House of Fermentation
House of Fermentation is a Korean fermentation company on the Jan Hanzenstraat in Amsterdam Oud-West, making kimchi and other Korean fermented foods and selling them from its own shop.
The kimchi follows a family-style recipe from Jinju in South Korea, with 23 ingredients and no sugar, and it is made vegan by using replacement ingredients. Where the vegetables come from is not yet confirmed.
The shop is open on Tuesday from 14:00 to 18:00 and Wednesday to Saturday from 10:00 to 18:00. You can also order online or take out a kimchi subscription. The kimchi comes in glass jars that you swap for full ones on your next order, which their website describes as a zero-waste sales cycle, running since 2018.
They also teach kimchi fermentation workshops that walk through the method step by step, along with its history.
