Ough %T Use of PET Bottles for Wine %D 1987 %R 10.5344/ajev.1987.38.2.100 %J American Journal of Enology and Viticulture %P 100-104 %V 38 %N 2 %X Two separate studies, each covering a year of testing, indicated that comparison of wine bottled in polyethylene terephthalate (PET) to that bottled in glass would depend on the size of the PET container and whether a high barrier material was used as an additional layer of protection. Wine in 3-L PET containers with a Saran layer or 4-L PET containers maintained quality for 10 to 12 months when compared to the same wine in glass containers. Changes in SO2 and color were the most obvious measurable changes. These were due to oxygen permeation. Keeping the level of free SO2 at ca 30 mg/L was effective for the preservation of the samples of white wine studied. Data are presented showing the important measurable changes over the sampling period. %U https://www.ajevonline.org/content/ajev/38/2/100.full.pdf
