Please note: If you order this large 25kg bag of dextrose, you will need to have your order sent by courier, because it isn't possible to use Australia Post for products that are this big and bulky. Dextrose is ideal for the priming of beer bottles for secondary fermentation. It improves the quality of beer. It is fully fermentable and leaves a fresh, clean flavour with no cidery aftertaste, and minimum sediment.
