I have come across a few random trees around town that have some tiny fruits on them, still trying to identify what they are. I really would like to start fermenting almost anything I can get my hands on for free, more for my amusement than for making a delicious beverage. What have you all fermented from the wild? Are there any famously poisonous trees/shrubs that I should avoid? Hopefully I can post a pic of what I have found later today. Thanks for any input.
