13 BrauKon HopGun Benefits» Simple and user-friendly HopGun for dissolving hop pellets into finished beer» Defined and gentle solution of hop pellets (type 90 and 45)» Efficient extraction, which provides constant and defined flavoring» Hop is saved through efficient extraction» The HopGun can be flexible integrated in an existing cellar» Simple automatic system with low mechanical investment» Similar sensory results with less amount of hop, compared to convent. methods» Low turbidity and more biological stability through high effect of clarification

14 BrauKon HopGun Appendix Dry hopping trials in cooperation with the University of Weihenstephan

15 BrauKon HopGun dry hopping test I Describtion and Results of dry hopping test I HopGun in comparison with conventional dryhopping method Same test conditions for both set ups: o 1200 g Pellets (3 g/l, Saphir hops from same batch in 2013) o 4 hl (100 gallon) Beer, bottom-fermented, German lager style o beer temperature ~ 38 F

16 Beer analyses BrauKon HopGun dry hopping test I Linalool [ µg/l ] 1 day 7 days 7 days (aging simulation) 45% increasing of Linanool yield conventional method HopGun

17 BrauKon HopGun dry hopping test I Beer analyses Myrcen [ µg/l ] 1 day 7 days 7 days (aging simulation) 160% increasing of myrcen yield conventional method HopGun

18 BrauKon HopGun dry hopping test I Sensory results Tastings with trained tasting-experts of Univ. Weihenstephan (DLG tasting panel) Ranking order test (increasing order of intensity of hop aroma and flavor) basic Beer conv. method_7days HopGun _7days (9 of 10 taster) conv.method_1day conv. method_7days HopGun _1day (10 of 10 taster)

19 BrauKon HopGun dry hopping test I Sensory results Triangular test (identify the difference): (with 10 trained persons) identified conv. method_1day - conv. method_7days 50% (non signif.) HopGun _1day - HopGun _7days 30% (non signif.) conv.method_7days - HopGun _7days 100% (high signif.) conv.method_7days - HopGun _1day 90% (high signif.)

20 BrauKon HopGun dry hopping test II According to high yield of hop aroma with HopGun: Repeating of trials with reducing 50% of hop pellets for HopGun New conditions for dry hopping test II HopGun in comparison with conventional dryhopping Method 600 g Pellets (1,5 g/l) 1200 g Pellets (3 g/l) Other test conditions were identical for both set ups: o Saphir hops from same batch o 4 hl (100 gallon) Beer, bottom-fermented, german lager style o beer temperature ~ 38 F

HopGun _1day - HopGun _7days 20% (non signif.) Although reducing 50% of the amount of hop pellets in HopGun : o No significant difference in hop flavor for all sensory results o Already after one day full extraction of hop flavor with HopGun

27 Turbidity [EBC] BrauKon HopGun dry hopping test III 30 Turbidity after dry hopping % less turbidity basic beer (filtrated) conventional method HopGun High level of clarification with HopGun
