Selling fermented goods without a permit does raise serious health concerns. But the ethics aren't just about the permit itself; it's about ensuring your products are safe for others. Permits exist to make sure you follow basic food safety rules, which protect customers from getting sick. You could look into what it takes to get a permit, even if it means starting on a smaller scale. Being upfront about your process and testing your products can also build trust. Have you checked with local health departments about what they require?
Remembered a buddy who sold pickles at a farmers market without checking the rules. His whole batch grew mold because he didn't get the acidity right, something a basic food safety course would have covered. He had to throw everything out and refund people, totally killed his side hustle. Felt bad for him, but it showed why those steps matter.
