Is anyone aware of websites that spell out
the effects of esters of various yeasts on
the aroma and flavor in wine?

Dick,

I pretty much stick to Lalvin; I like their yeasts. If you email a
specific question to Clayton Cone he gets back to you pretty quickly.
I would think Wyeast and Red Star would have similar sites, I think
the wine lab had something too. I think they speak in generalities on
purpose; it's hard to say what will really happen given so many
variables.

Dick,
I think little work has been done in this regard. Many of the academics
seem to feel yeast has only a small effect on the odor and flavor
characteristics of AGED wines. See "Principles and Practices of Winemaking"
by Boulton, et al

As some of you you know, i am too dang new to this to have my own
opionion, but i am reading fervently. But I happen to be reading on
this topic tonight. (What a coincidence)

I am reading "Modern Winemaking" by Philip Jackisch:
I just read Chapter 3 "The Composition of Wines"
Section Heading: "Odorous Compounds"
Page: 54
Quote: "Most of the esters found in wines of normal age are either
carried over from the grapes (or other fruit) or produced by yeast
enzymes during fermentation. When yeast stops growing, most ester
formentation stops"
