In the Hop Aroma Compendium you will find a detailed description of unique aromas of 48 hop varieties out of the United States, Australia and Germany. No other raw material used in brewing has such a great influence on the aroma, flavour and bitterness of the beer as hops. And no other raw material has as many aromas as hops. In the last few years, there has been a growth in the number of brewers who wish to rediscover hops in order better to differentiate their beers. They want to know not only the alpha or oil content; they are interested not only in technical values. What they want to know is how the hops smell, what aromas they have and what effect these aromas may have on the finished beer. Joh. Barth & Sohn, the leading provider of hop-related services, has therefore cooperated closely with two world champion beer sommeliers and a perfumist to itemise and describe in detail the aromas of the most important hop varieties. Each hop variety has its very own aroma composition and each hop variety changes a beer’s flavour. The original hop aroma is, of course, only a starting point, but those who know the hop aromas and their effects can also arouse enthusiasm among their customers for nuanced beers. Discover hops and their incomparable aromas in the interests of beer and of your customers!
