Dark fired is burley, and it seems true of burley that some pipe smokers can't taste it, and others who can, find it unpleasant, as in regurgitating. But for many others, burley is a full flavored and complex smoke. A Forums member sent me a sample of Mac Baren's Old Dark Fired, and I found it flavorful and vibrant. So I bought a ladder of dark fired blends. So far I haven't gotten back to ODF, but I'm looking forward to it. Dark fired has been around for quite a while, but it seems to be used now more as a flavoring leaf, like Latakia and Perique. If you have a taste for burley, it's a fine smoke. For others, I guess, it's pretty dreadful. It's a different experience for various people.
