What is an altbier beer and what sets it apart from other beer styles?
An altbier is a type of German beer that is top-fermented and known for its balanced maltiness and hop bitterness. It is typically darker in color and has a clean, crisp finish. What sets it apart from other beer styles is its combination of ale and lager characteristics, as it is fermented at cooler temperatures like a lager but with ale yeast.
What kind of yeast is used in beer making?
They use Ale Yeast.Their are hundreds of varietys of strains.Ale yeast is top fermenting.Their is also bottom fermenting yeast which is Lager yeast.Top-fermenting yeasts are used for brewing ales, porters, stouts, Altbier, Kölsch, and wheat beers.ager styles made from bottom-fermenting yeasts are Pilsners, Dortmunders, Märzen, Bocks, and American malt liquors. There are many different "strains" of yeast used in beer making. There are also several companies in the business of culturing yeast for sale to the home brewer. Off the top of my head, White Labs and Wyeast are probably the ideal brands to look for, with Wyeast being the most user friendly. They have "smack packs" which come with a nutrient/starter in the pack and you can tell if it's good yeast when the pack expands.

Difference between bottom and top fermenting yeast?
Yeast are single-celled microorganisms that reproduce by budding. They are biologically classified as fungi and are responsible for converting fermentable sugars into alcohol and other byproducts. There are literally hundreds of varieties and strains of yeast. In the past, there were two types of beer yeast: ale yeast (the "top-fermenting" type, Saccharomyces cerevisiae) and lager yeast (the "bottom-fermenting" type, Saccharomyces uvarum, formerly known as Saccharomyces carlsbergensis). Today, as a result of recent reclassification of Saccharomyces species, both ale and lager yeast strains are considered to be members of S. cerevisiae.Top-Fermenting YeastAle yeast strains are best used at temperatures ranging from 10 to 25°C, though some strains will not actively ferment below 12°C (33). Ale yeasts are generally regarded as top-fermenting yeasts since they rise to the surface during fermentation, creating a very thick, rich yeast head. That is why the term "top-fermenting" is associated with ale yeasts. Fermentation by ale yeasts at these relatively warmer temperatures produces a beer high in esters, which many regard as a distinctive character of ale beers.Top-fermenting yeasts are used for brewing ales, porters, stouts, Altbier, Kölsch, and wheat beers.Bottom-Fermenting YeastLager yeast strains are best used at temperatures ranging from 7 to 15°C. At these temperatures, lager yeasts grow less rapidly than ale yeasts, and with less surface foam they tend to settle out to the bottom of the fermenter as fermentation nears completion. This is why they are often referred to as "bottom" yeasts. The final flavour of the beer will depend a great deal on the strain of lager yeast and the temperatures at which it was fermented.Some of the lager styles made from bottom-fermenting yeasts are Pilsners, Dortmunders, Märzen, Bocks, and American malt liquors.
