The enclosure includes an upper half cover and a lower half cover, which are bonded together by coating a layer of syrup over a joint therebetween. When the syrup is set, a complete enclosure is formed. The dehydrated beverage substance is positioned in the lower half cover before the upper half cover is bonded to the lower half cover. After the complete enclosure is formed, the dehydrated beverage substance is sealed in the enclosure.
