Fall is in the air. Are you ready for some Winter Beers?



The Basics

There are two basic yeast styles Ale and Lager They can be either liquid or dry. Ale yeast is a top fermenting yeast and is pretty forgiving. Lagers are bottom fermenting and a little more tricky. Yeast can have many characteristics and many variables will change the flavor.  The biggest the home brewer can control is temperature. As a beginner start with ales. 

Normal ale fermentation temperatures range from 68 to 72 °F (20 to 22 °C) and lager fermentation temperatures from 45 to 55 °F (7 to 13 °C). Also keep in mind that the heat generated by an active fermentation can warm a typical 5-gallon (19-L) batch of beer by 10 to 15 degrees Fahrenheit (5.5 to 8.3 degrees Celsius) 

High temperatures encourage the production of fusel alcohols - heavier alcohols that can have harsh solvent-like flavors. ... Excessively banana-tasting beers are one example of high esters due to high temperature fermentation. High temperatures can also lead to excessive levels of diacetyl more on that in the advanced area.
