These products are best kept in the fridge. This is because, they are ‘raw, live and unpasteurised’ and so full of the heathful gentle bacterias and pro-biotics. If they get warm, they will begin to ferment again, the living bacteria will produce carbon dioxide, the lid may bulge, and liquid may begin to leak out under the pressure. This is perfectly natural and demonstrates the bio-activity of the products. This does not mean the products have ‘gone off’.
