As good as Larry's Blend is, Black House is superior, IMO. I don't know whether its the Kentucky or what, but something in it just sets it apart.
I agree, though I am not a fan of Larry's Blend (sacrilege, I know
)
I think I like BH so much because, to me, the latakia is subdued. According to Russ Ouelette, who created Black House to replicate a 25 year old Balkan (the original Balkan Sobranie, IIRC), Russ was trying to develop the blend so that the latakia component was as it would be in the very well aged original -- mellow, sweet, lightly smokey.
Even using Cyprian, not Syrian, and the challenge required, I think Russ hit a home run with Black House. I am not a huge latakia fan, but I really enjoy Black House.
