Coffee is one of the most consumed beverages in the world, yet it remains one of the most misunderstood. Whether you're new to specialty coffee or have been brewing for years, these are the questions we hear most often at Subatras Coffee Works.

"The difference between an average cup and an exceptional cup often comes down to understanding a few simple coffee fundamentals."

20 Coffee Questions Answered

1. What is specialty coffee?

Specialty coffee refers to coffee that has been carefully grown, harvested, processed and roasted to maximise flavour and quality. Unlike commodity coffee, specialty coffee focuses on traceability, freshness and flavour clarity.

2. What is single-origin coffee?

Single-origin coffee comes from one farm, estate or growing region. It allows coffee drinkers to experience the unique characteristics of a specific terroir instead of tasting a blend from multiple locations.

3. What is the difference between Arabica and Robusta coffee?

Arabica is smoother, sweeter and more aromatic, while Robusta is stronger, bolder and naturally higher in caffeine. If you enjoy complexity and nuance, explore our 100% Arabica Medium Dark Roast. If you prefer a stronger cup, our 100% Robusta Medium Dark Roast is a favourite among traditional coffee drinkers.

4. Which coffee has more caffeine?

Robusta contains almost twice the caffeine of Arabica. The higher caffeine content contributes to its stronger flavour profile and thicker body.

5. What is the best coffee for South Indian filter coffee?

For traditional South Indian filter coffee, many coffee lovers prefer Robusta or Arabica-Robusta blends. Our 70-30 Blend and 100% Robusta are particularly well suited for rich decoctions and authentic kaapi.

6. Why do coffee beans have different roast levels?

Roasting transforms green coffee into the aromatic beans we brew. Different roast levels influence flavour, sweetness, body and acidity. Lighter roasts highlight origin character while darker roasts emphasise chocolate and caramel notes.

7. What is a medium-dark roast?

A medium-dark roast balances origin character with roast development. It often delivers chocolate, caramel and nutty notes while preserving some of the bean's natural complexity.

8. How long do coffee beans stay fresh?

Coffee beans are generally at their best within two to six weeks after roasting. Proper storage significantly impacts flavour retention.

9. Should I buy whole beans or ground coffee?

Whole beans remain fresh longer because the aromatic compounds stay protected until grinding. Fresh grinding before brewing provides a noticeably better cup.

10. What is the best way to store coffee?

Store coffee in an airtight container away from heat, moisture and direct sunlight. Avoid refrigeration as condensation can negatively impact flavour.

Fresh coffee isn't just better coffee. It's coffee that still contains the aromas and flavours nature intended.
11. Why does freshly roasted coffee taste better?

Freshly roasted coffee retains volatile aromatic compounds that gradually disappear over time. Fresh beans provide greater complexity and flavour clarity.

12. What brewing method is best for beginners?

The French Press is one of the easiest brewing methods for beginners. It requires minimal equipment and consistently produces a rich, full-bodied cup.

13. What grind size should I use?

French Press uses coarse grinds, pour-over uses medium, espresso requires fine grinding and South Indian filter coffee generally works best with fine-to-medium grinds.

14. What is coffee acidity?

Acidity refers to brightness and liveliness in flavour rather than actual pH levels. Good acidity often produces citrus, berry or fruit-like notes.

15. Why does coffee taste bitter?

Bitterness often results from over-extraction, overly dark roasting or brewing with water that is too hot.

16. Is black coffee healthy?

Black coffee contains antioxidants and very few calories. When consumed without sugar or cream, it can be part of a balanced lifestyle.

17. What is farm-to-cup coffee?

Farm-to-cup coffee means the producer maintains visibility and control across cultivation, processing, roasting and delivery. Explore our collection of farm-to-cup coffees here.

18. Why does coffee origin matter?

Altitude, climate, soil composition and processing methods all influence flavour. Coffee from different origins can taste dramatically different even when roasted similarly.

19. Why is Chikmagalur famous for coffee?

Chikmagalur is widely regarded as the birthplace of coffee cultivation in India. Its climate and altitude make it one of the country's most respected coffee-growing regions. Our Arabica, Robusta and 80-20 Blend are sourced from this remarkable region.

20. How do I choose the right coffee for my taste?

If you enjoy smooth and aromatic coffee, choose 100% Arabica. For bold strength, choose 100% Robusta. For balance, explore our 70-30 Blend or 80-20 Blend.

Great coffee begins long before brewing. It starts with the bean, the farm and the care taken at every stage.

Final Thoughts

Understanding coffee helps you make better choices, brew better cups and appreciate the work that goes into every bean. Whether you prefer smooth Arabica, bold Robusta or a carefully balanced blend, freshness and traceability make all the difference.
