Making Coffee with Lucia Solis

Support the show on Patreon to help us keep making new episodes. In this seventh episode, we give you a practical manual to protect the quality you've worked so hard to create, all the way from the coffee tree to the export container. During picking, we look at why heavy jute sacks crush and heat your cherries, and why smaller, ventilated, stackable baskets protect both your fruit and your workers. On the drying patio, we cover what unseasonal rain does to your parchment, from mould to faste...

Support the show on Patreon to help us keep making new episodes. In this sixth episode, we give you a practical manual to judge your own coffee quality, so you can negotiate with buyers on a level playing field. We start with the simplest step of all: drinking your own coffee. We cover how to brew and taste it, how to build a catalogue of its flavours, and why tasting your neighbours' coffees in a monthly tasting club gives you negotiating power. Then we look at sample roasting, and why a pro...

Support the show on Patreon to help us keep making new episodes. In this fifth episode, we give you a practical guide to pricing your coffee to ensure your farm is economically sustainable in the long term. We start by showing you how the “C” price is actually set, and why it is not what your coffee is worth. Next, we show you how to calculate your cost of production and the common challenges producers will face doing this for the first time. We then look at how high above your cost of pr...

Support the show on Patreon In this fourth episode, we give you a practical guide to finding buyers and selling your coffee into the specialty market. And we finish with the sales conversation itself: the questions to ask in your first five minutes with a buyer, and how to handle the rejection that's coming, because it is coming. The Coffee Producer Toolkit is the podcast that helps you run a more profitable coffee farm. Hosted by coffee journalist James Harper (Filter Stories podcast) and f...

Support the show on Patreon In this third episode, we give you a practical manual to take control of your fermentations and improve your farm's profitability. We start with the basics — what is actually happening inside your tank, where the microbes come from, and why your coffee is going to ferment whether you want it to or not. Then we go through five ways commercial microbes can make you money: consistency batch to batch, long fermentations you can run safely, lifting the scor...

In this second episode, we show you how to stop losing coffee to a badly calibrated pulper, why chasing 100% ripe cherries is actually costing you money, the $480 fix that lets a small farm sort cherries perfectly well, how to keep your coffee under 40°C during drying without spending a fortune, why a mechanical dryer isn't the villain everyone says it is, the cheap instruments that will deliver consistent quality across harvests, and ways to treat your wastewater. The Coffee Producer T...

The Coffee Producer Toolkit is the podcast that can help you run a more profitable coffee farm.

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 ...

On today's episode I will be updating you on the coffee we made this harvest season and speaking of the importance of blends. If you’ve listened to even 1 other episode of this podcast, you’ll know that I'm usually trying to discourage the coffee industry from blindly adopting wine culture. Usually I share my thoughts that adopting a wine model benefits consumers more than producers and further accentuates inequality between the coffee buyers and coffee producers. Usually I believe the wine m...

This episode also comes on the heels of our recent trip to London. Our very first stop was the Nagare coffee shop in Shoreditch in North London. Nick and I do what we usually do when we step into a coffee shop and order the pour overs.

During our plan for FTC Indonesia, I handed over many of the logistics to the Bandung ...

The conversation with Tom Owen is wide ranging, but one main theme we talk about is coffee travel and tourism. How the host and guest dynamics play out including the unintentional burden we may be placing on coffee producers when we visit them.

Next time you set about making your morning coffee, take a moment to peruse the info on your bag of beans. What do you notice? The variety of beans? Flavor notes?

Do you drink kombucha? Coming from California, kombucha is about as normal as orange juice. But I imagine it might not be as popular in other parts of the world. Kombucha is probably more popular in North America and Europe (coffee importing countries) and probably very rare in coffee producing countries. I can imagine a near future where buyers are drawn to or supportive of kombucha process without understanding what they may be asking producers to do. Or similarly, producers wanting to be ...

Today's episode is another in a series hearing from coffee producers from all parts of the world. I think one of the common traps we can get into is thinking and talking about "The" coffee farmer. Or "The Average Coffee Farmer." As if coffee farmers are a monolith. The average doesn’t exist. The people who grow and produce coffee are a very diverse group who do it for different reasons in very different conditions. It’s our nature, that when we learn something new, to compare it to what...

Today’s questions all come from Dr. Mack in Bangkok, Thailand. Even though he is asking the question on behalf of coffee producers in Thailand, I wanted to answer them on the podcast because they are relevant to all of the newer coffee producing regions.

This is very recent and not a lot of time for coffee growers and producers to develop their craft and catch up with older coffee growing regions like Colombia, where I am living. Colombia was alrea...

Our sugar journey is almost complete as we round out the third installment in the Brix series. I hope the previous podcast episodes helped open your mind to some of the challenges we face in talking about sugar in the coffee industry.

And to help illustrate this point I'm sharing a lesson from one of my favorite industries: the cork industry. Specifically cork wine...

I hope the previous podcast episode helped open your mind to some of the challenges we face in talking about sugar in the coffee industry. In today's episode we are adding another element, another piece of the puzzle—the refractometer and the other instruments used to measure sugar.

I think understanding more about ...

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 and therefore all coffee fermentations outside of Ethiopia are non-native fermentations. Episode ...

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 from coffee producers about their motivations and challenges. And even when we do hear from them ...

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 differences we (humans) are able to perceive. One of the example trees in Peter's book are oak trees...

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 sharing research from Dr. Amiee Dudley. I met Dr. Aimee Dudley in 2017 during SCA EXPO in Seattle w...

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" to the test it cannot be found. Today's episode starts with the story of the 1976 Judgement of Paris tastin...

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 regulated by french law. I cover both of these concerns in todays episode before we get to discuss w...

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 wine industry. We’ve talked about some of the really bad ones, like using wine or beer tanks to ferme...

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 was planning this podcast I knew that I wanted it to be a community supported project and that I did not 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 categories but they have very different histories and I think it’s worth trying to de-couple these bever...

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 wanted to record this episode because many Green Buyers ask me what Coffee Producers mean when they label ...

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 over decades as a response to chronically low coffee prices. It's important for me to share this with y...

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 flavor is what’s going to help the industry move closer towards long term stability. I think it’s...

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 the coffee (and while this sometimes happens—it’s not the kind of flavor we are talking about toda...

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.

He's accomplished a lot towards improving coffee quality and educating consumers on several fronts. What I admire most is that he continue...

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.

I wanted to interview Sofia an...

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 is that many of us drink stale coffee. Maybe not on purpose but if you’re not actively paying attentio...

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 it would be more helpful if I could keep answers brief to address a higher number of questions. ...

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. The coffee that remains is the stuff that wasn’t good enough to export and sell, so by des...

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 social media, selling coffee on the local market, and he also shares some of his struggles. We ...

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 Canada gives the roaster perspective and later in the episode we hear from Vivek, a 4th generation...

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 parties along the chain (farmers, producers, exporter, importers, roasters and cafes). All of ...

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. I’ve been guilty of using this shorthand in the past but its both lazy and inaccurate. I fee...

What is a Q Grader? In the coffee industry the Q Grader license is often compared to the sommelier exam in wine—this is a shorthand that can be useful to provide some vague ballpark approximation, but over the next 2 podcast episodes we will see how different these tests are. When I started to get serious about working in the coffee industry I was looking for ways to deepen my knowledge and the Q Grader license seemed like a good place to start. If I wanted to use fermentation techniques to...

I find the term "over fermentation" to be especially annoying. From a biology point of view this term is nonsense. When coffee professionals use this term it's understood to mean a defect, usually vinegar, "boozy" or like rotting fruit. Everyone agrees that it's a negative trait for a coffee to have. I think it's important to be able to identify this trait but I think this label has held fermentation back and made many (producers and roasters alike) shy away from a process that when controll...

If you made it through last week's deep dive about how we talk about and label specialty coffee - you've earned your coffee-nerd badge! This week I want to pull back the lens and talk more broadly about quality and value. Instead of examining the rigidity of microbiology, this week's episode explores the subjective side of preference and what makes something "good". I tell you a little about my coffee tasting history and share the story of the best (and worst) cup of coffee I've ever had. Su...

The first step in expanding the role of processing in the coffee quality conversation is how we label these coffees. I have noticed a lot of redundancy and confusion in how we describe the coffees. I've heard various forms of; fermented coffees, yeasted coffees, anaerobic fermentation, lactic process, acetic process. The labels we use set up the foundation, and I argue that when the labels are inaccurate the whole foundation is compromised. This area of fermentation in specialty coffee is ju...

In this very first episode, I wanted to give you a little background on how I approach coffee processing as a former winemaker and microbiologist. I discuss the similarities and differences in the processing methods of wine and coffee, and how they can impact perception and education within coffee processing. Support the show

A behind the scenes look at one of the world's favorite beverages. Lucia is a former winemaker turned coffee processing consultant. This podcast will talk about the steps in getting a coffee cherry ready for roasting, share current coffee research in microbiology and have interviews with coffee producers in different parts of the world.
