Beer is one of the world's oldest beverages. But for a long time, there was little that could be done to control the brewing process. With the advent of thermometry, however, brewing was standardized. Temperature control helped make beer taste even better. That's where we've seen the most innovation over the past two hundred years.
And as you can tell from the sheer volume of different beer on the shelves today, that innovation has continued at a rapid pace.
