A 22-hour cold brew extracts more; why might 14 hours taste better?
Show answer & explanation
Answer: Cleaner short steep
Cleaner short steep ✓ — Right. More extraction is not automatically better extraction. In one cold-brew study, coarse grind plus 22 hours raised total dissolved solids, yield, phenolics, and titratable acidity, yet the best sensory scores came from 14 hours with coarse grind. Past a point, extra contact can pull or form notes tasters read as less clean.
More acid is sweeter — Not quite. Acidity can be pleasant in specialty coffee, but more acid is not a simple route to sweetness. The cold-brew study found 22 hours increased titratable acidity, while the stronger overall sensory impression came from shorter extraction. A good cup is a balance of aroma, body, acidity, and bitterness.
Less water dissolves — Not quite. Water does keep dissolving compounds during long cold contact; the measured problem is not that it stops working. The twist is that the extra dissolved material is not all delicious. Longer steeping can raise strength and acid load while making the flavor less clean or less preferred.
