Not an expert.

Some manufacturers adjust the blend depending on ring to keep the same taste.

Some manufacturers use the exact same blend everywhere, which means a different taste.

Some manufacturers adjust the blend depending on ring to give even more of a different taste.

Not much help, I know.

In general, however, the narrower the ring, the greater the impact the wrapper has on the taste. (This applies to the binder as well, but usually (usually) the binder is a light leaf chosen for good burning over taste contribution.) Also, some wrappers have more of a contribution to taste than others.

In addition, for Cuban cigars:
- below a certain ring, there is (supposedly) never any ligero (I can't remember the ring, 40 or 42).
- beyond a certain length, the cigar is blended milder, for example, a Double Corona is going to be blended to be a milder cigar than a Robusto of the same ring. (Again, I can't remember the dividing point - somewhere around 6 - 7").
