The stainless steel containers themselves do not absorb any odours. However, it is possible that with very odour-intensive foods, such as cinnamon sticks or cloves, the container lids and especially the silicone seals may absorb the odour/flavour.
If you grind coffee regularly and do not want to rinse in between, you are welcome to purchase an additional grinding container in our webshop, which you can then use exclusively for coffee beans.
