Purity Coffee Farms

From Seed to Cup, the Quest for the Healthiest Coffee Begins on our Farm

It has been over a year since we bought a coffee farm in Colombia with partners who are specialists in the main aspects of the coffee supply chain. Together, we seek to develop and advance systems for producing and exporting the healthiest coffees and to document the conversion of the farm from conventional farming to regenerative organic farming of coffee.

Over the next year, we’ll spotlight different aspects of farming and processing to paint a more detailed picture of the components that make up a healthy coffee and how they support wellness.

One way to look at healthy coffee is “the presence of good stuff and the absence of bad stuff.” We research and strive for the highest levels of the “good stuff” in our coffee: Polyphenols (like CGA), trigonelline, diterpenes, melanoidins, polysaccharides, N-methylpyridinium, β-carbolines, minerals and many other compounds. We test green coffees for some of these and test our roasted coffees for others, and we make decisions for products based on health.

A major area of study for Purity on the farms will be cultivars or varieties of the coffee plant. Are some cultivars able to deliver more health benefits than others? Do some cultivars make people feel better? These are difficult questions to answer because of the inherent complexity of coffee. Coffee “beans” (seeds) are composed of hundreds of compounds that change to hundreds of other compounds during roasting, and different levels of those compounds are extracted during any number of different brewing methods. In other words, the coffee cultivar is just one variable in the possibility of creating healthier coffee.

We use the term “cultivar” instead of “variety” because the plants are cultivated varieties. We avoid the term "varietal" because it has been misused in the coffee industry as a synonym for variety, cultivar and even landrace.

Below is a drone photo of one of the lands (Lot 4) on the farm early last year that needed replanting.

Clearing land for coffee planting

The land had to be cleared of 6,000 old coffee plants that were not producing well. Those plants will be used as firewood on the farm (photo below).

Old coffee plants to be used as firewood

At Purity, we remind ourselves often that when we have decisions to make about our coffees, health should be the primary driver. However, on a farm, we have to consider other factors to make sure the plant can be at its healthiest, such as microclimate, precipitation patterns and amounts, pests and pathogens, and water availability, among others.

From seed to cup, health guides our every decision.

We sent several different green coffee samples to the lab to see if there was some useful nutritional information that might help us decide what to plant. We narrowed down our choices to three different cultivars to test on our farm: purple caturra, pacamara and rose bourbon. Over the course of the year, we planted 24,587 coffee seedlings of these cultivars in five lots that needed replanting.

Below is a view of Lot 4 in August, which shows intercropping of banana plants with the young pacamara and purple caturra coffee in the foreground and older coffee (6-year-old) in the lot in the background. Prior to planting, workers dug the holes for each seedling and added organic compost that was augmented with nutrients and microorganisms to encourage plant growth and prevent fungal infections of the seedlings’ root systems.

Recently planted coffee cultivars

We planted both cultivars in the same lot so that they would have equal experiences in terms of soil composition, rainfall, sunlight, temperature and other inputs. That way, when it is time to harvest, the variables of the cultivar will be able to be measured more accurately (we hope) when we send the samples for laboratory testing for nutrients, antioxidants and minerals.

Here is drone footage of Lot 4 in August:

Below is another photo of Lot 4 in November—4 months after being planted.

We will need to wait about 2 more years before we have a harvest off of this land and are able to send the coffee to the lab for testing. We’ll also be able to measure things like yield per plant, rate of ripening, etc. We’ll also be able to monitor the cultivars as the plants age to see what changes there are in the composition of the coffee over time. In the meantime, our team on the farm will be working with care to help create outstanding, healthy coffees of the future.

It's been an exciting first year! In our quest to be the best source of coffee for your health, we realized that we had to better understand how coffee is grown and what differences we care about that are best for the environment and your health. If you feel that you can contribute in any way, we want to hear from you! Real change often comes from outside the coffee industry, and we are open to any ideas or feedback you may have. Please feel free to drop a line in the comments if you have a question, any suggestions, or a contact that you could make. Thank you for following along with us on this journey!

    Great article! Was wondering about the importance of intercropping bananas with the coffee. Is it a pest deterrent or is there some other symbiotic relationship with the coffee plant?
    Purity Coffee replied:
    Thanks for your feedback and question! Intercropping with bananas adds value in a number of ways, aside from the benefit of employees enjoying the fruit! Banana plants encourage biodiversity (especially birds), which is an important part of regenerative farming. And YES, banana plants help reduce some pests and diseases: Banana-shaded coffee plants have a lower incidence of coffee leaf rust (fungus) and coffee twig borer (larva of a beetle eat through the branches— photo attached) compared to shade from some other trees. Shade is desirable because it lowers the temperature in the coffee canopy by about 4°F, which allows the coffee fruits to ripen more slowly, which generally means higher quality coffee.

    Wow – I wish every producer in our food system cared as much as you do about quality, nutrition and transparency. If so, we’d have a lot healthier population! Thank you for the care you take – it shows in every way.

    You may enjoy the research on www. Nutrition facts.org search videos associated with “coffee”. The plastic waste associated with pods is a concern. Why couldn’t pods be made entirely from foil or cardboard?
    ’ve recently started enjoying your coffee and had some difficulty receiving timely shipments and having Amazon honor your promotion/voucher so I hope your supply chain eases.
    Despite my minor concerns I am grateful for the integrity you are pouring into each cup. Wishing you continued success.

    Hi Pat! Thank you for reading our blog post and taking the time to share your feedback with us. Keeping the coffee fresh is our top priority and we are continuing to research more sustainable options. The pod itself is recyclable and the interior filter and grounds are compostable. The carton is made of recycled cardboard and can be recycled again. Our pods are packaged in sustainable heat resistant #5 BPA-free plastic which is food safe, recyclable, and great at preventing moisture transmission. The interior filter and coffee grounds may be composted, and the box is made of recycled cardboard which may also be recycled again. While some customers prefer the convenience of a pod, we do understand that many are wanting to avoid plastic all together. We are continuing to look for and test alternative materials for the pods. At Purity Coffee we make every decision based on health, and we want to be sure you are getting the coffee as fresh as possible. Currently our pods are sealed using nitrogen, to displace the oxygen and preserve the freshness of the pre-ground coffee. We have yet to find a more sustainable option that is food safe and also keeps the coffee fresh. Feel free to reach out if you have any other questions!

    Excellent, detailed coverage of all that goes into making the finest product possible for such an enjoyable beverage that coffee is.
