I finished Nose Dive yesterday. What a fascinating tour de force! It took McGee over ten years to write it. I certainly learned a lot. But a caveat: it's not a page turner as with a novel. It's partly a chemistry book with some narration. I can see it as an reference book that can be referred to as needed or if you're curious about some odor.
Here's a quoted tidbit for you wine lovers:
"Wines can end up with undesirable smells, which include an excess of volatile acidity in the vinous bouquet or of the sweaty-saddle volatiles produced by Brettanomyces. Musty, dank cork taint is caused by fungal growth on chlorine-disinfected cork stoppers. In smoke taint, grapes exposed to smoky air detoxify the phenols and guaiacols by bonding them to nonvolatile sugars; later, grape and yeast enzymes release them during fermentation, as do mouth microbes during drinking! Ladybug taint is a green-pepper, asparagus smell that results when too many of those helpful insects end up crushed along with the grapes. Then there's fruit-fly taint: if you see a fly overcome by the bouquet of an open glass or carafe, fish it out quickly! Female drosophilia carry a waxy-floral aldehyde as a pheromone to attract males, and can leave a detectable off-odor in the glass within minutes."
