About this Exam
Prepare with the Beer and Wine Exam 2 Practice practice quiz. This question bank includes 10 questions covering barley, typically, lager, beer, and wine. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.
Sample Questions
Question
1
What common off-flavor can result from contamination, and how can it be prevented?
Explanation:
Microbial contamination is a common source of off-flavors, often showing up as sour, funky, or solvent-like notes. Bacteria such as lactic acid bacteria and wild yeasts like Brettanomyces can infiltrate a batch and produce lactic acid and other compounds that give a sour or barnyard character, while metabolic byproducts can also create solvent-like aromas. Because these flavors arise from organisms growing in the beverage, the best defense is preventing their entry and growth in the first place and limiting the time they have to affect the product. Thorough sanitation and proper cleaning of all equipment, gear, and packaging, careful handling to avoid contamination, and good storage practices are key. Consuming the product within a reasonable timeframe helps minimize the window for any potential microbial activity to alter flavors.
Question
2
Which hop variety has citrus aroma characteristics?
Explanation:
Amaro is chosen because its aroma profile is distinctly citrus-forward, especially orange and citrusy notes. This comes from its essential oils, which give a bright, zesty citrus character when used for late hop additions or dry hopping. The other hops tend toward different flavors—Target brings spicy/herbal and resinous qualities, Cluster is milder with earthy/ woody notes, and Progress is less citrusy and more balanced—so Amarillo best fits a request for a citrus aroma.
Question
3
Which statement about volatile acidity is accurate?
Explanation:
Volatile acidity refers to the volatile acids in wine, mainly acetic acid, along with related compounds. These give vinegar-like aromas, a sharp, tangy note that you can smell even at low levels. At higher concentrations, acetates and related solvents can produce a smell reminiscent of nail-polish remover. Aromas described as nutty or caramelized come from other chemical processes and components, such as oak aging or Maillard-derived compounds, not VA. The burnt-matches smell comes from sulfur compounds, which are unrelated to VA, and VA is detectable by smell rather than being odorless.
Question
4
6 row barley has lower diastatic power than 2 row barley.
Explanation:
Diastatic power is the malt’s enzymatic ability to convert starches into fermentable sugars during mashing, mainly due to enzymes like alpha- and beta-amylase. Six-row barley varieties have been bred to have more enzymatic activity, so they typically show higher diastatic power than two-row barleys. That extra enzyme capacity helps in mashes that include unmalted adjuncts or require stronger starch conversion. So the statement that six-row has lower diastatic power than two-row isn’t correct. While diastatic power can vary by cultivar and malting conditions, the general trend is that six-row provides equal or greater diastatic power.
Question
5
Typically, yeast grows under aerobic conditions in the first hour or two of fermentation.
Explanation:
True. At the start of fermentation, yeast needs oxygen to build essential cell components and to grow quickly. Oxygen is used to synthesize sterols and unsaturated fatty acids, which are critical for forming robust cell membranes and for cell division. Brewers typically aerate the wort at pitching so the yeast enter an aerobic growth phase, often lasting the first hour or two, before they switch to anaerobic metabolism as sugars are consumed and ethanol is produced. So the early aerobic growth is the normal pattern, making the statement accurate.
