He turned 89 this year and his website calls it 'aged root briar'. He started stocking piling old briar in the 1960's as prices continued to rise each year. He makes wonderful pipes.Never heard of Dunhill using this, but Julius Vesz purports to make every pipe from dead root briar. Most experts say that the phrase "dead root briar" is simple marketing ploy that is used to sell pipes. I don't know if Vesz is still alive, but he'd be at least 90 years old. He makes/made marvelous pipes. Lives in the Toronto area.
