Wow, so funny you should mention "old" Captain Black. About 30 years ago, I got it in my head to try pipe smoking. This was pre-Internet, and I didn't even know pipe smoking was considered a hobby. So I got myself a pipe from LL Bean and picked up a packet of Captain Black (Gold) at the local drugstore. I smoked it a couple of times over several years, and each time I got pretty severe tongue bite (that's a whole 'nother story). But I didn't stick with it, put it away in my car camping equipment box, and forgot about it. Early this year, I decided to try it again. Pulled my pipe and the same packet of now 30 year old Captain Black, stuffed the bowl, lit it up, and it tasted exactly as I remembered it, and it still gave me strong tongue bite.
Thanks to the folks on these forums, YouTube and talking with real tobacconists, I've since figured out how to avoid the tongue bite, and have enjoyed smoking up the rest of my ancient Captain Black tobacco. I understand the Captain Black brand isn't considered to be very quality tobacco, but I'm still a newbie, and could probably smoke pencil shavings with aplomb. Anyways, so funny to hear from independent sources that Captain Black "never dies," and remains consumable, just like Twinkies...
