Beer and Craftbeer is any fermented beverage made with a cereal grain. Specifically, beer is made from these four primary ingredients:

​

• Grain (mostly malted barley but also other grains). You have a cereal grain to thank for that loopy feeling you get after drinking a few bottles. But before is necessary to get the facts on how barley acts as the food source for the yeast in your beer. The main grains used to brew a beer are the Barley and Wheat. but exist others like: rye, corn mixed with rice (normally used in industrial beer), oat, ...

​

       Wheat beers are brewed with a blend of wheat and barley where the wheat portion is anywhere from 30-70% of the total.

       Wheat extract malts are typically 40% wheat and 60% barley. Wheat has more proteins than barley and contributes to great

       long-lasting heads, but also gives more haze. Wheat is lighter in color and contributes less flavor than barley, so it

       makes for a great summer drink

​

      Which is the best Barley Suited for a Beer?. Barley is responsible for producing the sugars needed that the yeast turns into

      alcohol.  As stated above, it is a cereal grain that is grown worldwide in temperate climates. Contrary to how cereal grains are

      used in most food products, barley must be processed into malt (or malted barley)before can be used in beer. Malt is created

      through the natural process of malting, done by a professional maltster.  You malt barley by soaking it in water for a few days,

      allowing it to germinate and produce the components necessary for fermentation. This same process can be done with other

      grains such as wheat or rye, but barley is the most common in the beer world.

​

      What Malt does for your Beer? . Give malt a lot of credit because it adds much more than just alcohol to beer. Flavor, aroma,

      and body are all influenced by malt. Malt leaves traces that are generically summed up by an essence of sweetness. That is a

      generic statement however, because there are dozens of varieties of malt that contribute unique characteristics. There are

      even specific malts (aka base malts) that are specifically used for their fermentable sugars while other malts (aka specialty

      malts) whose sugars can’t be fermented and are only used for their flavor qualities. Malted barley is to beer what grapes are

      to wine. They give their sugars to the beer and leave unique imprint on it. Learn what malt was used in your beer and you’ll

      have a good idea of what to expect from it.

​

• Hops (grown in many different varieties). The brewer uses hops to add bitterness that balances out the sweetness contributed by the malt. Without them, you’d have something tasking like an gross sugary soda-beer. Besides adding bitterness, hops also give flavor and aroma. The time at which the hops are added determine how the beer tastes. Add them early and the beer will be more bitter. Add the hops later and it will be less bitter, but have more flavor and aroma.

​

       The hop and brewer's experience makes the craft beer completelly diferent to the others.: it is the magic and style of this

       beverage.

​

• Yeast (responsible for fermentation; based on style-specific strains). Oh the enviable life of a yeast cell. It eats all day to its hearts content, belches without judgment, and rests when it’s full. All the while being thanked by the brewer for the treasured byproduct of this process – alcohol. Yeast in it’s simplest terms converts the sugar in beer into CO2 and alcohol. Technically it is a fungus, invisible to the naked eye but nevertheless the magical ingredient that makes a beer a beer. Yeast also influences the final flavor, usually adding fruity and spicy notes. But its primary job is making booze.

​

• Water (accounts for up to 95 percent of beer’s content).Water gets very little respect as an ingredient in beer, yet it makes up over 90% of what is in your pint glass. Not so long ago, one of the major health benefits of beer was that it was boiled and deemed safe for drinking. At 90% by volume, it is obvious that the water used in brewing has a big influence on the finished product. In fact, many styles of beer are known for the water used.
