Claim 1
Independent Claim
90 words
A PROCESS FOR STABILIZATION OF VODKA CONSISTING ESSENTIALLY OF THE STEPS OF TREATING VODKA IN THE LIQUID PHASE WITH ACTIVATED CHARCOAL TO REMOVE OR DECREASE THE CONCENTRATION OF CONGENERICS RESPONSIBLE FOR TASTE AND ODOR IN SAID VODKA AND TREATING THE CHARCOAL-TREATED VODKA WITH A HIGHLY-CROSSLINKED NUCLEAR SULFONIC MECROPROUS POLYSTYRENE CATIONIC EXCHANGE RESIN TO REMOVE POLYVALENT CALCIUM AND MAGANESE IONS INTRODUCED INTO SAID VODKA BY SAID TREATMENT WITH ACTIVATED CHARCOAL AND TO CONTROL THE PH OF THE VODKA SO THAT IT LIES WITHIN THE RANGE OF ABOUT 7.2 TO ABOUT 9.
