It's a beer world after all!
While your favorite brew might contain additional ingredients, beer is generally made out of grains, spices, yeast,
and water. Although sugar is not included in the list, it’s necessary to produce alcohol. As such, you may wonder
whether there’s any sugar in beer and how much it contains.T o know how much sugar is in beer, you first have
to understand how beer is made The main ingredients in beer are grains, spices, yeast, and water. Barley and
wheat are the most utilized grains, while hops serve as the principal flavoring spice The brewing process
consists of the following steps
 1. Malting. This step allows for the controlled germination of the grain. This is
a key step, as germination helps break down stored starch into fermentable sugar — mainly maltose.
2. Mashing. Mashing is the process of roasting, milling, and soaking the germinated grains in hot water. The result
is a sugar-containing liquid called wort. 3.
Boiling. During this step, hops or other spices are added.
The wort is then briefly cooled and filtrated to eliminate plant residue and debris. .4.
Fermentation. At this point,
yeast is added to the wort to ferment it, which converts sugars into alcohol and carbon dioxide. 5.
Maturation. This
is the last brewing step, during which beer is stored and left to age.

As you can see, sugar is an essential element in beer making.However, it’s not added as an ingredient. Instead,
it comes from the processing of the grains and is then fermented by yeast to produce alcohol
.
===================================

Beer gravity refers to the density of the wort relative to water at various stages of fermentation, and it’s mostly
determined by sugar content. A wort that has a high sugar concentration is called a high gravity wort.
As the yeast ferments the wort, its sugar content decreases while its alcohol content increases, which in turn
lowers its gravity and results in a beer with a high alcohol content.

Therefore, beers have an initial and final gravity, and the difference between the two indicates the amount of
sugar that was converted into alcohol. Both ales and lagers are different types of beers, and their main
difference is the yeast strain used for brewing.

Ale beers are made with the Saccharomyces cerevisiae strains, while lager beers use Saccharomyces
pastorianus (3Trusted Source). Beer yeasts are highly efficient when it comes to fermenting sugar.
Still, several factors affect yeast’s fermenting efficiency, including brewing temperatures and beer’s rising
alcohol content. Once the alcohol content is too high for them to survive, fermentation stops  While both strains
produce alcohol as an end product, ale yeasts have a higher alcohol tolerance than lager yeasts — meaning
that they can survive in higher alcohol environments Therefore, ales generally have a higher alcohol content and
lower sugar content. Sugars are carbs. In fact, sugar is the most basic unit of carbs.

Jack O'Reilly attended the
famous Siebel Institute/ World
Brewing Academy in Chicago.
I'm very excited to be part of the BeerNexus team.  I think my many years in the
beer business both as a brewer and manger will enable me to explain and
investigate many topics of interest for those who really love craft beer.
Hope you join me every month.  
Cheers
