I love my olive wood pipes. I have found that they do smoke as good or better than many of my briars. Some people have claimed that they imparted an olive oil type taste to some of the tobaccos. I have not found that to be the case. Plus, as stated earlier, I love the grains that appear in Olive wood. They are quite stunning. Smokey in nature and character. If interested, you might want to check out Abi Natur. He is a heck of a guy who makes stunning Olive wood pipes from trees on his own family land. Canaan pipes is his brand.
http://www.canaanpipes.com/ I have pictures of the pipe he made posted in a thread on here. I think you can look it up to see if interested.
He is the nicest guy.
I am looking forward to buying a morta to try. I have another thread on here that discusses Morta as well.
