Warranty

Our Product Warranty states that we guarantee the viability of the product in our Malo-lactic culture packages for 6 months from the manufacture date assuming that they have been properly shipped, stored and handled. Our superior packaging material provides 100% oxygen barrier and UV light protection making this exceptional guarantee possible. During this 6 month guaranteed shelf life, some loss of viability is to be expected.

Malo-lactic culture packages will sometimes swell slightly to moderately during shipping or later while properly stored. This is not an indication of deterioration if the package is less than 6 months old and has been properly handled. This is result of trace amounts of nutrients, still available at the time packaging, causing small amount of culture activity and CO2 production.
