This is inspired by a post from @cerberus quoting Helmut Dönnhoff on riesling drinking periods, where Dönnhoff said "Riesling has two talents… I like it very young. It is wonderful to drink these wines young and fresh on a warm day. But don’t drink it all in the first two summers after the harvest. After 3 or 4 years the wine goes to sleep, and then after 6 or 7 it comes back. So I like it in the first two or three years and then after 10"
Clearly all wines evolve over time, some more desirably than others. But we sometimes talk of ‘dumb phases’ in this evolution, where the wine no longer expresses its youthfulness well but nor does it show much in the way of positive evolution. Anecdotally (i.e. based on my own reading), this mostly seems to be in the 4-8 y/o range. If given time, though, these wines come round and are good examples of more mature wines.
It seems some wines are more ‘guilty’ of this than others. I’ve heard of this several times for Northern Rhone reds in particular. The riesling example I think is discussed less often.
From a selfish perspective I’m interested in knowing others’ experiences with riesling in this respect, as it may inform to an extent when I withdraw some wines i have in reserves. Beyond that, I’d be interested to hear general perspectives on the idea of dumb phases, and wines which seem to experience this more clearly than others.
