THE
BREWING
INDUSTRY
Draft Lines – Where did we go
wrong?
SUPPORTING
THE
BREWING
INDUSTRY
Indicators of problems
• Off Flavours / odors
• Beer “surging” at the taps
– Excessive foam
– Repeat fills and pours to get a single pint
• Cloudiness / Haze
• Poor head retention
• Discolored draft lines
• Evidence of overall poor hygiene in the keg room or
tap area
If one or more of the previous
exist, draft lines/taps may be
contaminated
• Cleaning is a combination of 4
synergistic factors
• Each one must be employed
in correct proportion to get
desired results
• How many of these are
achievable and repeatable in
cleaning keg lines and taps?
• NONE
• Well….maybe some.
What are the challenges?
Chemistry used
Temperature
Time
Mechanical
Action
• Employ the factors we CAN
control in greater proportion
• Take advantage of time
• Use the correct cleaning
chemistry
How to overcome these
limitations?

What dictates the chemistry?
• Nature of the soil
– Mostly proteins
– Potential biofilm
– Limited mineral or beerstone
• Have to use the right chemistry that makes up for
lack of proper cleaning parameters
Chlorinated Alkaline Program
Chlorinated Alkaline Characteristics
• Alkalinity from Sodium or Potassium Hydroxide,
Sodium Carbonate, TSP
– Hydroxides are stronger
– Carbonate and TSP are milder
• Chlorine vastly improves the protein removal ability
of the alkaline ingredients
• Corrosion inhibitor a bonus but not absolutely
necessary
Deploy in the proper steps -
Basic Process
1. Flush lines with warm water
2. Prepare your alkaline cleaning solution in hottest
water possible.
3. Flush lines to taps and allow minimum 5 minute
soak
4. Rinse thoroughly with cold water
5. Flush with sacrificial beer to neutralize residual
Ideal Frequency – Monthly
Deploy in the proper steps
Advanced Process
1. Flush lines with warm water
2. Prepare your alkaline cleaning solution in hottest
water possible.
3. Flush lines to taps and allow minimum 5 minute
soak
4. Rinse thoroughly with cold water
5. Sanitize with POA solution at correct concentration
Twice per year – Clean with Acid
Solution
• Can use phosphoric acid only or phos/nitric blend
• Same process as the alkaline wash
Keg Coupler and Beer Taps need
love too
1. Soak the entire keg connector in detergent
solution
2. Disassemble taps and soak in detergent solution
3. Clean all parts with soft bristle brushes
4. Inspect all o-rings and gaskets for deterioration
(classic source of contamination)
5. Flush drain lines with warm detergent solution
6. Rinse all parts thoroughly and reassemble.
Challenge for Craft Brewers
• How to get the bar owners to follow these
recommendations?
• Greatest incentive – retain customers
• It is in their best interest
• Present a unified message – the need for clean
lines and taps should be consistently reinforced
• Merge interests to get the job done?
• Sideline business for someone’s
niece/nephew/grandmother/etc?
Thank You!
