Cut off top: Use a sharp, serrated knife to cut about 1/2'' off the top of the pumpkin to create a lid.
Remove seeds: Use a large spoon to scoop and clean out all the innards and the seeds. Either discard or set aside to roast later.
Core and tap: Use a coring tool or knife to make a hole 2-3'' above the bottom of the pumpkin. Be sure to make the hole the same size as tap to prevent leaking. Insert tap through the hole in pumpkin. Secure and tighten locking nut on the inside.
Add beer: Add your beer of choice, making sure tap is in vertical position.
Use mini keg: Replace lid. Pull handle forward to dispense beer and enjoy!
