How to Interpret the Meilgaard Flavor Wheel
The Meilgaard Flavor Wheel, developed by Morten Meilgaard in the 1970s, has long been considered the beer flavor analysis standard by the European Brewing Convention, the American Society of Brewing Chemists, and the Master Brewers Association of the Americas. As an analytical tool, the flavor wheel covers a wide array of taste and aroma sensations that merge to produce what we know as flavor. The Meilgaard Wheel can assist the beer taster in targeting appropriate and inappropriate characteristics, but practical experience and knowledge is necessary to apply these descriptors to actual taste.
To illustrate my point, let us examine flavors found in beer that resemble fruit profiles. Fruity esters can be developed from the choice of yeast or due to fermentation temperatures. These flavors may also be the result of specific hop varieties, or may be enhanced by the direct addition of fruit, fruit concentrate, or orange rind. They may be the sign of an unfinished fermentation, as in the production of Ethyl Hexonate, that “green apple” flavor that forms before the final conversion into ethanol.
Describing the specific fruit will organize your thoughts and allow a more exact assessment. Review the following fruit profiles:
Dried fruit – raisins, figs, prunes, or thickened jam?
Tree Fruit – apples, pears, apricots?
Vine fruit – grapes?
Berries – black currants, boysenberries, raspberries, cranberries, blueberries, or blackberries?
Citrus – lemons, grapefruit, limes, or oranges?
Tropical Fruit / Melons – banana, cantaloupe, honeydew, pineapple?
Other – Fruit juice, artificial fruit concentrate, or frozen concentrate?
In the Citrus group, lemons signify the correct profile for Berliner Weisse but they may also signal the contamination due to poor sanitization or sick yeast when found in a beer of a different style; grapefruit is usually associated with hops from the Pacific Northwest; limes may be due to the addition of Madagascar chocolate, and oranges may be appropriate for Witbier. You can see that not only is it important to identify the specific fruit flavor, but you must also assess the flavor profile based on knowledge of beer styles and the brewing process. Becoming a Certified Beer Taster in the Beer Judge Certification Program takes study, practice and a keen ability to evaluate beer both in the scientific and organoleptic senses.
The Meilgaard Flavor Wheel is broken into taste and odor. Together, these constitute flavor, with odor playing an enormous role in what you perceive as flavor. By comparison, the 5 components that are identified on the tongue as taste are sweet, sour, salty, bitter, and umami, complicated by the “feel” on the tongue and within the mouth cavity – albeit, relatively simple compared to the complexity of the olfactory sense.
Keep in mind that the Flavor Wheel is a basic guideline, and you will need to spend some time thinking about what you can clearly identify, and what may confuse you. Something as common as banana may be perceived as melon or cooked vegetables by the untrained sensory evaluator. Different taste-buds may also interpret flavors differently. Some people have a specific gene that interprets coriander as "soapy," and have a tendency, therefore, to be put-off by anything containing coriander, even though it is the world's most widely consumed fresh herb throughout India, China, Southeast Asia, Africa, the Middle East, and Latin America. Seriously try to think of words that you may use to describe flavors in beer, using your imagination to enhance your skill.
