the ketchup smell didnt translate into the smoke
As Fred pointed out, it is not a topping or a casing, but simply the results of the aging process. If you don't smoke their blends, you are missing some truly fine Virginias.For years, some Pipe smokers have commented on the tin note of "ketchup", "vinegar", "barbecue sauce",etc from McClelland's Virginia blends. What that is comes from aging Virginia leaf that has not been stoved, or flue cured in cakes. It doesn't affect the flavor of the blends when they are smoked. If you take the blend out of the tin and allow it to dry a bit, this odor goes away.
So follow Fred's suggestion and take it out of the tin and let it dry out a bit. Then put it back. ::I have a half smoked tin of Beacon that just reeks and detracts from the enjoyment of the smoke .
