20ml bottle.
Instructions: Pour the contents of this sachet and 100g granulated sugar into a 750ml (US 25 fl. oz.) bottle. Fill 3/4 full with vodka and shake until the sugar has dissolved. Top up the bottle and shake until the contents have fully blended.
Note: It is easiest to dissolve the sugar in your alcohol by placing both in a blender on high for 2-3 minutes.
