\nRamada Grand Dakota Lodge, Dickinson, ND<\/p>\n
Alberto Jimenez-Diaz & Karen Hertzgard, assisted by Jerry Ford and Jon Stika gave a presentation on barley quality, malt production, wort production and making malt at home.<\/p>\n
In the malting of barley, more protein slows water uptake and germination.\u00a0 6-row barley contains more amylase enzymes, while 2-row barley has a greater starch content.\u00a0 Starch must first hydrolyze (absorb water) prior to enzymes conversion of starch to sugars.\u00a0 Higher protein content in barley slows the malting process and may result in lower modification as protein restricts the hydrolization of the protein- starch matrix.\u00a0 Unmodified barely is still \u201csteely\u201d and does not crush well into a proper grist.<\/p>\n
Green malt that is roasted while still wet or pale malt \u201cstewed\u201d then dried and roasted are two approaches to making crystal malt.<\/p>\n
Two-days of germination results in undermodified malt as starch is not granulized and little enzyme is produced.\u00a0 Four-days of germination is optimum for most malt barley varieties to achieve full modification with maximum enzymes present without sugar lost to seedling respiration.\u00a0 Seven-days of germination results in overmodified malt where some enzymes have been consumed to convert starch to sugar that is then respired by the growing seedling.\u00a0 The last stage of kilning malt determines type of malt produced: Pale, Munich, Chocolate, etc.<\/p>\n
Karen Hertsgaard Karen.Hertsgaard@ndsu.edu<\/a> invited members of the Heart River Home Brewers to tour the Institute of Barley and Malt Sciences http:\/\/www.ag.ndsu.edu\/ibms\/<\/a>\u00a0 in Fargo.<\/p>\n Paul Sadosky, Quality Assurance\/Quality Control of Summit Brewing Co., St. Paul, MN gave a brief presentation on the brewing process showing slides of the equipment at Summit Brewing.\u00a0 He mentioned that a Moravian variety of two-row barley was being grown in North Dakota and malted by Rahr Malt for use in the Summit Pilsener.\u00a0 Paul also mentioned that most American lagers are brewed with 48 pounds of malt to produce a 32 gallon barrel of beer.<\/p>\n Jerome Distributing of Dickinson provided samples of Summit Extra Pale Ale, Pilsener and Great Northern Porter.\u00a0 Jon and Jerry were able to visit with Paul Sadosky psadosky@summitbrewing.com<\/a> of Summit Brewing Co., Ray Albrecht Raymond_albrecht@cargill.com<\/a> of Cargill Malt, Spiritwood, ND and Daryl Miller of Rahr Malt, Taft, ND.\u00a0 All three invited members of the Heart River Home Brewers to tour their respective facilities if in the area.<\/p>\n","protected":false},"excerpt":{"rendered":" The Best of the Best in Wheat and Barley Research Tuesday, February 7, 2012 Ramada Grand Dakota Lodge, Dickinson, ND Alberto Jimenez-Diaz & Karen Hertzgard, assisted by Jerry Ford and Jon Stika gave a presentation on barley quality, malt production, wort production and making malt at home.
