Beer is primarily made of a few core ingredients that includes water, grain, hops and yeast. Occasionally other additives are used to adjust the beer’s flavor including things like fruit, sugar and spices.
Beer Maverick has compiled the web’s largest online searchable database for hops, grains and yeast for use in beer making. We’ve scoured the internet, publications and research papers to get you the most complete information in order to brew great beer.
Fermentables such as grains, extracts and various sugars are mashed in approximately 144-170° F water, which creates the wort that ultimately turns into beer with the help of both yeast and hops.
There are two main categories of grains: base and adjunct. Beer recipes consist of a high percentage of base grains such as 2-row barley. Adjuncts are then added to the recipe to add color, flavor and viscosity to the finished beer.
Sometimes grains can be pre-boiled by the grain manufacturers, which then sell the resulting product as an extract. Extracts can be sold as either a liquid syrup (LME) or as a dry powder (DME).
Hops are used to impart bitterness and aromatic flavors to beer, however certain compounds also possess antimicrobial properties. The iso-alpha-acids in particular possess strong antibacterial action against certain strands of bacteria.
In historical times, “gruit” or other vegetation were used to add bitterness to beer, but were quickly replaced by hops as it was found that hops simply did a better job at keeping the beer stable and safer over longer periods of time.
Hops are classified as Bittering-, Aroma- and Dual-purpose varietals, each corresponding to their typical use cases in brewing beer. In general, bittering hops are added early in the boil, aroma hops are added late in the boil and as a dry hop. Dual-purpose hops can be used at any stage of the beer production process.
Yeast eats the sugars in the water the grains were mashed in and boiled – called wort – and transforms them into alcohol, CO2 and various flavors and aromas called esters. Yeast are very picky as to the type of environment they best work in. They love to have plenty of nutrients, just the right temperature and if they don’t – they get stressed and create off-flavors or simply don’t work.
There are over 100 different strains of beer yeast, and each create their own unique set of flavors, haze levels and alcohol content. Because of these differing qualities, choosing the right type of yeast for your beer style is essential.
