Japanese Mix Drip Bag Coffee - Medium Dark Roast

☕ Flavor Analysis | Is this the right fit for you?

The defining characteristic of "冰川" is "balanced but not boring." It's not like typical dark roasts that are left with only heavy bitterness, nor is it like lighter roasts that only highlight fruity acidity. Instead, within a medium-dark roast setting, it preserves both fruity brightness and bittersweet body simultaneously. Clear triple flavor profile: Subtle acidity, rich bitterness, and fruity sweetness coexist, making the layers highly memorable.

• Medium-dark roast without flat bitterness: Body and cocoa bittersweetness are spot-on, while preserving fruity highlights.
• Excellent for black / milk coffee: Layers are distinct in black coffee, and the flavor isn't easily masked when milk is added.

📌 Style Highlights (Sensory Evaluation)

Overall style: Subtle fruity acidity upfront, thick and rich mid-palate, with a finish extending into fruity sweetness and a smooth lingering aftertaste (drip bag performance focuses on a more concentrated main flavor line).

📊 Flavor Indicators (Sensory Evaluation)

Flavor Progression (Front / Middle / Finish)

• Front (Head): Subtle fruity acidity leads the way, bringing brightness and a vibrant aroma.
• Middle (Body): Rich bittersweetness and cocoa tones unfold; mouthfeel is smooth and thick.
• Finish (Finish): Fruity sweetness extends, accompanied by a lingering aftertaste and a clean finish; delicate layers.

💧 Drip Bag Brewing Guide | 10g/bag

We use oxygen absorbers for freshness, which packs the coffee grounds tighter inside the bag, potentially causing a slower flow rate during brewing. We recommend tapping the grounds loose first and using a staged, small water flow; this is the easiest way to simultaneously preserve the fruity highlights and cocoa body.

• Suggested Temperature: 89°C–91°C (Try 91°C–92°C to further highlight fruitiness).
• Suggested Water Volume: 155–175ml (10g/bag; choose 155–165ml for a stronger cup, or 170–175ml for a smoother cup).
• Suggested Cup Type: Tall cup (avoid steeping for a cleaner flavor)
• Pouring Rhythm: Bloom for 25–30 seconds + 2–3 pours (small water flow, steady dripping).

✅ Essential Drip Bag Tips (Must Do)

• Tap/Shake to Loosen Grounds (Crucial): Oxygen-free freshness packaging makes the grounds tighter and slows the drip rate; tapping firmly before tearing open improves flow rate and even extraction.
• Do Not Steep: Use a tall cup to keep the drip bag in a dripping state; fruitiness will be cleaner and bittersweetness more balanced.
• Do Not Squeeze the Filter Bag: Remove when almost done dripping; squeezing brings out harsh bitterness and astringency, easily overpowering the fruitiness.

Quick Adjustment Tips:

• For more fruitiness and clearer layers: 91–92°C, 170–175ml, divide into 3 pours → Front-end aroma becomes more prominent, overall profile is more refreshing.
• For milk coffee: Brew a stronger cup with 140–155ml, then add 120–180ml of milk/oat milk → Cocoa bittersweetness becomes steadier, finish still carries fruity sweetness.

Drip Bag Tip: The essence of this blend is the "coexistence of subtle fruity acidity and rich bittersweetness." Loosening the grounds + staged small water flow + no squeezing is the easiest way to preserve the fruity highlights while enjoying a thick, lingering aftertaste.

Supplementary Note

The flavor descriptions on this page are subjective sensory experiences intended to help understand the flavor direction; actual performance may vary based on cup type, pouring rhythm, water temperature, water quality, and personal preference. If the drip bag flows too slowly, it is mostly related to tightly packed grounds; please tap to loosen the coffee bed first and switch to a staged, small water flow, which usually simultaneously improves fruitiness clarity and bittersweet balance.
