That trendy new packaging for wine – the plastic bag inside a cardboard box – may cause the wine inside to experience changes in the flavor, aroma and color if the box  is stored at warm temperatures, according to a study published in the Journal of Agricultural and Food Chemistry.

The researchers stored Californian Chardonnay in five different types of wine packaging at three different temperatures for a period of 3 months. The products were evaluated for:

  • aroma
  • taste
  • mouthfeel
  • color

The sensory results were correlated to physical and chemical measurements including:

The researchers found that higher storage temperatures caused the biggest changes in the wines; but, they also discovered that important changes to some of the above named wine attributes were caused by certain types of packaging when exposed to different temperatures. The most significant of these were the changes caused by storing bag-in-box wines at 68 degrees and at 104 degrees Fahrenheit. In both instances, these wines developed a vinegar-like aroma and taste and a yellow color.  All the wines tested, regardless of packaging, aged better when stored at 50 degrees Fahrenheit.
