Hops For Home Brew Beer Determines Bitterness And Flavour

ARTLEYSHOMEBREW.COM
Hops for home brew beer add flavour and bitterness as well as have a preservative action. Use of brewing hops can be traced back hundreds of years to Southern Germany where it was used to increase longevity of the brew. The practice was associated with the addition of other wild herbs for flavour and wild beer hops are still used. The hop oils and resins acted as a natural steriliser or disinfectant against the presence of wild yeasts that could spoil the brew before the days of refrigeration and airtight sealing.
Hops for Bitterness
For your home made beer brewing, the main purpose of adding hops is to give bitterness to what would be a sweet liquid, as is beer wine without hops to balance the flavours. If you want to experiment and use herbs for flavour you could try a beer without hops recipe.

Climate for Growing Hops
Hops are best grown in cool temperate climates and the vines are related to the mulberry, elm and the nettle. There are beer hops farms in USA, Australia, Europe and other countries with similar climates. Flowers are produced only on female vines and come out in a cone shaped bunch and are bright green. When crushed and dried they give off a pungent aroma that is refreshing and thus we get hops for beer.
 Chemistry
As with malts, the chemistry can be interesting for the home brewer as the active ingredients are tannins, oils and resins; and each component has importance to your home brew. If you’re not into chemistry, don’t worry; just be happy to know that something happens when hops are added to your brew.
The resins are the ingredients that supply the bitterness to your home brew beer. One of the resins is called ‘humulone’ and has the technical name of ‘Alpha Acid’ (AA) and the other resin of consequence is called ‘lupulone’ or ‘beta acid’. The bitterness of the hops comes from the more powerful humulones and this level of bitterness which varies with hop varieties is given an AA (Alpha Acid) rating. Thus, a strongly bitter hop has a rating of 7 to 11 AA compared with a milder hop of rating 3 to 5 AA.
Aroma
As well as bitterness, the other desirable factors are ‘aroma’ and flavour. For the home made beer brewing enthusiast, a balance of different hop varieties is essential to perfect your own favourite malty hoppy drop. Strong beers relying on malt for strength could have a high sweetness because of unfermented sugars from the malt and thus will require a strong bittering hops as well as aromatic hops to round off the overall brew.
Extraction
Extracting the bittering resins and active ingredients is achieved by boiling the hop flowers in water. The longer you boil the wort, the more bittering power you extract; and the more aroma and flavour you lose. Like extracting malt from grain, you need to be careful with temperature. So, boil the bittering hops for, say, one hour and then just as the boil is being stopped, add some aromatic hops so the excessive heat won’t kill the volatile oil aromas. One technique is to hold the hops in a suitable container and run the boiled wort through. Subtle? Yes! But when you hold up that sparkling pilsener glass of effervescent amber liquid and you say to yourself: “This is my own malty hoppy drop”, it will all be worth it.
Infuser Bag
On the other hand, in these days of top quality beer can kits to make home brew beer, all the malt extraction and hops blending have already been done for you by expert brewers. So, to experiment with extra hops, you can get the hops varieties in a little ‘teapot bag’ and include it in the cooled wort as the yeast is pitched and let the flavours infuse for the period of fermentation. So easy! So good!
