When it comes to evaluating wine, your sense of smell is most important. Our ability to detect aromas is much more acute than our sense of taste, and wines contain thousands of scents and only a handful of tastes. More than 800 different aroma compounds have been identified in wines, making it perhaps the most aromatically complex food or beverage we encounter.
When describing wine, experts will often refer to aromas that include fruits such as lemon, peach and cherry; spices such as nutmeg and black pepper; vegetables or herbs such as green pepper and mint; and non-foods such as tobacco or smoke. Numerous chemical compounds are responsible for these aromas. Some compounds come from the grapes; most form during fermentation and some develop during maturation.
But what if, when you stick your nose in a glass, all you smell is … wine? How do you get better at identifying all the distinctive aromas that characterize the reds and whites you drink?
When they sniff a wine, experts activate their memory banks, comparing what’s in front of them with aromas they've experienced in the past. You can build your memory bank by carefully concentrating on the aromas you experience day to day, from the contents of your spice rack and refrigerator to the flowers and grass in your yard. You can also purchase a wine aroma kit to help you study.
But it’s easy, cheaper and even more effective to make your own set of aroma standards, using inexpensive wines and items you may already have at home or can pick up at your supermarket. You can enlist your local wine retailer to help you pick out neutral wines to serve as a base.
Once you have experienced known aroma standards in a neutral wine, you will find it easier to identify those aromas when you encounter them in more complex wines.

Hi Matilde.
Although kits can be helpful, stability is difficult to achieve and the aromas definitely have sell-by dates. The concentrations can also be an issue. I once worked on a kit with some aroma scientists and we ended up pulling some aromas. One funny story was about the TCA aroma, which is so pungent that we couldn't allow people to carry it on airplanes because, if it leaked, we might be liable for replacing all the upholstery!
> Cassis could be jam, which would be directional, or fresh cassis berries.
> For blackberry, I'd do frozen blackberries (unless it's blackberry season, which is all too fleeting).
> As for plum, there are so many varieties available fresh! I'd go ahead and crush a few ripe varieties together.
Happy sniffing!

Is it possible to keep the standards afterwards or do they go bad in a matter of hours?

A commercial aroma kit I purchased last year was a bust - only about half the vials had identifiable aromas and some were not usable for my seminars. I will try these DIY instead! What are your favorite ingredients for cassis, blackberry and plum?
