How to Scale Your Pour-Over Recipe for Larger Batches
Coffee dose and water scale linearly — but grind size, pour technique, and brew time need adjustments for larger V60 batches to maintain the same extraction quality.
⚡ Quick Answer
Scale coffee dose and water proportionally (keep the same 1:16 ratio), but expect to grind slightly coarser for larger batches because the deeper coffee bed creates more resistance and slows drawdown. Also increase your bloom water proportionally, and extend overall brew time by 30–60 seconds per additional cup. The V60-02 handles up to 30g of coffee; for 4+ cups consider a Chemex or batch brewer instead.
🎯 Key Takeaway: Scale dose and water proportionally. Grind slightly coarser. Bloom proportionally. Expect longer total time. Use V60-03 or Chemex for batches over 500ml.
⚙️ What Scales Linearly vs What Needs Adjustment
Scales directly ✅
- • Coffee dose — multiply by batch multiplier
- • Total water volume — keep your 1:16 ratio
- • Bloom water — scale proportionally (2.5–3x coffee weight)
- • Number of pour stages — keep same pattern, scale volume
Needs adjustment ⚠️
- • Grind size — slightly coarser for deeper beds
- • Total brew time — expect 30–60s longer per extra cup
- • Pour rate — may need to pour faster to prevent overflow
- • Dripper size — V60-02 maxes out around 30g / 500ml
Batch Size Reference
| Cups | Coffee | Water | Bloom | Brew Time | Dripper |
|---|---|---|---|---|---|
| 1 cup | 15g | 240ml | 40ml | 2:30–3:00 | V60-01 or 02 |
| 2 cups | 20g | 320ml | 55ml | 3:00–3:30 | V60-02 |
| 2–3 cups | 25g | 400ml | 65ml | 3:30–4:00 | V60-02 |
| 3–4 cups | 30g | 480ml | 80ml | 4:00–4:30 | V60-02 max |
| 4–6 cups | 40–50g | 640–800ml | Proportional | 5:00+ | Chemex 6-cup |
✅ Tips for Large Batches
- • Pre-warm your carafe or server — larger volumes lose heat faster during brewing
- • Pour in more stages (4–5 pours instead of 3) to avoid overflow with larger doses
- • Grind 1–2 clicks coarser than your single-cup setting as a starting point
- • If drawdown stalls, your grind is too fine for the batch size
- • A temperature-controlled kettle with hold function prevents temperature drop during long multi-pour brews
