Hand-Drip Basics: The Minimal Kit of Gear, Beans and Water

Hand drip is often thought to "need flair and experience," but it is in fact an extremely repeatable brewing method. Pro baristas and home beginners follow the same basics. Nail the first three factors — gear, beans and water ratio — and you can brew a stable cup from day one.

Step 1: Gather your gear

First you need these five items. The lot comes to roughly ¥5,000–8,000. Choosing "something you can use for the long haul" over "cheap for now" works out better in the end.

• Dripper: either a HARIO V60 (from ¥800) or a KALITA Wave (from ¥1,500). The V60 is the most versatile to start with
• Paper filters: the ones made for your dripper. ¥1–2 each
• Server: heatproof glass with measurement marks (from ¥1,000)
• Scale: a kitchen scale that reads to 0.1g (from ¥1,500). A built-in timer is ideal
• Drip kettle: a gooseneck that lets you control the flow (from ¥2,000)

Step 2: Choose your beans

For your first bag, the iron rule is "a single origin, medium roast, 100g, within two weeks of the roast date." Skip the supermarket's 200g-for-¥400 beans and pick a specialty coffee from a local roaster or online.

• Origin candidates: Colombia, Guatemala and Brazil are easy to handle (a good balance of acidity and bitterness)
• Roast level: medium, or medium-dark
• Grind: tell the roaster "medium to medium-fine." If you have a grinder at home, "a touch coarser than granulated sugar"
• Quantity: start with 100g. If you finish it in a week, go to 200g next time. Flavor peaks about two weeks after opening the bag

Step 3: Keep to the water ratio

This is the single most important rule. 15g of water to 1g of beans is the "golden ratio of 1:15." Many specialty-roaster recipes start here too. Once you are used to it, fine-tune to 1:14 (a little stronger) or 1:16 (a little weaker).

• 1 cup (180ml finished): 14g beans + 210g water
• 2 cups (360ml finished): 24g beans + 360g water
• 1 mug (250ml): 17g beans + 250g water

Water temperature: 90–93°C

90–93°C as you pour from the kettle is ideal (100°C straight off the boil is a touch too hot). Even without a thermometer, "wait 30–60 seconds after it boils" lands you around 92°C. Remember light roasts at 93–95°C and dark roasts at 85–88°C and you can adapt.

The actual brew steps (V60 / one cup)

• 0:00 — set the paper in the dripper and rinse it with hot water (removes the papery smell, warms the server too)
• 0:00 — discard the rinse water and add 14g of ground beans. Tap the dripper gently to level the surface
• 0:00–0:30 — bloom: pour twice the bean weight (30g) of water and wait 30 seconds (CO2 escapes and the bed swells)
• 0:30–1:30 — second pour: spiral outward from the center up to 120g
• 1:30–2:30 — third pour: the same way, pouring up to 210g
• ~3:00 — once the water has fully drained from the dripper, the brew is done

Failure patterns and fixes

• "Too sour" → grind a little finer, or raise the water temperature
• "Too bitter" → grind a little coarser, or lower the water temperature
• "Too weak" → add 1g of beans (keep the water the same)
• "Too strong" → take away 1g of beans
• "The taste differs every time" → always weigh the beans and water on a scale. Eyeballing is forbidden

FAQ

Can I start without a grinder?

At first, having the roaster or shop grind it "medium" works fine. But freshly ground is a world apart in aroma, so if you keep at it, a hand grinder is recommended. If you buy it pre-ground, seal it and use it up within two weeks.

V60 or Kalita — which is better?

For a first timer the V60 is versatile and has plenty of recipe info. The flat-bottom Kalita, on the other hand, makes it easier to land the same taste consistently (water pools and it absorbs unevenness in your pour). If unsure, starting with the V60 is fine.

Do I brew light and dark roasts differently?

Keep the 1:15 ratio the same and adjust with water temperature and grind. Light roasts at a higher temp (93–95°C) and slightly finer; dark roasts at a lower temp (85–88°C) and slightly coarser. Even one bean opens up a wider range.

Is the "swirl" pour really necessary?

No need to be precious about it, but the way you pour has a purpose. Pouring in a spiral from the center spreads the water evenly over all the grounds and draws in the grounds at the rim (which stick to the wall and extract poorly). Aim water straight at the rim and only that spot extracts thin, blurring the taste. Pour slowly, aiming for the center and middle — this alone adds a lot of stability. Until you get the feel, just being mindful of pouring slowly from a gooseneck kettle is enough.

What if the brew takes too long, or drains too fast?

For one cup (14–15g of beans), 2–3 minutes is the guide. Too slow (over 3.5 minutes) and the grind may be too fine, or you are pouring too little at once. Too fast (under 1.5 minutes) and it is too coarse. Adjust the grind by just one step to move toward the target time. Brew time is a mirror of "whether the grind is right," so brewing with an eye on the clock speeds up pinning down the cause.

Hand drip is less "cooking" than "a chemistry experiment." Fix the recipe and keep it up for two weeks and the bean's character comes into view. Only then does the journey to find "your own preference" begin. First, let the golden ratio of 1:15 sink into your body.
