When making pickles out of cucumbers the fermentation process is done within 7 to 8 days.
You'll know when the fermentation process of the cucumbers are done and they've turned into pickles when the pickles taste sour and the bubbles have stopped rising.
Then you can store the homemade pickles in the refrigerator for a few months and skim them as needed to keep them fresh.
The pickles should be ready to eat after 7 to 8 days of fermentation.
