Beer colors, from light, pale yellow, bronze, brownish red, brownish black to dark black, can form a continuous spectrum, explains the craft beer manufacturer here. What makes people brew different colors of beer? So is it true, as they say, that the darker the beer, the more nutritious?

As the water quality varies from region to region, water sources in different places show different hardness due to the different minerals contained in them. We now know that a good source of water for brewing beer has a pH of about 5.3. But at that time, people were almost completely "water blind", unaware of the impact of water quality on brewing. Fortunately, it has been found in practice that a good beer can be made even in areas where the water is hard if part of the roasted malt is added to wort.

Because the malt after roasting is light brown to charcoal black, the result is a darker beer. Similarly, in other places where the water is softer, the malt cannot be roasted and needs to be used directly to make good beer. Modern science tells us that malt roasting produces an acid that lowers the pH of the water, and that the harder the water, the more black malt is needed, and the softer the water, the less black malt should be used. In this way, each region's beer takes on its own color, depending on how much malt is roasted and how much is used. It's all about the local water quality. Today water treatment is a very simple technology, so you can make beer of all colors anywhere in the world. Roasting malts can give beers different flavors and textures, as well as intriguing colors.

So is stout more nutritious? The difference between ale and ale is the roasting of malt. After the malt is roasted, some of the organic material is carbonized, forming coke and turning black. If coke is ever found to be nutritious, stout will be even more so.

One might ask, how many beers can a home-brewer make? In fact, brewing equipment mainly brewing yellow beer, dark beer, wheat beer, red beer, green beer and other products as auxiliary brewing. So the following article and you explain how to use the brewing equipment to brew dark beer knowledge.

Dark beer brewed by self-brewing equipment is one of the original beer, dark beer color is often more than 40EBC, the liquor is reddish brown, mellow wine, fine foam, moderate bitterness, has the reputation of "black milk", also suitable for drinking in cold seasons.

The first: material selection. Self-brewing beer equipment usually uses high solubility, relatively deep color, small grain quality malt, with about 10% of the black malt, sometimes use appropriate amount of amber malt, we also call him for sweet malt to increase the malt flavor of finished beer, and avoid excessive coke and coke bitter taste, affect the taste of beer. Black malt crushing degree can be appropriate coarse, in order to prevent filtering difficulties.

Second: add sugar color. The amount can be determined according to the chroma standard of the finished beer, generally not more than 0.2% of the liquor, can be added in the beer filter of the brewing beer equipment. Because the taste of beer largely depends on the quality of colorant, so in recent years, the use of maltose color, its basic composition is close to wort, and good solubility, is a better colorant, but can not be added too much.

Third: production. If you consider mass production of dark beer, you will need to equip a yeast saccharification fermentation equipment to ensure the stable quality of the dark beer brewed by the self-brewing equipment, and avoid interference with the production of other varieties of products.
