Many rosé wines are bottled in clear glass bottles instead of coloured (green or brown) glass. The producers want to show off the beautiful colour of the rosé wines. Rosé wines owe a lot of their success to the colour. Sometimes it is even more important than the taste (oh yes, we’ve heard producer talking about buyers who only care about the colour).
But a clear bottle lets through more UV (ultra violet) light, affecting both the colour and the aromas. A research report shows that colour decreases in intensity after a few months of storage under fluorescent light (maybe in a supermarket) and even more so if the bottle is clear. Storage in the dark showed no significant effect on the colour.
The aromas in the rosé wine are also affected depending on how it is stored. The most important thing to preserve the aromas in the rosé wine is to keep the bottles in the dark.
Not surprisingly, the experiments show that storage at high temperature in a clear bottle and in a brightly lit room have much more impact on the aromas than low temperature and darkness.
