Lower taxes on Mexican microbrews?

A PRI Senator from Baja California introduced a bill to reduce the amount of taxes on microbrewers. According to this article in El Universal, microbreweries are charged about 8 pesos on every liter they produce, but the bill would reduce the tax to 1.6 liters. The major industrial brewers pay about 3.5 pesos for every liter they produce. I hope this passes, but my guess is that this bill comes a little too late in the budget process for the next fiscal year, and all legislators will be leaving office before the negotiations next year.
