1. Dry smoke: A good burley smokes dry and cool. One should rarely need the use of a pipe cleaner during the smoke and should have very little moisture when cleaning the pipe. 2. Nutty flavor: A good burley has a nutty flavor. It should never be bitter but instead should host a warm wood/nut-like flavor similar to that of a walnut. 3. Sweetness: Because there is no natural sugar in Burley, there should be very little sweetness, however, there should be a hint of it at times. It should be subtle and in the background. 4. Chocolate flavor: A good Burley has a slight natural chocolate flavor. It should be subtle and in the background but definately present. 5. Consistency: A good Burley should be consistent throughout the bowl. While the fullness should increase some, it should not become overwhelming nor grow weaker as the bowl progresses. 6. Clean Pipe: Good Burley should leave your pipe clean after smoking. This means no sticky residue on the walls of the pipe once you dump out the ashes.
Burley is a very underrated tobacco but many seasoned pipemen love it for it's natural charms.
