What it is
Cold fill means product goes into the container at ambient or refrigerated temperature instead of being heated first. Because there is no thermal step in the bottle, cold fill protects volatile aromatics, fresh herbs, citrus oils and living cultures — but it puts the entire burden of shelf stability on formulation, pH, water activity, preservatives and a sanitary filling environment.

Brands that belong here
Plan around these
- — Shelf life is shorter than hot fill unless the formula is engineered for it
- — Requires documented pH targets before a first run is scheduled
- — Cold-chain distribution may be required, which changes your freight math
Common questions
What is cold fill bottling?
Cold fill bottling fills product into containers at ambient or refrigerated temperature with no in-bottle heat step, relying on formulation controls — pH, water activity, preservatives — and a sanitary filling environment for stability.
When should a brand choose cold fill over hot fill?
Choose cold fill when heat damages the product: fresh citrus, herbs, aromatics, cultures or cold-pressed juice. Choose hot fill when you need long ambient shelf life on a retail shelf.
