The color of the "nori" -- dried laver seaweed -- used in the suds was faded due to growing in low nutrient conditions, and was unsuitable for market. During brewing, 400 sheets of the faded nori were added to the malt in the boiling phase, and another 100 sheets during maturation to make 200 liters of the potent potable. Cinderella Nori Draft follows the same brewing process as 100% malt beer, except for seaweed. However, the addition of the sea plant means it cannot be categorized as a true beer under Japanese law, having to settle instead for the label "happoshu," or beerlike beverages with low malt content.
