I brewed a pale ale and kegged it. I have always did the "burst" technique, and has always seemed to work. However this batch will not carb. I did about 30 psi for 48 hours, then dropped it to 12psi for 5 days. I drew a pint and it had just a hint of carbonation. So I checked my seals and did it again still nothing. I am no physicist or chemist but I do know Boyle's law that the gas should be forced in. But could there be some chemical reason in my ale that will not allow the carbonation? I am about ready to crank up my regulator as high as it can go! BTW the ale tastes great even flat, so I am super eager to get some effervescence!
