Learn how to brew a clean, flavorful single cup of pour over coffee using the Hario Baton Dripper 01. This guide covers setup, pouring technique, and common mistakes to avoid.

Quick Answer

The Baton Dripper 01 is designed for a single cup of pour-over coffee. Use a medium-fine grind, a 1:16 coffee-to-water ratio, and a slow, steady pour to get a clean, balanced cup.

Why the Baton Dripper 01 Works for Single Cups

The Baton Dripper 01 is Hario's smallest paperless dripper, making it ideal for a single serving. It uses a bamboo-infused plastic that reduces material by about 50%, which also means it's lighter and heats up faster than ceramic drippers. Because there are no paper ridges or ribs, the brew relies entirely on the flat bottom and small holes for extraction, giving you a clean cup with less bitterness.

Trade-Offs to Know Before You Start

The Baton Dripper 01 does not use paper filters. This means you'll get more natural oils and fine sediment in your cup, which some drinkers enjoy for a fuller mouthfeel. However, it also means you'll need to clean the dripper thoroughly after each use to avoid rancid oil buildup. If you prefer a paper-filtered brew, this dripper may not be your best choice.

Step-by-Step: Brewing with the Baton Dripper 01

Step 1: Rinse and Pre-Heat: Place the Baton Dripper 01 on your mug or server. Pour hot water through the dripper to warm it and the vessel. Discard the rinse water. Common mistake: Skipping pre-heat can cause your brew temperature to drop too fast, leading to under-extraction.
Step 2: Add Ground Coffee: Add 15 grams of medium-fine ground coffee (similar to table salt) to the dripper. Tap gently to level the bed. Checkpoint: Use a scale for accuracy. Too coarse and the water will pass too quickly; too fine and it will clog.
Step 3: Bloom: Pour 30 grams of hot water (just off the boil, about 200°F / 93°C) evenly over the grounds. Wait 30 seconds for the coffee to bloom. Common mistake: Pouring too fast or unevenly can cause channeling and a sour taste.
Step 4: Main Pour: Slowly pour the remaining 210 grams of water in a steady, circular motion, avoiding the edges. Aim to finish the pour by 1:30 total time. Checkpoint: Keep the water level steady. If it drains too fast, your grind is too coarse; if it pools, it's too fine.
Step 5: Let It Drain: Allow the water to fully drain through the coffee bed. The total brew time should be around 2:30 to 3:00 minutes. Common mistake: Removing the dripper before it finishes draining can leave bitter over-extracted coffee on top.
Step 6: Clean the Dripper: Rinse the Baton Dripper 01 with warm water immediately after use. Use a soft brush if needed to remove coffee oils. Checkpoint: Oily residue can build up and affect future brews. Dry the dripper completely before storing.

Product Facts

"Baton" Dripper 01: Hario has reduced the amount of plastic by about 50% by using natural materials like bamboo byproduct in the Baton Series. This makes the dripper lighter and more eco-friendly, and it heats up faster than all-plastic or ceramic models, giving you a more stable brewing temperature.
