| Aspect | Regular Yogurt | Greek Yogurt | Impact |
|---|---|
| Milk Requirement | 1L milk = 1L yogurt | 3-4L milk = 1L yogurt | Higher raw material cost |
| Fermentation Time | 6-8 hours | 5-7 hours | Slightly shorter |
| Additional Step | None | Straining (2-4 hours) | Extra equipment needed |
| Yield | 95-100% | 30-40% | Lower output per batch |
| Shelf Life | 14-21 days | 21-28 days | Longer due to lower moisture |
