The number of breweries facing problems with beer haze has been growing in the last days, even though two-stage filtration of beer is used. This problem is not usually cleared even when increasing kieselguhr or PVPP doses. It may be found interesting; that the results of the forced test have not changed the number of periods has not changed with it. The authors studied possible causes of this phenomenon and give tips what the brew producers can do in this situation.The number of breweries facing problems with beer haze has been growing in the last days, even though two-stage filtration of beer is used.

On the example of a forest ecosystem the importance of nature is illustrated not only for its marketable products and activities, but especially for its production of oxygen, sequestration of carbon, regulation of water cycle, aesthetic values, etc. These nature properties - services are by far not appreciated by mankind and there is no awareness of their economic value. According to one of the first serious analyses (Costanza et al., 1997) the economic value of the total ecosystem services freely supporting human societies has been estimated to be 33 trillion (1012) US dollars.(In Czech, English summary only)
