Make your own wine aroma kit for practicing wine aroma description whenever you need to. You just need a base wine, different produce, spices or materials, and of course some time to plan ahead. The aroma references will have to be used within the next few days of preparation.
I found training for wine aroma identification more efficient when aromas are presented in a base wine, so to mimic a real wine tasting situation. I also found through my research that the training efficiency was higher when references were real products (e.g. real fruit versus an aromatic composition) or were real wines with distinct characters (see Sulmont et al, 1999).
Advice to make your own wine aroma kit
Select a base wine
How to choose the base wine? A base wine is by definition neutral, without faults, without strong aromas, tastes or mouthfeels. The best base wine I found for creating my wine aroma kits are in bag in a box, which mean you also have a large volume of the same batch to play with.
Prepare these wine references directly in a wine glass or in an hermetic container that you can store in the fridge if you don’t plan to use the aroma reference right away.
If you add pieces of products in the wine such for green bell pepper, let them macerate for 30 min to an hour and remove the pieces so that you don’t have any visual cues if you try to recognize these aroma references blind.
Use a “control wine” in your wine aroma kit, i.e. a wine without any addition to help you compare the wine without and with the aroma. It helps with the process of identification.
Below are some recipes for wine aroma references, borrowed from Dr. Ann Noble. Indeed, these references are a good complement to the wine aroma wheel.
Recipes for a homemade wine aroma kit
White wine common aromas
in 1 oz neutral white wine
Asparagus: several drops of brine of canned asparagus
Bell Pepper: tiny piece of bell pepper; don’t leave them in for too long
Vanilla: Drop of vanilla extract
Clove: One clove
Citrus: ~ 1 teaspoon of fresh orange and grapefruit juice
Peach: several teaspoons of peach or apricot puree or juice
Pineapple: 1 teaspoon juice
Honey: 1 – 2 Tablespoons
Red wine common aromas
in 1 oz neutral red wine
Asparagus: several drops of brine of canned asparagus
Bell Pepper: tiny piece of bell pepper
Vanilla: drop of vanilla extract
Clove: one clove
Soy sauce: few drops, great for older red wines
Berry: Fresh/frozen berries and/or jams
Berry jam: 1-3 tablespoons strawberry jam
Black pepper: few grains black pepper
Anise, black licorice: use few drops of anise extract
Sparkling wine particular aromas
In 1 oz neutral white still wine
Lime: a few drops of Rose’s lime juice or squeezed lime juice
Apple: Sniff freshly cut apple
Toasted hazelnuts: Crushed nuts alone
Sour cream/yogurt: 1Tbsp. in empty glass
Yeasty: 1 Tsp of Vegemite® or Marmite®)
Cherry/strawberry: few drops of flavored juices or extracts
Nutmeg: few grains
Caramel: crush one Kraft® caramel
Vanilla: as for table wines
Wine defects
In 1 oz neutral white or red wine
Moldy Cork: the BEST standard is the actual example of the defect. Save a spoiled wine which has a moldy odor, produced by TCA (trichloroanisole).
You can freeze the cork-tainted wine for future reference so that it won’t oxidized.
Oxidation: a few drops of sherry
Volatile acidity (VA) A few drops vinegar
Sulfur:
H2S Hydrogen sulfide, boiled egg or black sand from Japanese food store
Ethyl mercaptan: Smell of natural gas (tell people to experiment on their own carefully.
S02 Sulfur dioxideDried apricots (which were treated with sulfite)
Caution: Many asthmatics are very sensitive to it!
Brettanomyces is a wild yeast found in some wine: a drop of creosote or add a piece of old fashioned Band-Aid to create a horsy, sweaty saddle, barnyard smell
