Agenda
• Trip around the world in recognition of Seattle's flying history
• Review of Malting• Malting as it relates to Brewing• Barley around the world

Barley as it Relates to Malting
• Barley is the soul of Beer• All kernels must grow: free of sprout or
chitted kernels• All kernels must grow evenly: S&B or
Skinned• Correct protein levels• Free of mold, vermin etc.

Barley Malt Contributions to Brewing
• Source of Carbohydrates• Source of Protein• Source of enzymes to reduce
carbohydrates to fermentable sugar• Source of enzymes to reduce proteins• Source of filter material for “Wort”
clarification• Source of Color and Flavor

Carbohydrates
• Most abundant organic compound in nature• All are built as chains from Glucose –
C6H12O6
• All are built by plant photosynthesis• Common forms we recognize are sugar,
starch and cellulose

Proteins
• Basic raw material in tissue and cell building• All are built as chains from 20-25 different
amino acids• Amino acids are built from nitrogen, carbon,
hydrogen, oxygen and sometimes sulfur• All are built by plant photosynthesis
![Page 10: Malting Barley and the World · 2020. 7. 13. · 3 Barley as it Relates to Malting • Barley is the soul of Beer • All kernels must grow: free of sprout or chitted kernels •](https://reader035.fdocuments.in/reader035/viewer/2022081622/6135685bdfd10f4dd73c5a78/html5/thumbnails/10.jpg)

Enzymes
• The “Worker” proteins• Catalysts that regulate the speed of chemical
reactions without being involved in or consumed by the reaction
• Function by reducing carbohydrate and protein chains by breaking bonds between glucose units and amino acid units

Barley Benefits
• Source of filter material for “Wort” clarification– Other grains can be malted– Barley malt is the best package for Brewing
• Source of color and flavor– 100% of Beer Color comes from barley malt– Significant amount of beer flavor derived from
barley malt

Malting Process
• Agricultural product in: Barley• Food product out: Malt
– All FDA processing/sanitary requirements in place• Production cycle 8-10 days• Malt is aged 21 days minimum before shipment• Ship to brewery
– Mostly railcars

• The major issues limiting China’s ability to grow its domestic malt barley supply are:– Low and inconsistent grain quality…variety
and growing practices– Post harvest quality deterioration…handling
and storage– High logistical costs and infrastructure
constraints…growing region specific– An underdeveloped quality control system
