The beer, the liquid bread

The beer, the liquid bread

The beer is a liquid bread, that has no nutritional information.




The process of obtaining the beer is, at the beginning, similar to get the bread.
The ingredients are the same cereal, water and yeast.
The two products differ during processing, but the final results are very similar.
The analysis nutritional  of the bread is:  carbohydrates, fats and proteins,  in the beer is: carbohydrates, fat, protein and alcohol.
The substantial difference is that the bread is solid while the beer is liquid and contains ethanol.



The alcohol content makes the beer, a liquid bread, then is no longer considered a food, but an alcoholic beverage, and as such, the legislation does not impose a nutrition label, 
Nutritional labelling on alcoholic beverage packaging is voluntary in  most countries
Due to this lack, the consumer is not able to know what is drinking or rather how it is feeding.
In some countries also do not find the words "contains gluten ", and  we must remember also  that the yeasts, can cause intolerance. 
It 's almost impossible to know how many types of beer there are in the world, but  is certain, we don't find a beer like the other
The water, the method of preparation, hops, fermentation aromas make the beer a unique product.

When we drink a beer, we can introduce to a share of carbohydrates and also small part of protein and fat or introduce only alcohol ABV, depending the beer we consume.
This brief overview has been made of commercial beers, but what we know of the craft beers?

Most breweries don’t provide the nutrition data for their beers.
Using a few basic assumptions and information that many breweries do provide (like ABV and O.G.), we can achieve a relatively accurate calculation of this information.

We know the type of beer "Lager, Stout, Weiss, IPA ... etc, etc", the alcohol content ABV (some conversion degrees Plato) sometimes, the much discussed IBU ( International Bitterness Unit) which should indicate the bitterness of beer and a description made by bier sommeliers.
Beer is an anonymous food for informational nutrition, just an alcoholic beverage.



The consumer, until it will be indicated the nutritional values, will assume a quantity of bread or pure alcohol, and calories, without taking into account the specifics of carbohydrates, proteins and fats.
