Cafe vs Home Grinding
Commercial cafes approach grinding differently than home baristas. Here's what you should know.
⚡ Quick Answer
Cafes check and adjust grind settings every 30-60 minutes due to environmental changes (humidity, temperature) affecting bean behavior. They grind on-demand for each shot rather than dosing ahead. Commercial grinders have different calibration scales than home grinders—the numbers aren't comparable between brands or models. Home users typically adjust once per bean bag or day, not continuously. This is fine for lower volume but means home shots may drift more throughout the day. Cafes also use grind by weight (gbw) grinders that automatically dispense precise doses, while home users typically time-based dose or single-dose. The fundamental grinding physics are the same—burrs chop beans the same way—but the workflow and adjustment frequency differ significantly.
🎯 Key Takeaway: Cafes adjust grind constantly (hourly); home users adjust less frequently. This is acceptable for lower volume but means checking your shots throughout the day helps consistency.
Key Differences
| Factor | Cafe Approach | Home Approach |
|---|---|---|
| Adjustment frequency | Every 30-60 minutes | Daily or per bag |
| Environmental monitoring | Constant (humidity, temp) | Usually ignored |
| Dosing method | Grind-by-weight (gbw) | Time-based or single-dose |
| Grinder maintenance | Daily cleaning | Weekly or monthly |
| Burr replacement | Every 500-1000 lbs | Every 2-5 years |
| Multiple grinders | Dedicated for each coffee | One grinder, all coffees |
Home Tips From Cafes
- • Purge between grind changes: Run 5-10g through when adjusting
- • Note your settings: Keep a log of grind settings for each bean
- • Check morning vs evening: Your grind may need adjustment as day progresses
- • Seasonal changes: Adjust for humidity changes (summer vs winter)
- • Bean age matters: Staler beans often need finer grind
