Costa Rica Aquiares Anaerobic Review: A Journey into Fermentation Flavors

Costa Rica has long been a benchmark for clean, bright coffee, but the Aquiares Anaerobic from Friedhats Coffee Roasters takes a bold step into the world of controlled fermentation. This single origin is not your everyday cup—it’s a deliberate experiment in processing that transforms how we perceive fruit, acidity, and body. Grown on the slopes of the Turrialba volcano, the Aquiares farm is known for its sustainable practices and micro-lot innovations. Here, the coffee cherries undergo anaerobic fermentation in sealed tanks, which amplifies their inherent sweetness and introduces complex, wine-like characteristics. If you’ve been curious about what ‘fermentation’ really tastes like in coffee, this bean is your definitive tasting note.

In this product review, we’ll explore the sensory profile of the Costa Rica Aquiares Anaerobic, break down its processing method, and offer practical brewing advice to unlock its full potential. Whether you’re a seasoned specialty coffee enthusiast or a curious newcomer, this coffee challenges expectations. We’ll also compare it with other offerings from Friedhats—like the Colombia Diego Horta Infused Gesha Omni—to highlight how fermentation can be a spectrum rather than a single note. Let’s dive into the cup.

What Makes Anaerobic Processing Special?

Anaerobic processing is a post-harvest technique where coffee cherries are placed in sealed, oxygen-free tanks for a controlled duration. Unlike traditional washed or natural methods, anaerobic fermentation allows producers to manipulate temperature, pressure, and duration to create distinct flavor profiles. In the case of the Costa Rica Aquiares Anaerobic, the cherries ferment for several days before being dried. This process concentrates the fruit’s sugars and develops lactic acid compounds, which can manifest as buttery, creamy, or even fruity tastes. The result is a coffee that often feels fuller and more intense than its air-dried counterparts.

For Friedhats, this cup represents a commitment to experimental transparency. The roastery sources directly from the Aquiares farm, ensuring traceability from tree to bag. The anaerobic process here is subtle—not overwhelming—allowing the Caturra and Catuai varieties to shine. Compared to a classic washed coffee like Guatemala Micaela Jacinto Washed, which emphasizes clarity and floral acidity, the Aquiares Anaerobic offers a more textured, wine-like experience. It’s a fantastic entry point for understanding how fermentation can deepen a coffee’s character without losing its origin identity.

• Tip: Let the coffee rest at least 7–10 days after roast date to allow fermentation gases to dissipate, revealing a cleaner, more balanced cup.

Tasting Notes and Flavor Profile

When brewing the Costa Rica Aquiares Anaerobic, expect a complex aroma reminiscent of dark berries, red wine, and a hint of dark chocolate. The first sip reveals a juicy acidity—like ripe cherries or plums—that quickly gives way to a silky, full body. The finish is surprisingly clean, with a lingering sweetness akin to brown sugar or molasses. There’s no sourness or funkiness here; instead, the fermentation brings a controlled, elegant fruitiness. The coffee’s medium roast preserves these characteristics while ensuring a smooth, approachable drinkability.

In our cupping, we found that the Costa Rica Aquiares Anaerobic pairs wonderfully with milk-based drinks (try a cortado) or as a pour-over. Its profile is distinct from the Colombia Diego Horta Infused Gesha Omni, which uses a different style of infusion—yeast-based—to create more pronounced, almost wine-like flavors. The Aquiares leans more toward natural sweetness and subtle fermentation, making it a versatile choice for both filter and espresso. For those who enjoy exploration, this single origin is a rewarding challenge to traditional expectations.

• Aroma: Dark berries, red wine, cocoa
• Acidity: Juicy, cherry-like, balanced
• Body: Silky, full, with a creamy mouthfeel
• Finish: Clean brown sugar sweetness

Brewing Recommendations

To fully appreciate the fermentation notes, we recommend a pour-over method using a V60 or Chemex. Use water at 93°C and a medium-fine grind size. Aim for a 1:16 coffee-to-water ratio. Start with a 30-second bloom, then pour in stages. This highlights the coffee’s bright acidity and silky body. For espresso, try a shorter ratio (1:2) to focus on the chocolatey sweetness—the fermentation adds a surprising red wine finish that lingers nicely. If you use an Aeropress, the Aeropress Paper Filters ensure a clean cup, though you might want to experiment with a slightly coarser grind to avoid over-extraction.

Remember that anaerobic coffees can be more sensitive to water temperature. Too hot, and you might extract bitter compounds; too cool, and the acidity becomes sharp. Stick to 92–94°C and adjust your grind to taste. The Costa Rica Aquiares Anaerobic also takes milk well—in a flat white, the fermentation notes transform into a creamy, berry-like flavor that’s quite unique. For a direct comparison, brew it side-by-side with Guatemala Micaela Jacinto Washed to see how processing can change everything while keeping the same origin quality.
