Hopus is a beer that has everything to do with hops. Many breweries attempt to offer a varied range of beer styles, and it is common nowadays to include highly hopped beers in that range. In fact, already being 77 beers in to the journey, it is fairly surprising we haven’t really spoken about hops as yet, as they have been integral to the beer making industry for over 700 years.
Their primary uses in brewing are that of a flavouring agent, and an antibiotic against less desirable micro-organisms than the specific type of yeast selected, and it is probably worth dealing with the science before going any further. Hops are most often dried before use in an oast house or similar facility, which goes to work on the resins within the plant. These resins contain two types of very useful acids – alpha and beta. The alpha acids contain a mild antibiotic effect against harmful bacteria and as already mentioned help to propagate the yeast used. These acids tend to also give the beer its bitter flavour. The beta acids do not tend to add to the flavour of the beer, but through their addition to the wort can give the beer wonderful aromas. The brewers choice of end product will largely determine exactly what type of hops to use in the brewing. The former are generally known as ‘bittering’ hops while the latter are known as ‘aroma hops’.
This degree of bitterness imparted from the hops depends on the extent to which alpha acids are isomerized during boiling, and they tend to be measured in International Bitterness Units (IBUs)*. Many European hop varieties tend to be ‘aroma’ hops, whereas the newer American types, are often ‘bittering’ hops. Bittering hops tend to be used for about 60-90 minutes of the brewing process, whereas aroma hops are often only used at the very end of the process. This normally occurs within the last five to ten minutes of the boil. Often, and this is very evident in Orval (#37), the hops are added after fermentation cold to the wort, which gives a very sharp hop flavour, and is usually known as ‘dry-hopping’.
There is plenty more to discuss on hops, but I shall go into that as and when the opportunity arises. This leaves me time to discuss the Hopus. Another beer poured from the rare swing-top bottle and one that exploded into the glass with a wholesome russet colour and a majestic head. The Hopus was certainly a sipper, which in fact lasted a whole episode of Match of the Day 2, and the flavour stayed true to the end. Nothing special, but certainly worth the trouble.
