Wine aroma and flavour wheels

Wine aroma and flavour wheels can be helpful in identifying the smells and tastes that appear in varios wines for various reasons. Our Rondo from two years ago had the distinct smell of acetone, which stems from bacterial contamination. Our Solaris this past summer produced a wine with depth and complexity that was difficult to pinpoint. In both cases, the wheels may help us describe each vintage to its full advantage. 

I find the UC Davis chart hard to read. 

There are any number of sources of the wheel, each with slightly different descriptions. Of course, it can be a chart and not a wheel. 

I like this one. It's easy to read.
