffer Schyman and Robin Sundholm, who previously ran Almars Krog in Karlstad.
At the fair, they will present a hamburger with ingredients that almost exclusively come from Värmland producers.
- Hopefully it can arouse interest and lead to increased food tourism to the county, says Christoffer Schyman.
A couple of thousand hamburger buns made from custom flour have been baked and 200 kilos of local moose mince have been ground before the chefs can leave tomorrow.
Hear Christoffer Schyman tell more about his thoughts before the fair in the clip.
