Wine Bottling Process You Need To Know

The process of bottling wine is quite similar to bottling beer, though there are some key differences due to the unique requirements of wine bottles, which vary in volume and shape. Traditionally, wine bottles are sealed with a cork, and out of cork is a shrink cap,and the process is designed to ensure that the wine remains in excellent condition until it reaches the consumer.

Wine Bottle Cleaning

Wine bottle cleaning is a crucial step in the wine production process that ensures the quality and longevity of the final product. Cleaning is an integral part of this process, as it prevents contamination and ensures that the wine remains pure and free from any unwanted microorganisms or residues.

In wine bottling, various specialized equipment is used for cleaning to ensure the quality and safety of the product. Automatic bottle rinsers, which can rinse multiple bottles simultaneously with water or sanitizing solutions, are commonly used in larger operations. For smaller operations, manual bottle rinsers, including handheld devices or small-scale machines, are more suitable.

Sterilization is a crucial step, and this can be achieved using steam sterilizers, which use steam to eliminate contaminants, or chemical sterilizers that utilize solutions such as peracetic acid or sulfur dioxide. Cleaning tanks are also essential, as they provide a space for soaking and cleaning bottles and equipment with various cleaning agents.

To ensure bottles are free from any residues, bottle washers use high-pressure water jets and brushes for thorough cleaning. After washing and rinsing, air blowers and dryers are used to blow filtered air, effectively drying the bottles and preventing moisture from affecting the wine quality.

Conveyor systems play a vital role in transporting bottles through different cleaning stages efficiently, ensuring consistency and streamlining the process. Additionally, CIP (Clean-In-Place) systems are employed to clean the interior surfaces of pipelines, vessels, and other process equipment without the need for disassembly. These systems use a combination of cleaning agents, water, and sanitizing solutions to maintain cleanliness.

The Filling and Corking

First, the wine is filled into the bottles. After filling, each bottle moves to a machine called a corker. The corker compresses a cork and pushes it into the neck of the bottle. This step is crucial because it ensures the bottle is properly sealed. During this corking process, the machine also vacuums the air out of the bottle. This creates a negative pressure headspace inside the bottle, meaning there is less air inside the bottle than outside. Removing the air, and therefore oxygen, is important because oxygen can oxidize the wine, which can spoil its flavor and quality. Additionally, the negative pressure helps counteract any pressure changes due to the wine’s thermal expansion, which can happen if the bottle is exposed to temperature changes. This prevents the cork from being forced out of the bottle.

For sparkling wines and champagnes, there is an extra step. After corking, these bottles are sealed with a muselet, which is a wire cage that fits over the cork. The muselet ensures that the cork does not pop off during transportation, which could happen due to the pressure from the carbonation in these types of wines.

Labeling and Packaging

Some modern bottling lines use alternative closures, like screw caps, which are becoming increasingly popular due to their convenience and reliability.

In addition to corking, many bottling lines have other quality control features. For example, a fill height detector checks each bottle to ensure it is filled to the correct level. If a bottle is underfilled or overfilled, it is rejected. Some lines also include a metal detector to ensure that no metal contaminants are present in the wine.

Once the bottles are filled and corked, the next step is to apply a capsule to the neck of the bottle. These capsules are usually made of plastic or tin and are applied using a machine called a capsular. This capsule adds an extra layer of protection to the cork and gives the bottle a finished appearance.

After the capsule is applied, the bottle moves to a labeling machine. Here, a label is affixed to the bottle, providing important information about the wine, such as its origin, type, and vintage.

Finally, the bottles are packed into boxes and moved to a warehouse where they are stored until they are ready to be shipped to retailers or directly to consumers.
