In the ever-evolving single-serve market, drip coffee bags have become an essential format for roasters and coffee lovers alike. Combining the convenience of instant coffee with the quality of a pour-over, they are a staple in the industry. However, as the market matures, the choices have diversified.

If you are a coffee roaster or brand manager, you may face a dilemma: Should you stick with the classic V-Shape (Loop Style) or upgrade to the modern UFO Shape (Disc Style)?

Tonchant manufactures both types of filter materials and provides specialized roll film and packaging machinery. We have witnessed firsthand how different filter shapes complement different bean profiles. This analysis will help you select the filter shape that best aligns with your brand positioning and flavor goals.

1. V-Shape (Classic “Hanging Ear”): The Reliable Veteran

The V-shaped drip bag, commonly known as the “Hanging Ear” or “Loop Style,” is the industry standard. It is likely the first image that comes to mind when consumers think of portable drip coffee.

How it works: The filter paper hangs on the cup’s rim via cardboard “ears,” but the bag itself sits deep inside the cup. As hot water is poured, the coffee grounds are partially submerged in the brewed coffee.

Why choose the V-Shape?

• Flavor Profile (Hybrid Extraction): Because the bag sits in the liquid, the extraction is a hybrid of pour-over and immersion (similar to a French Press). This results in a fuller body and a richer mouthfeel.

• Familiarity: It is the market standard. Customers know exactly how to use it, eliminating any learning curve.

• Cost-Effectiveness: Generally, V-shaped materials and packaging processes are highly economical, making them ideal for daily blends or high-volume product lines.

Best Suited For: Medium to dark roasts that emphasize body, chocolate notes, and a rich, bold taste.

2. UFO Shape (Disc Style): The Modern Specialist

The UFO drip bag is a rising star in the specialty coffee world. Resembling a flat disc that “pops up” to sit on top of the cup, it is quickly gaining traction among premium brands.

How it works: Unlike the V-shape, the UFO filter sits entirely above the cup rim. The coffee grounds never come into contact with the brewed liquid below.

Why choose the UFO Shape?

• A True Pour-Over Experience: Since the bag is not submerged, this is a pure filtration method. Water flows through the grounds and drips down, ensuring clarity of flavor and distinct tasting notes.

• Universal Compatibility: A standout feature. The UFO design fits a wide range of diameters—from narrow insulated tumblers to wide-mouthed camping mugs—without slipping.

• The “Blooming” Effect: The wide opening allows users to pour in a circular motion, mimicking the technique of a professional barista. It is visually appealing and allows the aroma to bloom effectively.

Best Suited For: Light to medium roasts, single-origin beans (SOE), and floral or fruity profiles where clarity and acidity are key.

Head-to-Head: Key Differences

If you are still undecided, here is a breakdown of how they compare in performance:

1. Extraction Method

• V-Shape: Combines soaking (immersion) and dripping. Creates a rich, heavy body.

• UFO: Pure drip filtration. Produces a clean, tea-like body that highlights acidity and aroma.

2. Cup Compatibility

• V-Shape: Best for standard-sized mugs. If the cup is too wide, the ears may slip; if too tall, the bag may not reach the water for immersion.

• UFO: Highly versatile. Because it rests on top, it fits almost any container securely, from small tasting cups to large travel mugs.

3. Aesthetics & Branding

• V-Shape: Classic and practical. Symbolizes “Convenience.”

• UFO: Modern and premium. Symbolizes “Specialty Coffee.”
