Should I shake kombucha before drinking?
Usually no — shaking kombucha stirs up sediment and can fizz over like a shaken soda. Gentle invert or roll if you want yeast mixed; open slowly over a sink after chilling. The same pressure caution applies to bottle-conditioned sparkling cider.

Key facts
- Carbonation. Finished kombucha is often lively; TTB notes ongoing fermentation can raise pressure and alcohol. [1] [2]
- Default. Do not hard-shake refrigerated kombucha.
- Sediment. Yeast at the bottom is normal; swirling gently redistributes it.
- Pressure. Warm bottles foam more — chill before opening.

When is a gentle roll useful?
If you prefer a cloudy pour with yeast in suspension, tip the bottle slowly rather than shaking. Keep the bottle cold first — warm kombucha foams harder when the seal breaks. Sparkling cider opening habits differ: how to open a sparkling cider bottle.
Does shaking change flavour permanently?
It mainly changes texture and CO₂ release in the glass, not the recipe. Sediment redistributes for one pour; shaking does not create lasting bubbles if the bottle was already flat. Compare alcohol risk: does kombucha have alcohol. Guide: what is cider.
