AbstractThis quarter the
TQ has two articles on hops and three on water. The first article is from a Canadian hop grower, and he raises several points that small brewers should be aware of; I was quite pleased to receive his enquiry on the subject. The second expands on the work of the novel wort separation system developed at Ziemann Holvrieka Corporation, investigating improvement of hop utilization by working with the different wort fractions. I contributed a short piece describing my philosophy on water adjustment for mash pH and beer flavor. The article seeks to demystify the priorities of water adjustment by describing how beer style parameters best relate to water parameters, and it shares simple calculations for adjustment. This issue also shares two hypothetical case studies that were conducted in the Master Brewers Short Courses; the same question was posed in two different courses, and the priorities of the different courses might affect the responses. The case studies should be of great interest to many of you, because they deal with a common issue for many breweries—water usage and money. The case study asked the question of how to reduce water consumption throughout the brewing process at each stage of production, and more importantly, how to measure the physical and financial impact. This question was asked of one group in both the Brewery Engineering and Utilities course and the Brewing and Malting Science course. The results are useful for every operation to consider.
