|Maine wild heirloom raspberry|
I left Maine the following morning and got home 12 hours later. I was not surprised to see more liquid than solid in the bag. Without stopping to taste the liquid, I popped the berry bag into our home fridge.
The next day, I checked the bag and noticed it was full of little bubbles. Intrigued, I opened the bag, took a spoon, scooped out some of the liquid, and tasted it.
Ahh, it had changed. It was not a sweet syrupy liquid of pure raspberry sweetness. Instead it had turned into a bubbly beer like substance with just a hint of raspberry.
Then I remembered some information I read from The Everything Guide To Foraging book by Vickie Shufer that said all wild fruit have natural yeast on the outside of them.
So, if you have a chance to pick wild raspberries and don't want them to change into beer, wash them before you store them.
