Difference between lager vs ale

Method of production
• Lagers: made using bottom-fermenting yeasts that require the fermenting liquid to remain at a cold temperature for a long time
• Ales: made using top-fermenting yeasts that work at warmer temperatures

This difference in production process affects characteristics such as flavour, carbonation and alcohol content. 

Taste and flavour
• Lagers: crisp, cooling, smooth and usually easier to drink
• Ales: sweeter, richer, more full-bodied

On top of the difference between lagers and ales, there is also some confusion when discussing lager and pilsners. Simply put, pilsners are a type of pale lager which have more spice and hop flavours.
