Draft Systems And Storage Flashcards
What is the name of the part that automatically stops the flow of beer when the keg empties?
FOB (foam on beer)
How often should draft lines be changed?
Once every two weeks 
When must an FOB detector be reset?
After changing the keg
If draft lines are not cleaned regularly, which flavors are most likely to develop?
Butter and oiliness, vinegar
If one of the draft lines is pouring foamy, what are two potential causes?
Temperature of the keg is too high
Kink in the coupler / wall hose
Why must draft lines be cleaned regularly?
To prevent bacterial infection
To limit oxidation while maintaining beer quality, what is the optimal temperature range for beer storage?
35-45 degrees
Beer stored at room temperature for several months is most likely to develop which flavor?
Paper and wet cardboard
What beer attribute is fixed in bottled beer but can be affected in draft beer?
Carbonation
How many gallons is a 1/2 barrel?
15.5 gal
How many gallons is 1/4 barrels?
7.75 gal
How many gallons is 1/6 barrels?
5.15 gal
When does non-pasteurized draft beer expire?
45-60 days
When does pasteurized draft beer expire?
90-120 days
When does bottled beer expire?
Six months refrigerated, three months non-refrigerated
What percentage of light does brown glass block?
98%
What percentage of light does green glass block?
20%
What kind of packaging best prevents skunking?
Cans
Ceramic bottles
Bottles in closed case boxes
What is a party pump and why is it detrimental?
Party pumps exposed the beer to air so that it becomes oxidized within less than 24 hours
What gases must be present to ensure that draft beer is served properly?
CO2 or CO2 and nitrogen at the proper pressure setting
T/F: Compressed air is a proper substitution for CO2 and nitrogen in a draft system
False
What are the four key elements of a draft system?
- Keg
- Coupler
- FOB
- Faucet
What is the standard temperature of a draft system operation?
38 degrees F
Who should adjust gas and pressure settings for the draft system?
A draft trained professional
What are the five troubleshooting steps for draft systems?
- Ensure keg was cooled 24 hours
- Ensure coupler is secure
- Check FOB is functional
- No kinks in hoses
- Call professional
How often should draft systems be cleaned? Why?
Every 14 days to prevent off flavors
T/F: bottle, conditioned beers should be stored upright at 70°F
False: should be stored upright, so sediment settles, but should be stored at 43° or lower per brewer instruction
What is the proper technique for changing a keg?
- Pull handle to disengage coupling
- Turn counter clockwise 90°
- Apply coupling to new keg
- Turn new keg, 90° clockwise
- Lower handle to engage coupling
- Prime FOB detector
Storing beer away from light helps prevent which off flavor?
Skunk
What part of the draft system allows gas to flow in and out?
Coupler
What is the proper position of a coupler connected to a keg?
Clockwise to tread on keg with handle down
