“A fine beer may be judged with only one sip, but it's better to be thoroughly sure.”
Beer 101
1. Power of 3
The term beer encompasses roughly 3 types of fermented beverages: Ale, Lager and least known, Lambic or Mixed Origin beers.
Ale
In short, Ales are a type of beer that ferment at warmer temperatures (60-75 F) and form a layer of foam on top, giving them the name of top-fermenting beers.
Lager
Lagers are a type of beer that ferment at temperatures averaging 50 F and contain a complex sugar, raffinose, as a byproduct of fermentation. Unlike ales, lagers ferment at the bottom, giving rise to the name bottom-fermenting beers.
Lambic
Lambics and mixed origin beers are sometimes bunched up together and forgotten, even though they are original beers that fueled the creation of a beer-brewing industry. Unlike ales and lagers where the yeast cultures used for fermentation are carefully selected, lambics and mixed origin beers are spontaneous-fermentation beers, meaning the yeasts that are involved in their fermentation are naturally occurring ones. Compared to ales and lagers, lambics cover the smallest portion of the beer market and are only manufactured in Belgium, more specifically in the region surrounding Brussels, where the yeasts that are native to the Senne (Zenne) valley are used.
2. By the looks of it...
There are three visual characteristics that are usually observed in a beer and they are colour, clarity, and nature of the head. Colour is usually imparted by the malts used, notably the adjunct malts added to darker beers, though other ingredients may contribute to the colour of some styles such as fruit beers.

3. Aroma, Flavor and Feel
Aroma
The aroma and flavour in a beer ares formed by a combination of the malts and other fermentables used, the strength and type of hops, the alcohol, esters, and various aromatic components formed by the yeast strain as well as other elements that may derive from the water and the brewing process. Bitterness can be measured on an International Bitterness Units scale, and in North America a number of brewers record the bitterness on this scale as IBUs.
The feel of a beer in the mouth, both from thickness of the liquid and from carbonation, may also be considered as part of a beer's style. A sweeter beer feels thicker in the mouth. The level of carbonation (or nitrogen, in "smooth" beers) varies from one beer style to another. For some beers it may give the beer a thick and creamy feel, while for others it contributes a prickly sensation.
