The ??? may affect the openness of the tissue of the bean (deeper, wider) and thus the expansion of the coffee cake during brewing. - heard from a master in this forum.  |

IMHO,
Deeper the roast > wider the bean cellular gap> more water-bean contact > higher the solute yield rate (assume all other factors constant)
So it appears that lighter the roast, finer the grind (to obtain a constant yield)
Correct?
No, there is a fatal error.
The types and quantities of solute between a deep roast and a light roast (even of a same bean) are different, that optimal yield rate is not constant or same.
i.e. No strictly relationship.
Eventually, each batch should be tested separately as explained by Icarus.
