In terms of flavoring, Grousemoor is Grousemoor. The exact same flavor/scent is used on both the plug and the mixture. However, apart from one being a plug and the other a mixture (duh) there is another difference: the base tobacco is different. Grousemoor Mixture is a bright, yellow, sweet, light bodied Virginia blend. Grousemoor Plug is deep, rich brown, also sweet, pure Virginia but with a heavier, smoother flavor (less bite potential also) and a touch stronger to boot. It's not STRONG per se, but a solid medium compared to the mixture's mild bodied nature. Grousemoor Plug is Kendal Plug with Grousemoor scent/flavoring added. Kendal Plug is unsliced Best Brown Flake, so if you've tried that it should give you a frame of reference. So for a medium bodied, sweet plug, go for Grousemoor if you want that nice citrussy, springtime field and lemongrass taste, or go for Kendal Plug if you want an all natural blend. I really like the flavor of 1792 Flake, but I don't care much for SG's presentation of flakes. I think I would therefore LOVE their Cob Plug, which is unsliced 1792. I could slice it as thin as I wanted. The Cannon Plug is also supposed to be good, but I haven't tried it. Basically, I think it's going to be harder to find a plug that's bad than to find one that's great. Much harder. It's an old fashioned presentation, and it's "harder" to work with. There's good reason it's far from the most common presentation. People like to be able to open a pouch and just dig in. So the old plug blends that are still being made are most likely still around because they kick butt in most cases.
