7 correct answers How many seconds should it take to fill a 16oz pint glass with 14oz of beer?
pH balance correct answers Which of the following is NOT a key component of draught system balance?
pH balance
Dynamic resistance
Static resistance
Applied pressure
Temperature
ideal correct answers The pressure at which CO2 is not diffusing from beer into the headspace and excess CO2 is not absorbing into the beer is known as the _________ gauge pressure
21 correct answers According to the table on page 39 of the DQM, which of the following would
be an INAPPROPRIATE setting on a pressure regulator for a beer held at 38 deg. F and carbonated to 2.5 vols of CO2 being dispensed with a 70% CO2 gas blend in Albuquerque (5,000 feet elevation)?
25
21
27
23
True
p.40 correct answers Nitrogenated beers must always be dispensed at a minimum of 30 psi.
T or F
False correct answers Adjusting gas pressure up or down is a good way to increase or decrease the flow rate of beer coming out of the faucet.
T or F
1/4 stainless @ 1.20 lbs/ft.
1/4 vinyl @ 0.85 lbs/ft.
1/4 Barrier @ 0.30lbs/ft.
3/8 vinyl @ 0.20 lbs/ft.
3/8 Stainless @ 0.12 lbs/ft. 3/8 Barrier @ 0.06lbs/ft
p.36 correct answers List the following types of tubing in order of highest dynamic restriction per foot to lowest dynamic restriction per foot: 1/4 stainless 1/4 vinyl 1/4 Barrier Tubing 3/8 Stainless 3/8 vinyl
3/8 Barrier
12 ft lift x 0.5 lbs = 6psi correct answers Using the industry standard approximation found in the DQM (we all like nice, round numbers, right?) there will be _______ psi of static resistance in a draught system where the faucet is 12 feet above the center of the keg being dispensed.
(Do not use a decimal point. Enter your answer as a number rounded to the nearest unit. Do not include units, which are included in the statement above)
3/16" vinyl tubing = 3 lbs/ft = R
14.5 + 3.5 (pressure adjustment for elevation) = 18 psi
static resistance = 0.5L = 0.5 lbs/ft (6ft) = 3 lbs
psig = partial pressure - static resistance
psig = 18psi - 3 lbs = 15 psi
L = psi/R
L = 15.5 psi / 3 lbs/ft = 5.2 ft
round down
5 correct answers Assuming that Example 1 on page 41 of the DQM is discussing a draught system located at sea level, an alternate solution could be found in Santa Fe (7,000 foot elevation) utilizing ________ feet of 3/16" vinyl restrictor line and no other diameter of tubing.
(Round your answer to the nearest whole unit. Do not include a decimal point. Do not include units, which are included in the statement above)
3/16" vinyl tubing = 3 lbs/ft = R
psi = LR
psi = 6ft (3lbs/ft) = 18 lbs (per square in)
3/8" barrier tubing = 0.06 lbs/ft = R
L = psi/R
L = 18 lbs/ (0.06 lbs/ft) = 300 ft
300 correct answers It would take ________ feet of 3/8" barrier tubing to equal the dynamic resistance of 6 feet of 3/16" vinyl restrictor line.
(round your answer to the nearest unit. Do not include a decimal point. Do not include units, which are included in the statement above). 45-55 deg. F
p.73 correct answers Which of the following is the typical temperature range for cask ale? 50-60 deg. F 45-55 deg. F 35-45 deg. F 40-50 deg. F
False
p.73 correct answers Cask ale is force carbonated at the brewery to between 0.9 to 1.2 volumes of CO2.
T or F
True
p.74 correct answers A swan neck style pouring faucet should always be submerged in the beer when pouring.
T or F
Beer Engine correct answers What is the name of the pump that pumps beer from a cask into a glass?
False
p. 74 correct answers After tapping, the top of the cask must be fitted with a pressure fitting to maintain headspace pressure and carbonation.
T or F
True correct answers Cask ale can be dispensed by simply allowing gravity to drain beer from the cask into the glass.
T or F
False correct answers Cask ale is usually served from stainless barrels, and rarely from wooden barrels.
T or F
True correct answers It is necessary to discard the beer left in a cask ale dispensing system on a daily basis at the beginning of every shift.
T or F
Re-filling glassware, and Unsanitary draught equipment correct answers Select EACH of the following that is detrimental to the quality of cask ale Refermentation in the cask
