Water massively impacts your coffee's flavours. But most of us struggle to fix our water because water science is confusing...

Join me and James as we go step-by-step through:

• Why these concepts matter for coffee flavour and equipment
• How to test your water at home
• How to fix it, depending on what you're working with

Check James' website for all of the visuals mentioned in the episode.

This episode developed thanks to Nick, who thought it would be a good time to revisit a bit of my history in coffee to reconnect with long-time listeners, and to share a bit more about myself with new listeners. We started this podcast about 6 years ago, and if you've been through all 72 episodes, you probably have a good idea about my coffee philosophies. 

But I also know that not everyone enjoys, or maybe even has the time to go back and start at the very beginning of a podcast. So we thought it would be a good opportunity to give you a bit of my coffee origin story, and a manifesto of sorts, all under one roof.

Today's episode offers a behind the scenes view of how I approach a coffee producer's first time using yeast for their coffee fermentations.

We run through all of the potential variables to pay attention to when designing your first trials with commercial microbes. From cost of production to work-flow and data collection.

Some of the questions in this episode:

• What typically happens to the water, along with cascara and whatever else is part of a fermentation, after the fermentation has been completed?
• Cascara is sometimes processed into a secondary product, cascara tea. Are there other secondary products that are made?
• As a roaster, what should we put on our bags to better point towards the farm?
• What's the consensus on adding flavor descriptors to bags? Do or don't?
• How can I store coffee cherry for 2–3 days without creating high damage?

I have wanted to make this episode for a long time, but I wasn't sure how to make it work. Finally some research for Dr. Flavio Borem helped crack the topic for me and the result is today's new episode.

 Things we discuss on this episode:

• Washed processed that tastes like a natural
• Process-forward coffees, funky coffee
• Neutral processing 
• The need for speed, & gentle drying
• Drying is not just removing water
• Biggest producer mistakes, not upgrading the drying
• Fallacy of terroir

I was going to create a new episode about Infused vs Inoculated Coffees, but much of what we established back in Episode #39 is still relevant. So I am pulling a Taylor Swift and going to re-release a new version of episode 39, keeping what still works and adding some new perspectives from the last 3 years.

In this episode I talk about:

• The sugar and acid additions that French and California winemakers use
• How adding mango to a fermentation tank is completely different from adding passion fruit or citrus
• How to tell when a coffee is infused with a flavor
• Cinnamon flavor in a coffee
• Inoculation vs Infusion vs Co-Fermentation
• The role of enzymes in removing mucilage
• Gravity!
