A good mug requires good coffee, and then the Nybryggt.nu online store is a good source for refills.
The entrepreneur Karsten Deppert, who is behind Nybryggt.nu, has over 10 years of experience with coffee, including from the start of the Scandinavian School of Coffee (with barista training). Now there are both my mugs in two different sizes as well as milk jugs in their range.
