(g) For purposes of this chapter, it is presumed that liquors are possessed for the purpose of sale in this state if the quantity of liquors possessed in this state, imported or caused to be imported into this state or produced, distilled, manufactured, compounded, mixed or fermented in this state exceeds ninety liters. Such presumption may be rebutted by the introduction of substantial evidence to the contrary. In any case where the quantity of alcoholic beverages taxable pursuant to this article is a fractional part of one liter (or one gallon in the case of beers) or an amount greater than a whole multiple of liters (or gallons in the case of beers), the amount of tax levied and imposed on such fractional part of one liter (or one gallon in the case of beers), or fractional part of a liter (or gallon) in excess of a whole multiple of liters or gallons shall be such fractional part of the rate imposed by paragraphs (a) through (f). Notwithstanding any other provision of this article, the commissioner may permit the purchase of alcoholic beverages without tax by a person registered as a distributor under section four hundred twenty-one of this article from another person so registered , in which event the alcoholic beverage so purchased shall be subject to the taxes imposed by this article in the hands of the purchaser in the same manner and to the same extent as if such purchaser had imported or caused the same to be imported into this state or had produced, distilled, manufactured, brewed, compounded, mixed or fermented the same within this state.
