Making Coffee with Lucia Solis

Where does sweetness come from? Can something taste sweet that has no sugar? How can we measure sugar in coffee? This will be a more technical episode where we will talk about the sugar compounds like carbohydrates, sucrose, glucose and fructose and sweetness as a concept. We will also look at how sugar content differs based on processing style: washed, honey or natural. Support the show on Patreo...

Today you get to be a fly on the wall of a consulting session between myself and a coffee producer in Uganda. The Coffee Gardens is a newer project of coffee producers who have partnered with select coffee farmers in Eastern Uganda. They currently work directly with 300 small holder farmers. They have a micro-processing station in the foothills of Mount Elgon. This episode might be most relevant t...

If you started the season with me in October you’ll remember that I started exploring the topic of what we lose when we take a plant from its native environment. Episode #25: A California Coffee Farm & Native vs. Local Yeasts looked at the relationship between coffee trees and the fermentation. Dr. Aimee Dudley’s research showed that the native microbes do not travel with the plant material an...

 We usually hear about coffee from roasters or even people like me, who work with coffee producers but we are not producers ourselves. One of my podcast goals is to bring you directly to the source. Whether it's scientific research or hearing directly from coffee producers. Often we leave it to coffee professionals and educators to speak about coffee producers but it’s rare to hear directly f...

What is left behind when coffee moves to new locations. What is the trade off for innovation?  This episode looks at what else we potentially leave behind when we introduce new plant material to non-native locations. The inspiration for this episode was a beautiful book by Peter Wohlleben called The Hidden Life of Trees. In it, Peter talks about native forests vs planted forests and the difference...

This week I want to talk to you about where native coffee yeast come from.  If you are concerned about coffee flavor manipulation by yeast, I hope by the end of the episode you have a broader understanding of where "native" yeast originally came from. To help illustrate the point, we start with non traditional coffee growing regions like Southern California. In the episode I will also be...

Aurora is back for another tea chat. Unfortunately I think coffee and tea are often lumped together in similar categories but they have very different histories and I think it’s worth trying to de-couple these beverages. Join us as we discuss how: -tea is largely consumed in it's botanical origins and coffee is not. -the different flavors of stress (positive and negative) -over extraction and...

What happens when the best in the world can't tell if a wine comes from the Willamette Valley in Oregon or Burgundy, France? What happens when the experts can't tell if the bubbles are from Champagne or California. Does a place really have a taste? Can we find it in the glass? That is the premise of terroir, tasting the land, localizing the product. But often, when put "terroir&quot...

Welcome to the next installment of terroir in coffee. This one little word contains a whole world of history and has an important role in the economic viability of certain agricultural products. After the last episode I heard from some of you who wished I had talked about soil minerals and plant nutrition from soil. Others also asked about the wine making regions like Bordeaux where Terroir is reg...

I'm so excited for you to join me in this discussion about terroir. Terroir comes from latin, for terra - soil. Also translated as land, or “taste of the land”. Terroir is predominantly a wine concept, so why are we even talking about it in reference to coffee? If you’ve listened to other episodes, you’ll know that there are certain concepts that the coffee industry likes to borrow from the w...

Have you ever wondered what would happen if you introduced foreign yeast and bacteria into a coffee farm? Or maybe you're curious if we can speed up a long fermentation by warming it up. How does post harvest processing affect the density of the seed? In today's podcast episode I’m answering listener questions like these and also sharing how I approach designing a fermentation. When I wa...

For those who know, it may not come as a surprise when I share how much I love tea. But professionally, today is the day I come out of the tea closet. I drink logarithmic levels of tea compared to coffee, and the more I confess that, the more other coffee professionals share with me that they too love specialty teas. Unfortunately I think coffee and tea are often lumped together in similar categor...

In today's Making Coffee Podcast episode, we're taking a deep dive into anaerobic fermentation and how language reflects values. Specialty coffee is a young industry. In the consumer space we have only recently started to differentiate between processing styles like natural, washed and honey and now we’re jumping off the deep end into the microbiology of these processing styles.  I wante...

Today's Making Coffee Podcast episode is a continuation of the theme of coffee pickers and their role in quality. In the previous episode I shared my surprisingly difficult experience trying to source red ripe coffee cherry. It was surprisingly difficult to pay the farmers more for a different quality than they were used to picking because of the established system, a system that developed ov...

Today's episode is part 1 of a 2 part series talking about the people who pick our coffee. In episode 15 we went deeply into how a molecule of sucrose in the coffee cherry pulp becomes a flavor compound like banana or peach and gets into the coffee seed. Flavor is an accessible entry point for specialness. However, I don’t like talking about flavor and coffee too much.  I don’t think coffee f...

Today's episode is very special because it was picked by the Making Coffee Podcast Patrons. I sent my patrons a poll on what they wanted to hear about next and the topic most people wanted to hear about was HOW fermentation impacts coffee flavor.  How can the same yeast that makes bread rise also make my coffee taste like apricot or jasmine? Maybe you’ve thought that farmers added fruit to th...

Join me in listening to this conversation with George Howell, where we cover topics such as Cup of Excellence, coffee pricing, processing styles, craftsmanship, additives in processing, kamikaze farmers, and much more. George was awarded the Lifetime Achievement award from the SCA in 1996, even before he helped found the Cup of Excellence program in 1999. He's accomplished a lot towards impro...

Hello friends, Today I want to share an interview with Sofia Handtke from Mapache Coffee in El Salvador. I recorded this last November at the end of my time with them. That was my second season working with them and designing fermentation lots at their mill. Over the last 2 harvest seasons we've done about 40 different batches combining 4 strains of yeast, 3 cultivars and various lengths (# o...

I'm at the halfway mark of this trip and I officially ran out of coffee. I mentioned before that a significant portion of my carry-on space was dedicated to roasted coffee. Bringing coffee from home would mean that towards the end I was drinking coffee that was about 2 months old. Generally, I don’t like to drink coffee that is over 2 months old. I don’t like stale coffee but what I’ve found...

Hello friends, In today’s podcast episode I get to do something a little different. Instead of giving you my thoughts on a particular coffee topic, I’m answering questions from 4 different listeners. Ideally I would like to have an episode for each question because they are rich with topics but many listeners have submitted questions through my website. The pile is growing quite large and I think...

When most people hear that I’m going to Central America for work, they often say some variation of “how cool! you’re going to have such great coffee” which is true, but only because I haul most of if myself from The United States back to Central America in my suitcase.  Consuming countries pay a higher price for good coffee - so by design the best coffee leaves the countries where it was produced....

In this episode, I had the chance to speak with Jan-Carlo Handtke of Mapache Coffee.  Jan-Carlo shares important perspectives of what it's like to be a 5th generation producer today. When most people are leaving coffee, Jan-Carlo and his wife Sofia are doubling down, buying new farms and making significant investments in education and equipment. In this conversation we talk about the role of...

I want to start by thanking everyone who has reached out to me and sent questions/comments or just let me know that you enjoy listening. I started this podcast as my offering to chip away at the knowledge gap between coffee producers and consumers In today’s podcast episode we’re going to hear from 2 sides of the value chain in very different parts of the world. Brendan from Semilla Roasters in Ca...

I’m writing this from a hotel in the small town of Ataco, El Salvador. I’ve been away from home for 21 days out what will eventually be 120. It’s currently coffee harvest time in Central America this is the time of the year when I am traveling the most seeing clients at their mills and designing fermentation lots.  This is an interesting industry because of the amount of travel required by many pa...

You heard my experience getting my Q grader license on last weeks episode. Today’s podcast is a continuation of the Q grader discussion but focusing on its role with coffee producers. I mentioned that it’s tempting to use the wine Sommelier certification as a shorthand to describe the Q grader license because the Sommelier’s has been around much longer and its a more familiar term than Q grader. ...
