For your son's birthday, you can consider getting him a fermentation kit. This will allow him to enjoy creating different kinds of fermented foods and beverages, such as kombucha, kimchi, sauerkraut, yogurt, etc. Another great option could be a book on fermentation that features unique, creative, and innovative recipes. If he already has a fermentation kit, you could opt for quality ingredients such as organic or locally grown vegetables, starter cultures, or a temperature control device that will help him to achieve the perfect fermentation environment.
Or you can get him a star map with the date when he was born.
