Just a heads up to all. I recently kegged around 3.5 gallons of pumpkin ale and bottled another gallon or so using the Brewers Best carb tabs (these are the little ones). Well, I would agree with all of the negative reviews. After 3 weeks we popped them open and experienced a very skunky, flat beer!! Dumped all the bottles out! The kegged portion was execellent however.
