Question 1

What exactly is Robusta, and how is it different from Arabica? I’m not a fan of sour coffee, so would Robusta be a good choice for a beginner like me?

Accepted Answer

Robusta and Arabica are two main types of coffee beans.

- **Arabica** is usually smoother and more aromatic. It can taste fruity or bright—sometimes “sour” if it is lightly roasted or brewed in a way that brings out acidity.
- **Robusta** is stronger, more bitter, and has more caffeine. Think of the difference between dark chocolate and milk chocolate: Robusta is often more intense, earthy, and punchy.

If you dislike sour coffee, Robusta *can* be a reasonable choice, especially in espresso or coffee with milk. However, it is not automatically better: some Robusta can taste quite bitter or rough.

For a beginner, the simplest route is usually:
1. Choose a **medium or darker roast** rather than a light roast.
2. Look for words like **sweet, caramel, chocolate, nuts, or mellow**.
3. Avoid coffees described mainly as citrusy, berry-like, or very bright.

You do not have to choose Robusta to avoid sourness. A medium-roasted Arabica blend can be sweet and easy to drink too. Among the coffees in this context, **KASHIWA CAFE 珈茶話’s カシワブレンド** is described as sweet and medium roasted, so it may be a gentler starting point than a very light-roasted coffee.

Question 2

How does anaerobic processing change the flavor compared with a regular natural? I’m curious whether it would suit someone who likes bright, fruity coffees.

Accepted Answer

Anaerobic processing often makes a coffee taste more intense and fermented than a regular natural.

- **Regular natural:** typically fruit-forward, sweet, and jammy, with flavors that can feel like berries or dried fruit. The fruit character is often clear but relatively familiar.
- **Anaerobic natural:** fermented in a low-oxygen environment before or during drying, which can amplify sweetness and create more unusual notes—think boozy fruit, tropical candy, yogurt-like acidity, wine, or spice. The texture can also feel heavier and more syrupy.

If you like **bright, fruity coffees**, anaerobic lots can be a great fit—especially when they retain a clean, juicy acidity. However, some can be more funky or fermenty than you may want. If you prefer crisp citrus, floral notes, and a clean finish, a washed coffee may be more reliable; for example, the washed, light-roasted Kenyan coffee carried by 常盤珈琲焙煎所 赤羽店 could be worth considering.

If you enjoy the sweeter, dried-fruit side of coffee, the Guatemala from Stockfleths—with plum, caramel, and dried-fruit notes—may also be a gentler step toward more fruit-driven profiles.

Question 3

How do Robusta and Liberica differ in flavor and body? I’m curious whether either could fit my preference for bright, fruit-forward coffees.

Accepted Answer

Robusta and Liberica generally sit quite far from the bright, fruit-forward profile you’re looking for.

- **Robusta** tends to be fuller-bodied, more bitter, and more earthy or woody, often with dark chocolate, nutty, and sometimes rubbery notes. It can add a heavy crema and punchy texture, but it rarely delivers the clean, sparkling acidity associated with fruit-forward specialty Arabica.
- **Liberica** is often more unusual and aromatic: think woody, smoky, jackfruit-like, floral, or spice-like character. Its body can feel syrupy or substantial, but the fruit impression is typically tropical and exotic rather than crisp berry, citrus, or stone-fruit acidity.

If you enjoy **bright, clean fruit**, neither would be the most direct match. The **Kenya Specialty** from 常盤珈琲焙煎所 赤羽店 is likely the closer fit: it is a light-roasted, washed Kenyan coffee, a processing and roast style commonly associated with clearer acidity and a more vivid cup than Robusta or Liberica.

If you prefer fruit with more sweetness and a rounder body rather than sharp brightness, the washed Guatemalan Catuai and Bourbon from Stockfleths may also be worth trying. Its listed notes of **plum, caramel, and dried fruit** suggest a sweeter, more mellow fruit profile.

Question 4

What does “anaerobic process” mean in coffee? I’m not a big fan of sour coffee, so would it be a good choice for a beginner like me?

Accepted Answer

“Anaerobic process” means the coffee cherries are fermented in a sealed container with very little or no oxygen before the beans are dried.

This can create bold, unusual flavors—often like tropical fruit, berries, wine, or candy. Think of it like fruit that has become extra ripe and jammy.

If you don’t enjoy sour coffee, it may not be the safest first choice. Anaerobic coffees can be sweet and smooth, but they can also have a noticeable tangy, fermented fruit flavor. The result varies a lot by roast and producer.

For a beginner, I’d suggest choosing a **medium-roast, washed coffee** first. These are often easier to understand and tend to taste cleaner, with familiar notes such as chocolate, caramel, or nuts. If you do try an anaerobic coffee, look for one described as **sweet, chocolatey, or low-acid**, rather than citrusy or wine-like.

Question 5

Show only comparable facts.

Accepted Answer

Robusta and Liberica are unstated. the Guatemala coffee handled by Stockfleths explicitly lists varieties, washed process, and medium roast.
