Proper serving of draught beer is intended to have a “controlled” release of carbonation to give a better tasting and sensory experience. The evolution of CO2 gas during pouring builds the foam head and releases desirable flavors and aromas.
Technique

Proper Pouring Technique
- Hold glass at 45º angle, open faucet fully.
- Gradually tilt glass upright once beer has reached about the halfway point in the glass.
- Pour beer straight down into the glass, working the glass to form a one inch collar of foam (“head”). This is for visual appeal as well as carbonation release.
- Close faucet quickly to avoid wasteful overflow.
Pouring Hygene
- In no instance should a faucet nozzle touch the inside of the glass.
- Nozzles can potentially transfer germs from one glass to another.
- In no instance should the faucet nozzle become immersed in the consumer’s beer.
- Nozzles dipped in beer become a breeding ground for microorganisms.
- Importance of one-inch foam collar:
- While retailers struggle with customers who demand their beer “filled to the rim,” brewers prefer beer poured with about a one-inch collar of foam (“head”).
- A one-inch head maximizes retailer profit, as foam is 25% beer. Filling glass to the rim is really over-pouring.
- A proper head on a draught beer delivers the total sensory experience, including the following sensory benefits:
- Visual appeal of a good pour
- Aromatic volatiles in beer released
- Palate-cleansing effect of carbonation enhanced
- Textural and sensorial qualities of beer better presented to consumer
Free-Flow Pouring
- Beer pours best from a fully open faucet.
- To control the faucet during operation, hold the handle firmly at the base.
- Partially open faucets cause inefficiency and poor quality, namely:
- Turbulent flow
- Excessive foaming
- Waste (inefficiency)
