Every Powstanie I've tried has been good. The San Andres tasted like a strong blended stick (as opposed to smooth if that makes sense) with earth and spice and that San Andres maduro flavor, and perfect construction the whole way. Very enjoyable, but I do think the strength of the blend might have overpowered the wrapper a little bit. Something like Stolen Throne Crook of the crown lets the San Andres wrapper shine a little more IMO by way of contrast if you've tried those. The Powstanie comes off more like a Nic puro even though there is Dominican in there.
I think I've enjoyed the habano blend the most so far among the few Powstanie I've tried; I had that in the perfecto size I think it was. That's on my list to grab a few of at some point, but they seem harder to find.
Definitely a brand I want to explore more of as well.
