CONTAMINATION CAN INFILTRATE
FROM A NUMBER OF SOURCES
STARTING MATERIALS
Everything that comes into contact with the yeast must be sterilized. The wort leaving
the kettle has been through the boiling process and therefore should be relatively ster-
ile. But if the wort cooling system is not clean, contamination can be introduced before
it enters the fermentation vessel.
BREWING PLANT
Any surface that comes into contact with wort, beer, or yeast should be thoroughly
cleaned and sterilized (e.g. vessels, piping, and implements). Soiled surfaces can
support a microbiological growth that can be introduced into the beer. Any recurrent
contamination may indicate the presence of a biofilm. Biofilms are particularly difficult
to clean, as they can bind strongly to the vessel or pipe. Localization of the biofilm may
be necessary before adequate cleaning can be performed.

POOR SANITATION AFFECTS
THE QUALITY OF THE BEER
Most contaminants will produce off-flavors, acids and non-desirable aromas. They can also produce hazy beer and
films. They may compete with the production strain for essential nutrients; they can also induce stuck fermentation or
over-attenuated beers. There are two major groups of microorganisms responsible for contaminating wort and beer:
1) Wild Yeast and 2) Bacteria.
YEAST
WILD YEAST
"Any yeast that is not deliberately used and under full control."
• Contamination can occur if the pitching/cropping yeast is in con-
tact with air.
• Wild yeasts are not killed by acid washing and therefore produc-
tion yeast contaminated with wild yeast needs to be discarded to
avoid product defect.
BACTERIA
• Can grow rapidly in wort and beer. Fresh wort must be pitched
as soon as possible with active yeast to prevent bacterial growth.
• Bacteria can cause off-flavors and compete with yeast for essential
nutrients. BACTERIA
Acetic Acid Bacteria Produces vinegar (acetic acid) from ethanol Causes off-flavors
CLEANING AGENTS
Spartan Chemical offers two types of cleaning detergents: alkaline-based and acid-based. Our powerful cleaning agents are
formulated with surfactants, chelating agents, and emulsifiers to enhance the effectiveness of the products. Capable of pen-
etrating deep soil deposits, Spartan cleaners efficiently break the soil into fine particles and hold them in suspension so that
they do not redeposit on the cleaned surface. Calcium and magnesium salts (beerstone) are liberated and rinsed clean away.
ALKALINE-BASED DETERGENTS
• Effective in removing organic soils (i.e., oils, fats, proteins, starches, and carbohydrates) encountered in brewing.
• Will not remove calcium oxalate and other inorganic compounds that lead to a build-up of beerstone.
ACID-BASED DETERGENTS
• Commonly used in a two-step sequential cleaning regiment with alkaline detergents.
• Primarily used for the prevention or removal of beerstone, water scale (calcium and magnesium carbonates), and alu-
minum oxide.
• Will not work for heavy soils, tannins, hop oils, resins, and glucans.

THE SANITIZING PROCESS
Sanitizing reduces the surface population of viably microorganisms after cleaning and prevents microbial growth on the
brewery equipment.
SANITIZING AGENTS
Spartan offers a full line of sanitizers for each step of the brewing process. After surfaces have been completely cleaned and
rinsed, a sanitizer cycle will ensure that unwanted microorganisms are reduced to acceptable levels in brewing.
