Cavendish is the process used to add flavors to tobaccos. Lane's HS - 3 features natural Cavendishes which are cased with a slight vanilla flavor. Likely, Burleys are used to make those Cavendishes. This process smooths out the Burleys and makes for a very mild smoke. This is the perfect all day, very mild tobacco blend.
In my pipe bowl, HS - 3 [known as Brookwood in the shop] tasted vanilla-y and nutty. The nut flavor confirms Burley was used for the Cavendish in this tobacco blend. I did not get a lot of the vanilla though. I found only smooth, very mild tobacco. I'd recommend this for anyone looking for an all-day, unobtrusive smoke.
