Hi Peck,
I don't know the specifics beyond cut, and color of the blend. I haven't bought any since 2015 or maybe 2016. The people talking about it I've learned to trust when it comes to tobaccos.
This does seem consistent with what I'm seeing from other blends produced by K&K and others, especially with the substitution of Perique with Dark Fired in several blends I do smoke regularly.
I'm pretty much done with buying anyway, not totally, let's get real, but I'm only buying maybe 10% of what I used to buy when I was stocking up. So most of this doesn't affect me, except when I purchase something to replace usage only to find out that it's been subbed. So I'm not even going to do that. I'll just smoke down the pile and maybe pick up a few tins of something new that looks interesting..
Perhaps some others can shed some more light on this.
