It has only 4% ABV compared to the 5% ABV of the original product but more importantly, the product comes with less than 0.5g of sugar per 100ml (compared to 2.6g per 100ml in the original Kirin Ichiban beer).
According to Japanese food labeling standards the product is therefore allowed to be labeled as zero sugar.
The product will be sold nationwide in 350 and 500-milliliter (12 and 17-ounce) cans. Kirin has ambituous plans with its sugar-free beer as it expects to sell 1.2 million boxes which is about 150,000 hectoliters by the end of this year.
