How long do bouillon cubes last?
Dry bouillon cubes and broth made from them need different handling. FoodKeeper gives separate pantry quality references from purchase and opening; they are not added together. Knorr US gives label-led flavor advice, while one specific Knorr UK product has a production-based specification.
Quick answer
FoodKeeper lists one year in the pantry from purchase for dry bouillon as a freshness/quality reference. Match a dry product and follow its label.
Purchase does not establish that the package is unopened. Do not add the purchase and opening periods or use either to extend the package date.
FoodKeeper separately lists one year in the pantry after opening for dry bouillon as a quality reference. Knorr US separately advises protecting remaining dry cubes from moisture.
From opening, with the product’s prior age and package date still relevant. FoodKeeper does not explain whether opening an outer carton counts when each cube wrapper stays sealed.
Unilever Food Solutions UK specifies eighteen months from production and cool, dry storage for article 17054602, CU EAN 8722700108214. The 60 × 450 ml designation describes stock yield per cube.
From production only; the specification does not state an opening condition. It gives no new eighteen-month purchase or opening period and does not apply to Knorr US cubes.
Knorr US recommends keeping dry cubes cool and dry, sealing unused cubes airtight after opening, and checking the package date for peak flavor.
Follow the actual package date; this advice gives no separate number of days or months.
FoodKeeper’s bouillon tip gives broth made from dry bouillon three to four refrigerated days. USDA separately advises prompt cooling in shallow portions and continued refrigeration at 40°F or below.
The start at reconstitution is inferred from the prepared-broth context. Count from making the broth, with prompt cooling; reheating does not restart the period.
Why guidance varies
Dry compressed cubes, moist bouillon paste and prepared broth are different forms. Purchase, package opening and production are different starting points, and a UK product specification does not set a period for a US cube.
Match the product state, storage conditions and source clock above. This guide does not provide an automatic expiry timer.
Frequently asked questions
Can I store the broth like the dry cubes?
No. Broth made from cubes is a prepared food. Cool it promptly in shallow portions and keep it refrigerated at 40°F or below under USDA guidance; the dry-cube pantry periods do not apply.
Do Knorr’s paste instructions apply to cubes?
No. Knorr US discusses cubes, granules and moist paste separately. Follow the instructions for dry cubes rather than transferring a paste or liquid-stock keeping period.
Does the UK eighteen-month specification apply to my US pack?
No. It belongs to the identified UK chicken cube article and begins at production. Use the actual local product label rather than converting it to purchase or opening time.
