I recently received my first two corn cob pipes. I smoked Irish Oak out of one and Sunday Picnic out of the other. Both pipes yielded the same flavor, which I can only describe as bread and mushrooms. Confused, I smoked some Irish Oak out of a briar and did not get the same flavor as I did with the cob. Why did both cob smokes taste the same? I read somewhere awhile back that you don't need to break in a cob. Is that true? If not, is that why both cobs tasted like bread and mushrooms? Another possibility could be that both pipes came with a small paper cylinder lodged in the shaft and stem. For some reason I did not remove them for my initial smokes. Could that be the problem?
