Sensory Profile
Weissbiers feature fermentation by-products such as esters (which lend fruity flavors and aromas), especially isoamyl acetate, reminiscent of bananas, and the phenolic compound guaiacol, a metabolite of ferulic acid, which smells and tastes like cloves. Other phenolics sometimes found in Weissbiers evoke medicinal or smoky sensations. The bittering level of most Weissbiers is close to 15 International Bitterness Units, a relatively low level. Hop flavor and aroma are typically low.
The ester and phenolic aspects are produced by the special type of yeast, rather than the high fraction of wheat in the grain bill.
The carbonation level can range from 5.5 grams per liter (approximately 2.7 volumes; slightly higher than that of most other German beers) to 7 grams per liter, or more. This produces a generous stand of foam, especially in light of the high protein content of wheat malt.

Famous quotes containing the words sensory and/or profile:
“Ours is a culture based on excess, on overproduction; the result is a steady loss of sharpness in our sensory experience. All the conditions of modern life—its material plenitude, its sheer crowdedness—conjoin to dull our sensory faculties.”
—Susan Sontag (b. 1933)
“Expecting rain, the profile of a day
Wears its soul like a hat....”
—John Ashbery (b. 1927)
