The Hop Industry
~100te hops grown per year, 75% in US and Germany
Four hop companies market ~ 80% of the world‘s crop with
market shares :
Barth Haas Group 35%
Steiner 25%
HVG 10%
Yakima Chief/HU 8-10%
The remaining 20%: small dealers, local cooperatives
World Hop Growing
The Hop Industry
Hops have an enormous flavor and aroma effect in beer but cost in use small. Hop quality is essential.
Brewing Trends in Last Decade
• Emergence of craft brewing – dynamic, innovative
• Increased popularity of intense hoppy beer styles
• Breeding of new flavor hop varieties (with high oil contents and intense hop character) also increased.
• Hop aroma and flavour character poorly characterized (cf alpha)
The Hop Market
Demand increasing:
Craft breweries USA, consumer taste
Supplies reduced:
Czech Republic and German Hallertau regions
weather crop failure, USA irrigation issues
Result:
2015 is a crop shortage year!!!

Is this a hop product?
Hop Aroma and Flavour
• Comes from the essential oils
• Composition of oil varies with hop variety
• 3 distinct groups- hydrocarbon (insoluble), oxygenated and sulphur containing.
• Affected by alcohol content, malt type and yeast – beer matrix
• IAA content changes aroma, taste and mouthfeel
Hop Oil Components

HopSensation
• Specific Blends of hop varietal oils combines late and dry hop character and hop fractions eg spicy:floral:cascade
• Emphasis is on balance and application to beer style
HopPlus
• Blends hop fractions with other botanicals (vanilla, chocolate, ginger, chilli) to give unique flavour profiles. Single additions, reproducible flavours.

• Can be pasteurised without loss of flavour
• Economics
• Supply
Cost in Use
• 100% hop utilization in the brewing process, when compared to ~ 33% hop utilization from hop pellets
• Cost in use will be less when compared to hop cones
• Additional benefits of capacity, throughput, lower beer loses
• Cost exercise:
• TNS Hop fractions vs. Hop Pellets/Hop Cones
