How long does Soy Milk last?
In the fridge: 7 days
In the freezer: 60 days
In the pantry: 365 days
Soy milk lasts 7–10 days in the fridge once opened, kept below 4°C. Sealed shelf-stable cartons last a year or more. Refrigerated fresh soy milk has a much shorter shelf life — check the use-by date. Once opened, the protein content makes it spoil similarly to dairy milk; sour smell, curdling, or off taste are the warning signs. Shake before each use to redistribute settled solids.
