Since Hermosas are a Corona Gorda size, maybe the factory screwed up and put the Red bands on some that were meant to be the new Brown band CG Reserva??? Either way, those definitely look dark, and good.
They are old, came from a box 2007. I never pay attention to the red tats when at the b&m and saw these today. Smoked 1 and it was fantastic, then grabbed the last 2. Wish I would have saw them before.
I would guess that it's just natural variation. I"ve noticed a dramatic difference in the color of the brown line over the years: SW's that look like they're connecticut wrapped, Tainos that look maduro, etc... Enjoy!
