Brewing pour-over coffee is a sensory experience. Specialty coffee constantly seeks excellence in filtered coffee extraction. The innovation and development of new products for competitions serve as a springboard for consumers to enjoy improvements in pour-over coffee preparation.

Below, we have prepared a brief summary of the pros and cons of flat-bottom and V60 filters. For this guide, we used Ethiopia Amederado Supernatural.

Flat-bottom filter papers

Used in brewers like Kalita Wave, Fellow Aiden, Orea, April, etc.

Pros

• More even extraction: With a flat base, water tends to distribute more homogeneously over the coffee.
• Easier to use: They are often more forgiving of pouring and grinding errors.
• Sweeter and more balanced cups: They stand out for medium body, sweetness, and stability.
• Lower risk of channeling: The coffee bed is more uniform, helping to prevent over-extracted or under-extracted areas.
• Ideal for consistency: Widely used in coffee shops when reproducibility is desired.

Cons

• Less flavor clarity: Compared to V60, they tend to offer less flavor separation.
• May reduce brightness/acidity: The cup often feels rounder but less vibrant.
• More specific filters: Each dripper may require its own type of paper.
• Flow sometimes slower: Depending on the filter and grind, they can increase extraction time.

Conical V60 filter papers

Used in the Hario V60 dripper and other compatible cones.

Pros

• Greater clarity and definition: Highlights complex notes and flavor separation.
• More control over extraction: Allows for great manipulation of technique, pouring, and flow.
• Cleaner and brighter cups: Ideal for coffees with floral or fruity profiles.
• Wide availability: V60 filters are easy to find.
• Great versatility: They work very well for exploring different coffee profiles.

Cons

• Less forgiving of errors: Small changes in pouring or grinding significantly affect the result.
• Higher risk of channeling: Especially with irregular grinding or poor pouring.
• Higher learning curve: Requires more consistent technique.
• May produce lighter cups: Some people perceive less body.
• Sensitive to paper quality: Different manufacturers significantly alter flow and flavor.

General difference in the cup

• Flat-bottom → more balance, sweetness, and consistency.
• V60 → more clarity, complexity, and aromatic expression.

Which is best?

• If you're looking for ease and consistent results → flat-bottom.
• If you enjoy experimenting and maximizing clarity → V60.
• For very delicate and complex coffees → V60 usually excels.

Finally, the thickness, material, finish, and density of the paper filter also greatly influence the flow and retention of oils. Take this guide as a starting point and start enjoying filtered coffee methods.
