Frequently Asked Questions
Q: Do I really need a scale for pour-over? A: Yes. Volume measurements (scoops) are inconsistent because coffee density varies. A scale eliminates guessing and ensures repeatable results. This is the single biggest improvement home brewers make.
Q: What’s the best pour-over ratio for beginners? A: Start with 1:16 (coffee:water). It’s balanced and forgiving. Once you’re comfortable, experiment with 1:15 for brighter cups or 1:17 for fuller body.
Q: Can I use my kitchen scale instead of a coffee scale? A: Kitchen scales typically only measure to ±5g, which is too imprecise for coffee (a pour-over uses 20-30g coffee total). Coffee scales measure to ±0.1g for accuracy.
Q: How long does a pour-over take with the right ratio? A: 3-4 minutes total. Bloom for 30 seconds with 2x the coffee weight in water, then pour the rest over 2-3 minutes.
Final Recommendation
For beginners: Start with the Timemore Chestnut C2 ($35) and any pour-over dripper. You’ll immediately see improvement in consistency.
For serious home brewers: The Acaia Pearl ($249) is worth the investment if you brew multiple cups daily. The flow rate feedback accelerates your technique improvement.
For balanced budgets: The Hario V60 + Timemore C2 bundle ($89) is our sweet spot—enough precision to dial in excellent coffee without the premium price tag.
The key insight: precision scales matter more than expensive equipment. A $35 scale with a $15 Hario V60 beats a $200 automatic brewer every time because you control the variables.
