An aluminum-canned wine comprising: an aluminum can including an aluminum sheet, a resin film provided on a surface of the aluminum sheet which faces an internal space of the aluminum can, and an adhesive layer interposed between the aluminum sheet and the resin film and bonding the aluminum sheet and the resin film together, wherein the resin film includes a first resin layer as a topmost layer and a second resin layer containing a dimer acid-copolymerized polyester resin, and wherein at least one of the resin layers constituting the resin film, and/or the adhesive layer contains calcium carbonate; and a wine enclosed in the aluminum can and containing 4.3 mg/L or less of molecular SOand 350 mg/L or less of chloride ions.

Aluminum-canned wine and aluminum can to be filled with wine

A method for determining a reference value of a wine for feasibility of filling an aluminum can, the method comprising: acquiring a pH, an alcohol concentration, and a free sulfite concentration for multiple kinds of wines; calculating a molecular SOconcentration of each of the multiple kinds of wines from acquired values of the pH, the alcohol concentration, and the free sulfite concentration; enclosing the multiple kinds of wines into aluminum cans of an identical type, respectively, thereby obtaining multiple kinds of canned wines; putting the multiple kinds of canned wines in storage and evaluating quality of the canned wines after the storage; and determining an upper limit value of the molecular SOconcentration based on an evaluation result obtained from the evaluating.
