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.​​

Throughout the world and throughout history, you can find evidence of cultures enjoying cold desserts—precursors to the ice cream we love today. The desire to keep food cold led to the creation of European wine slushies in 1558 and to the transportation of ice from New England to the Caribbean in 1806. 

Soon enough, advances in production, serving and shipping methods made ice cream popular and more readily available throughout the United States. Through Prohibition, war and beyond, enterprising people continued to innovate with new flavors, mix-ins and ice cream making machines. 

Now, a new generation of entrepreneurs are helping ensure there’s an ice cream for everyone to enjoy. Get the scoop on this episode of Trailblazers.
