orientalxander-I don't know about the shelf life as I just started doing this. If left alone I'm sure it would be years but those are in 8 ounce jars and may get attacked before I have to worry about long term storage.
The Winslow is a hefty little dude and something I can't hold in my mouth without the aid of my hand...polygrip ain't the same as it was years ago or maybe my gums have shrunk. :mrgreen:
I'm not sure what to compare Autumn Evening with as yet, photoman. It's a cool, mild smoke for me and burns well but, I know tastes will vary. I haven't developed an educational palate like some that have been smoking the pipe decades. You should try it. I do like the Winslow. It has a larger airway and tenon than my others and the draw is effortless. I don't have the specs on it but the bowl is about 1 3/4" deep and diameter I.D. of 7/8" for long smokes.
Yep-those labels are made by hand by "Rip-a-Stickie in TN. :D
