Glass Bottle Manufacturing Since 1985.
As a glass wine bottle factory, we often see a wide range of wine bottle colours, from light green, to colourless and transparent, to brown, and some are blue, these different colours are not by chance, but carefully chosen. Is it to attract consumers' attention, or is it to avoid light for storage? There's a lot more to this wine bottle colour story.
1. Why is green the most common colour for wine bottles?
Back in the 17th and 18th centuries, when wine bottles first began to appear, green was the most authentic "true colour" of wine bottles. At that time, due to the limitations of glassmaking technology, glass products were naturally green, and it was impossible to make colourless and transparent glass bottles. The raw materials used for glass production (sand, limestone, etc.) contained impurities containing iron compounds, and the technology at that time was not able to remove these impurities, which was the root cause of the green colour of the glass products at that time.
2. Why are white and rosé wines often bottled in transparent glass?
Transparent glass bottles give people a feeling of freshness and transparency and can show wines in front of consumers at a glance. Transparent glass bottles are a sign of the progress of modern production technology, but these kinds of glass bottles will only be used for wines to be consumed within one to two years after bottling, or else the wines will be oxidised very easily. Therefore, if you need to keep your wine for a long time, you will mostly put it in a coloured glass bottle. However, it does not mean that wines in coloured glass bottles are always suitable for preservation.
3、What is the function of coloured wine bottles?
Wine deteriorates easily when exposed to bright light because the ultraviolet rays in the light can penetrate the glass and accelerate the oxidation of wine. For this reason, wineries often choose dark-coloured bottles in order to minimise the effects of UV rays on their wines. For example, wines from the Moselle region are often bottled in green Hocker bottles, while wines from the Rhine region are often bottled in brown Hocker bottles. Coloured wine bottles also provide protection against light and temperature changes, preventing deterioration and damage to the red wine. With reasonably designed necks and corks, red wine bottles are able to maintain the freshness and flavour of the wine, allowing each drop of wine to age quietly in the bottle, waiting to be enjoyed by the taster.
As a professional glass packaging bottle provider, our predecessor was a state-owned enterprise established in 1985, and set up our own international business in 2004.
