My Miskatonic University Blend is only 1% Latakia. That's a suprise to most people who try it, but it's just there to round out the flavor and enhance the smoothness.
I notice very little difference between the tinned and bulk BH. Russ put a lot of effort into makign it that way. If you stuck them both in jars, in 3 months, I doubt even the most discerning would be able to tell which was which.
