FAQs

What is specialty coffee?

Specialty coffee refers to high-quality coffee beans that are graded 80 points or higher on a 100-point scale by certified Q-Graders under standards established by the Specialty Coffee Association (SCA).

These beans are carefully grown, processed, and roasted to highlight their unique flavor profiles and origin characteristics.

How is specialty coffee graded?

Specialty coffee goes through a detailed evaluation process:

  1. Green Bean Inspection – Beans are assessed for defects, size, and overall quality.

  2. Roasting & Cupping – After roasting, experts evaluate aroma, flavor, body, acidity, and aftertaste.

  3. Scoring – A final score is assigned based on these attributes.

Only coffees scoring 80+ qualify as specialty grade.

What types of beans are used in specialty coffee?

The two primary coffee species are:

  • Arabica – Preferred in specialty coffee for its smoother, more complex flavor and lower bitterness.

  • Robusta – Stronger, more bitter, and contains nearly twice the caffeine of Arabica.

At Adult Fuel Coffee, we focus on sourcing high-quality beans that deliver bold flavor and consistency.

Where does specialty coffee come from?

Specialty coffee is sourced from regions around the world, including:

  • Indonesia (Sumatra & Bali)

  • East Africa

  • South America

  • Central America

Each region offers distinct flavor characteristics — from chocolatey and nutty to bright and fruity. At Adult Fuel Coffee, we curate selections to make sure there’s something for every coffee lover.

How should I choose coffee for my brewing method?

At Adult Fuel Coffee, we make it easy to choose the right roast for your preferred brew method:

Espresso:
Medium-dark roasts from Latin America or East Africa.

Cold Brew:
Medium to dark roasts with chocolate, caramel, or nutty notes.

French Press:
Medium-dark to dark roasts for bold, full-bodied flavor.

Pour Over:
Light to medium-light roasts with bright acidity and complexity.

These are general recommendations — you can enjoy any coffee with any brew method based on your personal taste.

Is specialty grade coffee good for your health?

Moderate coffee consumption has been associated with potential health benefits, including a reduced risk of certain conditions such as Type 2 diabetes and Parkinson’s disease, according to public health research.

Specialty-grade, Q-scored beans are often carefully sourced and processed, which may help preserve natural antioxidants and beneficial compounds.

However, coffee affects everyone differently. Always consult your healthcare provider with specific medical concerns.

What is the best way to brew coffee at home?

The best method depends on your taste preferences and lifestyle:

  • French Press – Bold and full-bodied

  • Pour Over – Clean and nuanced

  • Drip Machine – Convenient and consistent

  • Espresso Machine or AeroPress – Rich and intense

Experiment to find what fuels you best.

How much caffeine is in a cup of coffee?

Caffeine content varies by brewing method and bean type. On average:

  • Drip Coffee: 95–200 mg per 8 oz

  • Espresso: 63 mg per 1 oz shot

  • Cold Brew: 100–200 mg per 8 oz (can be higher due to concentration)

Robusta beans contain nearly twice the caffeine of Arabica beans.

Is coffee good or bad for your health?

In moderation, coffee is generally considered safe for most adults. It contains antioxidants and may provide certain health benefits.

However, excessive caffeine intake may cause:

  • Anxiety

  • Sleep disruption

  • Digestive discomfort

Listen to your body and consult a medical professional if you have concerns.

What’s the difference between Arabica and Robusta?

Arabica:

  • Smoother and sweeter

  • Notes of fruit and sugar

  • Lower caffeine content

Robusta:

  • Stronger and more bitter

  • Earthy or nutty flavors

  • Higher caffeine

  • Often used in espresso blends for added crema and intensity

How should I store coffee beans?

To keep your coffee fresh:

  • Store in an airtight container

  • Keep away from light, heat, moisture, and air

  • Avoid the fridge or freezer unless vacuum-sealed for long-term storage

  • Use within 2–4 weeks of opening for best flavor

What grind size should I use?

Matching grind size to brew method is essential:

  • Coarse: French press, cold brew

  • Medium-Coarse: Chemex

  • Medium: Drip machines, AeroPress (longer brew)

  • Fine: Pour-over, AeroPress (short brew)

  • Extra Fine: Espresso, Moka pot

  • Ultra Fine (Powder): Turkish coffee

How is decaf coffee made?

Decaf coffee is created by removing caffeine from green coffee beans using one of several methods:

  • Swiss Water Process® (chemical-free) – The only decaf method used by Adult Fuel Coffee

  • CO₂ Process

  • Solvent-based methods (ethyl acetate or methylene chloride)

Most decaffeination methods remove approximately 97–99% of caffeine while preserving flavor.

What makes specialty coffee different from regular coffee?

Specialty coffee:

  • Scores 80+ by certified graders

  • Uses high-quality beans

  • Has traceable origins

  • Is ethically sourced

  • Is carefully roasted for flavor clarity

It’s about flavor, transparency, and quality — not just caffeine.

Can I make espresso without a machine?

Yes, you can get close using:

  • AeroPress (with metal filter and fine grind)

  • Moka pot (stovetop espresso)

  • Manual lever espresso makers

While not true espresso (due to pressure differences), these methods produce a strong, concentrated brew.

What do roast levels mean?

Light Roast:
Bright, acidic, origin-forward flavors. Slightly more caffeine retained.

Medium Roast:
Balanced acidity and body. Smooth and versatile.

Dark Roast:
Bold, smoky, lower acidity. Sometimes more bitter.

Choose based on flavor preference — not caffeine myths. Light roasts generally retain slightly more caffeine than dark roasts.
