Coffee flavors are wonderfully diverse, and different processing methods can take a bean in entirely different directions. Today, FrontStreet Coffee introduces several wine-flavored coffees!

1. Rum Barrel Processing

Colombia · San Jose Estate

Region: Caldas, Colombia

Estate: San Jose Estate

Altitude: 1,750 meters

Variety: Castillo

Processing: Fine washed rum barrel fermentation

What Is Rum Barrel Processing?

Coffee destined for fine washed rum barrel fermentation starts as carefully selected Castillo beans of roughly 17–18 screen size. After depulping, the beans are placed in aged oak rum barrels for low-temperature fermentation, then finished through washed processing and dried on raised sun-drying racks.

2. Red Wine Processing

Panama Hartmann Estate, Red Wine Processing

Country: Panama

Grade: SHG

Region: Volcán

Altitude: 1,250–1,700 meters

Processing Method: Red Wine Processing

Variety: Catuai

Estate: Hartmann Estate

The Red Wine Processing Method

Red wine processing — also called carbonic maceration — borrows from winemaking. Unlike traditional winemaking, where grapes are crushed before fermentation, this technique places whole grape clusters into sealed containers filled with CO2. The slow anaerobic fermentation produces a lighter-colored wine with strong fruity aromas and an excellent mouthfeel.

Applied to coffee, the beans are depulped and placed in fermentation tanks — sealed stainless-steel containers flushed with carbon dioxide to expel the oxygen. The cherries then undergo strictly controlled anaerobic fermentation, developing more aromatic compounds and high-quality acidity.

3. Fine Washed Whiskey Sherry Barrel Fermentation

Honduras Sherry Coffee Beans

Country: Honduras

Region: Marcala

Estate: Moca Estate

Altitude: 1,500–1,700 meters

Varieties: Caturra, Catuai, Pacas

Processing: Fine washed whiskey sherry barrel fermentation

The Sherry Barrel

"Sherry barrels" are the casks that sherry bodegas hand off to the whiskey industry for aging. Sherry itself is a famous fortified wine from the sun-drenched Jerez region of southern Spain, and its production must include maturation under the Solera System.

The Solera System is essentially the practice of blending and aging sherries of different vintages after fortification. All barrels are stacked by age — the oldest at the bottom, the youngest on top. Each year, wine is drawn from the bottom barrels for bottling and sale, and replenished from the barrels above.

In the fine washed sherry barrel fermentation method, harvested cherries first go through fine washed processing. The washed beans are then placed into barrels that previously aged whiskey, where they ferment for 30–40 days in a low-temperature environment of around 15–20°C, followed by shade-drying. This fermentation gives the coffee stunning aromatics and a rich, thick mouthfeel.

FrontStreet Coffee Recommendation

If barrel-aging and anaerobic fermentation intrigue you, FrontStreet's Finca Divisia (Dividing Line Estate) Sidra coffee from Colombia explores the same science in a different form. It's processed by anaerobic natural: the coffee ferments in pressurized stainless-steel tanks where temperature, time, and pH are precisely controlled, and the oxygen-free environment transforms into extra tropical-fruit aromatics.

Roasted medium-light, the Sidra shows passion fruit, grape, apricot, and dried-fruit flavors with a juice-like texture — lovely as a pour-over, cold brew, drip bag, or moka pot brew. For a more classic Colombian cup, the FrontStreet washed Huila coffee is roasted medium-dark to highlight dark chocolate and nut sweetness with a rich, full body.

And for home espresso machines and moka pots, baristas recommend the FrontStreet signature espresso blend: Brazil's creamy nuttiness layered with Colombia's dark chocolate bitterness, extracting with fine golden crema and pairing beautifully with milk for a rich, silky latte.
