What is Hartmann Coffee Bean Wine Processing Method? Origin Information Estate Flavor Description

The Wine Processing Method

The wine processing method is also known as the controlled fermentation method, or the lactic/acetic acid fermentation method.

The experimental team is led by American Felipe Sardi and made up of biological scientists and ecologists. They apply technologies such as solar energy to cultivation and green bean processing.

A dedicated hand-picking team is trained to follow strict specialty coffee picking standards: unripe cherries below 2%, defective beans below 3%, floaters below 5%.

Acetic Acid Fermentation—Aerobic Fermentation

Lactic Acid Fermentation—Anaerobic Fermentation

Expected Flavor Profiles

Acetic Acid Fermentation:

Cleaner cup, lively and brighter acidity, citric acid.

Lactic Acid Fermentation:

Rounder mouthfeel, slightly less clean than acetic fermentation, higher body, malic/tartaric acid.

In the past, processing plants relied on traditional hands-on methods passed down through generations—like biting into a coffee bean to judge the degree of fermentation. That kind of fermentation is uncontrollable and unpredictable.

The controlled fermentation method uses pH monitoring to track fermentation, delivering predictable results and consistent output from batch to batch.

The Caturra Variety

Caturra is a single-gene mutation of Bourbon, discovered in Brazil in 1937. It yields better and resists disease better than Bourbon, and its shorter tree height makes harvesting easier. Unfortunately, like Bourbon, it suffers from biennial bearing cycles. On the plus side, it adapts readily, needs no shade trees, and thrives in direct intense sunlight—hence its nickname, "Sun Coffee." It tolerates high-density planting but demands more fertilizer, which raises costs, so farmers were slow to accept it at first.

In the 1970s, however, when coffee prices rose sharply, farmers switched to Caturra to boost production. With vigorous promotion by the Brazilian and Colombian authorities, the results were impressive. Accepting Caturra meant a major shift in cultivation technique: Brazil and Colombia adopted high-yield, high-density sun cultivation. By 1990, one million hectares were harvesting 14 million bags of coffee, an increase in productive capacity of 60%. No wonder high-yielding, high-quality Caturra became a workhorse variety for producing countries everywhere.

Caturra can be planted anywhere from low altitudes of 700 meters up to 1700 meters, showing strong altitude adaptability. The higher the altitude, the better the flavor—but the lower the yield. That is the fate of specialty beans. Academics call Caturra the intensive, sun-grown version of Bourbon, which is quite fitting. A yellow-fruited variant (Caturra Amarello) also exists in Central and South America, though its reputation doesn't match Yellow Bourbon.

Lightly roasted, Caturra shows an obvious acidic aroma and overall brightness, and with careful processing the sweetness can be excellent. Its body, however, is comparatively low next to Bourbon, and the mouthfeel is slightly less clean.

Caturra usually bears red cherries, but in extremely rare pockets—such as Hawaii—small amounts of yellow Caturra are cultivated.

An Introduction to Hartmann Estate

The Hartmann story is every bit as legendary as its coffee. Hartmann Estate sits in Santa Clara, Chiriquí Province. Its founder, Mr. Alois St. Hartmann (Luis Hartmann), was born on June 20, 1891, in the Moravia region of Austria-Hungary—in what is now the Czech Republic—and died on May 25, 1970, at the age of 78.

After World War I broke out, he was abandoned as a young boy. Thanks to his mother, he survived by hiding aboard a ship bound for Pennsylvania, USA. His two brothers both died in the war after joining the army. Luis Hartmann traveled through several countries with friends until he reached Panama in 1911 and settled in Chiriquí Province in 1912, living mainly around the Candelaria area, where he built the first small cabin in that pristine forest.

Today's Hartmann Estate is a family business founded in 1940 by Ratibor Hartmann, Luis's son. In 1966, Ratibor married Dinora Zúñiga from Costa Rica. They had five children: Ratibor Jr., Allan, Alexander, Alice, and Kelly. Each family member takes charge of part of the operation—cultivation management, harvesting and processing, and estate tours. A family that has grown coffee for over 100 years is itself the stuff of legend.

Brewing Recommendations

Pour-over for Hartmann: 15g of coffee, medium grind (setting 4 on a small Fuji ghost-tooth burr grinder), V60 dripper, water at 88-89°C. First pour 30g of water and bloom for 27 seconds. Pour up to 105g and stop. Wait until the water level in the coffee bed drops to half, then pour again, slowly, up to 225g. Skip the tail end of the drawdown. Water-to-coffee ratio 1:15. Extraction time 2:00.

This family business also runs a province-level cupping laboratory and sample roasting room, and strictly cups every single batch of coffee. That discipline ensures the stable quality of Hartmann Estate's coffee and its constant drive to improve. A scientific attitude toward coffee plus nearly 100 years of family experience guarantee the excellence of what they produce.

A legendary estate with a province-level cupping laboratory and sample roasting room: rigorous methods and strict standards keep Hartmann Estate's coffee quality remarkably consistent.

Tasting Notes

This batch is Caturra processed by the wine method. From the first grind it releases an intensely rich fruit-wine aroma, joined by fresh smoked-wood spice notes and the special berry sweetness of natural processing—one breath of it and you're already won over. On the palate it floods with tropical fruit, like a cocktail carefully mixed from passion fruit, mango, orange, and berry juices with peach wine! No—not a cocktail from any bar, but one made by nature itself!

Of all the coffee regions on Earth, very few have successfully experimented with wine-like processing. After years of testing, this method can finally control the acidity structure in coffee. Coffee fermented this way gains dramatically in sweetness, cleanliness, and layered, complex-yet-elegant acidity. It is a fermentation approach that lifts both the quality and the distinctiveness of the final cup.

FrontStreet Coffee Recommendation

If the wine-processed Hartmann has you curious about how origin shapes the cup, FrontStreet Coffee's Brazil Cerrado Red Bourbon is a wonderful point of comparison. Cerrado is one of Brazil's most respected coffee regions, and this classic single origin, roasted medium, opens with aromas of creamed peanuts, toasted bread, caramel, and hazelnut. The cup is round and mellow—no sharp acidity, just a gentle bitterness—making it an easy daily drinker for pour-over, moka pot, siphon, French press, or espresso SOE.

For a different side of Brazil, FrontStreet Coffee's Queen Estate Yellow Bourbon comes from Mogiana, near Sul de Minas, where rich red volcanic soil feeds the cherries. Yellow Bourbon is a natural mutation of Red Bourbon with an even cleaner fruit profile, and hand-brewed it reveals a sugarcane sweetness you won't find in other origins, alongside fruit and chocolate notes.

As Brazil is also the backbone of many great espresso blends, you can find it in FrontStreet Coffee's espresso series—the crema-rich Classic Blend, the nut-forward Signature Blend, the balanced Black Cocoa Blend, and the shop-focused Commercial Blend—where Brazilian beans lend chocolate and cream aromas, soft acidity, and a stability that makes extraction forgiving.
