- Cito discusses what to look for in a hop – particularly to use US, New Zealand and Australian varieties that have higher thiol, linalool and geraniol.
- Chris tells us a bit about the additives like Phantasm that can increase the free thiol content in a finished beer by freeing thiols in the hops.
- Vito discusses the difference between thiol content and free thiols.
- Chris discusses certain yeasts that have been modified or bred to enhance the biotransformations that happen during fermentation to create the fruity compounds.
- Vito discusses these yeast and who has them.
