- This week I welcome back Dr Charlie Bamforth, Professor Emeritus at the University of California at Davis. Charlie specializes in the study of the wholesomeness of beer including beer perception, polyphenols, foam stability, oxidation and flavor stability.
- We start by discussing how Charlie got the name “The Pope of Foam”
- We have a brief discussion on carbonation levels, how they are measured and how they vary for different styles of beer.
- Charlie explains what the bubbles in beer foam are composed of and how their stability is important.
- We talk about nucleation and the size of bubbles in relation to their long term stability.
- Charlie explains the key ingredients in beer, specifically malt and hops and how they provide the building blocks for foam stability.
- We discuss the brewing process and how you can choose mash temperature to maximize foam.
- Finally we talk about glasses, glass shape and the very important process of serving beer.
- Charlie provides his closing thoughts.
