It depends whether you bought your your sampler at a BM or online, if at a B/M that would explain the great taste
Ignore: sorry could'nt resist....
I've found Padrons to be very consistent, regardless of where they come from.
A couple posters mention the differences between the taste of the 64' and 26series... I dont find them to be that much different. I find all Padrons have a similar taste.... I'm lucky, I can smoke Padon 0000 series and not feel like Im missing out on a thing...
