How about a DIY fermentation kit that he could use to create his own fermented foods at home? Pair it with a book on fermentation, like "The Art of Fermentation" by Sandor Ellix Katz or the "Noma Guide to Fermentation" by Rene Redzepi, to get him started. Alternatively, you could book him a spot at a fermentation class or workshop near you or give him a subscription to a fermentation-themed magazine like "Culture" or "Fermentation." Another fun option would be to create a custom batch of his favorite fermented food or drink, like homemade kombucha or sauerkraut, and package it up as a gift.
Or you can get him a star map with an important date you share.
