I bought some Davidoff Grand Cru No. 3s in late 2020. When I smoked the first one in spring 2021, it tasted like a light cigarette to me - almost no flavor . After resting for another year I found that it had developed a nice profile.
More recently I purchased a Davidoff 2022 LE. Had a lot more body than the first Grand Cru I smoked, but same sort of thing where it didn't really have much of a profile. I would hope, especially given the $34 price, that they would improve over time.
