Using the funnel, add the pumpkin puree and pumpkin pie spice to the bottle.

Next, fill the bottle with homemade kombucha. Store the bottle in a dry place out of direct sunlight.

For 4 days, burb (or crack the lid to let air out) the bottle once a day (ideally over the sink). After the 4 days, refrigerate the kombucha and enjoy once chilled. Keep refrigerated.
