The bouquet of the wine is a fancy way of saying how the wine smells. The smell of a wine is often as important as how the wine tastes because smell can heavily influence the taste of a wine. If the bouquet shows aromas that are "off" or simply do not smell good, this sensation will carry over onto the palate.
Often times, the bouquet of a wine can tell a story. Is the wine grassy and herbal with grapefruit characters? In this case, you may be smelling the delicious aromas of Sauvignon Blanc. Or what if the bouquet has a heavy black pepper aroma followed by hints of raspberry and blackberry. These are the sure signs that you've run into an aromatic Zinfandel.
The point here is to take your time. Swirl,
sniff and smell. Gently hold the base of
your glass flat on the table and take time
to swirl the wine around in the glass,
coating the entire bowl. This will add a
thin layer of wine to the glass, releasing
another layer of the wine's aromatics.
Hold the glass up to your
nose tipping the wine slightly toward your
nose and deeply inhaling. Don't be afraid to
get your nose down into the glass - the
deeper you go the more aromas you'll pick
up. Try to identify specifics in what you
are smelling. Do you smell fruit? If so,
what kinds? If you're having trouble picking
up a specific fruit, trying writing down a
few adjectives that do come to mind.
Remember, the more smells you expose
yourself to, the better trained your brain
is to recognize those smells later. Taking
notes on the wines you smell, helps get your
brain in shape for all those long hours of
sniffing!
Finally, remember that your sense of smell can be effected by outside influences. If you try to evaluate the bouquet of a wine in a Chinese food restaurant, you may pick up different smells in the wine - or perhaps, all you'll smell is Chinese food. The point is that your environment can dramatically effect the bouquet and aromatics of a wine.
