In 2012, the share of packaging unit volume accounted for by the various packaging formats in alcoholic drinks saw some small changes. Metal packaging, which used to be the leading packaging format, was overtaken by glass during the review period. This was mainly driven by strong growth in rice wine, where 600ml glass bottles dominate, thus resulting in glass bottles of this pack size seeing high growth rates. In mid-2010, the Taiwanese government negotiated with the US and the EU regarding its plans to reduce the tax on rice wine in Taiwan. The government passed a draft amendment to the Tobacco and Alcohol Tax Law in July 2010, which proposed to reduce the tax on rice wine through reclassifying it as a cooking wine rather than as a distilled spirit, as had previously been the case. This amendment, which came into place in September 2010, reduced the price of local rice wine from NT$50 to NT$25 per bottle on average, which, in turn, increased demand for both rice wine and glass bottles.
