  9. The Future

  10. Research at Davis

  11. Silicon • Silicon occurs in beer primarily through the hydrolysis silicate Si(OH)4 Si(OH)3O- + H+ • Previous research states that silicon is primarily added in this way from malt and from the mineral content of water

  12. Silicon and Bones • Si, in the form of soluble silicate, has been shown to increase the bone mineral density of men and pre-menopausal women • Due to silicon’s interaction with extracellular glycoprotein synthesis

  13. Aluminum • Al can be absorbed from sources such as drinking water and deodorant • Average Al intake of 2-5 mg per day, but as much as 20 mg per day • Silicic acid has been shown to react with Al, probably by the formation of alumino-silicates, to reduce the levels of Al

  14. Research Design • Commercial Beer • Malting Process • Raw Materials • Grain, hops, water, yeast • Process Aids • Silica gel, Diatomaceous Earth • Brewing Process

  15. Commercial Beer

  16. Raw Materials - Malt

  17. Raw Materials - Hops

  18. Process Aids • Diatomacious Earth - No silicon pick-up • Silica Gel - No silicon pick-up

  19. Mashing/Lautering • 4 tests - Same malt, 65ºC conversion temperature • 60 min mash in mash tun, gentle lautering • 45 min mash, transferred to lauter tun, gentle lautering • Two 100 min mashes, transferred to lauter tun • One gentle, one “vigorous”

  20. Mashing/Lautering

  21. Boiling • Two 1.3 bbl brews (10 °Plato, 15 IBUs) • 60.4 grams hops added (284 mg Si) • 20 minute whirlpool with Irish moss added

  22. Fermentation • Two 1.3 bbl brews (10 °Plato, 15 IBUs) • Ale yeast pitched at 10*106 cells/ml Brew 1 Brew 2 49.3 mg Si 67.2 mg Si Yeast Slurry Yeast Slurry 1808 mg Si 1362.54 mg Si (73.4%) 1893 mg Si 1749 mg Si (89.2%) Boil Fermentation Boil Fermentation Spent Yeast Spent Yeast 48 mg Si (2.6%) 32.2 mg Si (1.6%)

  23. Brewing at 5707’

  24. Established to create specialty beers for discriminating beer drinkers Specializing in small batch brewing Uniquely located at 39º 45' 36" N by 105º 12' 51" W Brewed at an altitude of 5,707 feet above sea level Small, 30-barrel Huppmann copper kettles, imported from Germany in 1973. Brewed by brewers, not computers

  25. IntroducingHerman Joseph’s Private Reserve

  26. Herman Joseph’s Private Reserve is a German-style lager brewed by AC Golden Brewing Company and sold only in Colorado. Born of German heritage dating back to 1868, Herman Joseph’s recipe combines the finest European and North American hops with our prized Moravian two-row barley. Each small, 30-barrel brew begins with a slow and easy 120-minute boil. Select ingredients are added at the precise moment to build its taste complexities. Each brew is then chilled to 1º Celsius and allowed to rest for weeks on end. This Chill-lagering develops each HJ Private Reserve brew into a perfectly balanced, deep golden lager that is appreciated for its distinctive qualities and unmistakable crisp, clean finish. Every bottle bears its distinct brew number and each case is hand packed and sealed, assuring you that the Herman Joseph’s Private Reserve inside meets our uncompromising standards. Because of the extra time required to brew, age and package this rare beer, it take us longer to craft Herman Joseph’s Private Reserve – we believe you will agree……..it’s worth the wait.

  27. Ingredients • Four Hops • German Hallertauer Taurus • German Hallertauer Perle • North American Sterling • Saaz Noble Hops • Four Malts • Moravian two-row • Weyermann CaraHell • Dingemann's Cara 8 • Briess Black Malt

  28. Special Features • Private Reserve • Extremely limited production • Average of 90 cases per week • Long brewing and aging requirements • Hand made by brewers, not computers • Hand packed, inspected and sealed • Recipe roots extend back to 1868 • Extremely limited distribution • Available in select upscale Denver area restaurants • Sold only in Colorado – Great suggestion for out-of-town guests • Every brew is identified with a “Brew Number”
