Stamp pressing is the only way to truly achieve cold-pressed oils. Nutritious foods made up of essential fats, nutrients, and minerals are necessary to be truly healthy. The natural balance of these nutrients is offered in natural stamp pressed oils, like those of Ulli's Oil Mill.
The machine presses seeds very gently and slowly so no frictional heat is generated as opposed to expeller pressing.
I press my oils in small batches on demand so the oils are as fresh as possible.
