Why are red wine bottles recessed at the bottom

The biggest purpose of red wine bottle recesses is to accumulate sediment within the wine. This was crucial to winemakers in the early days of wine production when low temperature crystallization was not available. Using the bottom of the bottle at the groove to allow sediment and tannin crystallization to settle in the red wine bottle upright so that the sediment falls to the bottom of the bottle at the groove to reduce the impurities within the fine wine liquid.

Generally speaking, the longer the wine needs to be stored, the deeper the dimples will be. The presence of the dimples also makes it easier to hold the bottle in place during the mellowing process. Related to this, the presence of dimples also makes it easier to turn the bottle. The grooves also prevent the bottle from exploding. Fluted bottles are very secure, with the curve of the pit making the bottom of the bottle as strong as the walls, with champagne bottles having the deepest hollows.

For the characteristics of bottles that most wine lovers can name First of all, let's look at the color of wine bottles. As early as the 17th century, the color of wine bottles showed green, which was limited by the bottle-making process at that time, the bottles contained many impurities, so the bottles showed green.

Later, it was discovered that dark green bottles helped protect the wine from light and helped it age, so most wine bottles were made dark green. For white and rosé wines, they are usually put in transparent wine bottles in the hope of showing the colors of white and rosé wines to consumers, which can give people a more refreshing feeling.
