Talking Points

Recent interactions between the hosts and their guests.

Producer Toolkit: Fermentation, Pt 2 - The case for avoiding exciting fermentations
Q: Why can't you just add microbes and expect the same results everywhere?
Because the baseline conditions, farm context, and management practices determine outcomes; microbes are a tool that must be paired with good processes and environment to achieve consistent results.
Science: Water, Pt 1 - Alkalinity, hardness and why it matters
Q: How can we measure what's too much or too little alkalinity and hardness in water?
James promises a detailed walkthrough on measuring and treating tap water in the next episode.
Science: Water, Pt 1 - Alkalinity, hardness and why it matters
Q: How does water hardness affect coffee equipment?
Hard water produces limescale, which can build up in brewing equipment and make them inefficient, potentially causing expensive repairs.
Science: Water, Pt 1 - Alkalinity, hardness and why it matters
Q: What is alkalinity and why does it matter for coffee?
Alkalinity is how strong one solution is able to neutralize an acid, and it directly affects how acidic the coffee will taste.
Science: How specialty coffee woke up to water’s role in flavour
Q: What role does magnesium play in coffee water?
Magnesium is increasingly viewed as a crucial mineral that enhances the flavor of specialty coffees, although the exact mechanisms are still being studied.
