Al --- There is absolutely no perique in Northwoods. It contains latakia, virginia, black cavendish, and (I suspect but am not certain) either some truly esoteric topping or some type of oriental leaf.
Countryside is delicious, and it IS similar to Northwoods, but perique isn't offered in any blends made by Boswells. In Countryside, the latakia is applied with a far lighter hand. Also, I suspect the base contains some burley and there is definitely a mild aromatic agent added. It's a quintessential "crossover" English/aromatic, while Northwoods is a very smoky, unique English mixture.
