A lager is a type of beer that comes in an array of flavors and styles, making it one of the most popular styles of beer in the world.
What is a Lager?
A lager is a type of beer that is aged, or ‘conditioned’, at low temperatures. Like other types of beer, it is made from fermented grain, but aging at low temperatures allows the yeast to survive longer, which brings out more flavors. This beer style can be both light and dark in color and is best when drunk cold. It usually has 3-6% ABV, although some styles are brewed to be stronger. One of the most calorie-packed alcoholic beverages, a pint of this beer can contain up to 240 calories.
Types of Lager Beer
There are many different types of lager beer, these include pale, Vienna, amber, and specialty lager. They make for amazing refreshment on a summer’s day and are best served chilled. 
- Pale: Pale in both name and nature, this type is lightly grassy, a little sweet and watery.
- Vienna: This is an Austrian variety that is amber in color and has a malty flavor.
- Dark: Very rich and malty, these types are dark in color and tend to have a high ABV. 
- Amber: These provide a good middle ground between the dark and pale varieties; amber lagers are medium-bodied, tend to have roasted caramel and interesting malt flavors, and can vary in levels of bitterness.
- Specialty: For the curious beer drinkers, there is a fantastic range of specialty lagers, stretching from smoked to sour.

Lager is made with hops, which contain a range of vitamins, such as B6, C, and E. Yeast, used in beer, can also be a source of potassium and dietary fiber and, when consumed in small quantities, alcohol is believed to be a good source of anti-oxidants. 
Alcohol Content (ABV): On average, 12 ounces of lager beer, or one bottle contains 5% ABV. However, it is advisable to keep an eye on the labels as certain brands of beer may have a much higher alcohol content than the average 4 percent to 6 percent. 
Risks & Side Effects
Moderation in alcohol consumption is key. The risks involved with drinking excessive alcohol can be short term such as violence and injuries to long-term health risks such as chronic diseases.
