What Are Wine Bottle Cap Sizes

Different types of alcohol have their own unique charms, from mellow whiskey to pure vodka to elegant red wine, each of which occupies an important position in wine culture. As part of the wine packaging, the wine bottle cap size varies depending on the type of wine.

Whiskey bottle cap size

As a popular spirit, whiskey has various packaging forms and the bottle cap size is not completely uniform. In the market, there are many specifications for common whiskey bottle cap sizes. Some whiskey bottles use a cap with a diameter of about 35mm, which is a common size.

For example, some whiskey packaging uses a solid wood cap with a cork, and the cap diameter is mostly 35mm. The cork part plays a good sealing role to prevent the wine from volatilizing and maintain the flavor of the whiskey.

Some whiskeys also use a 28mm diameter aluminum ROPP cap, which has good anti-theft and sealing properties and is widely used in various spirits packaging, including whiskey. Different brands and series of whiskeys will innovate in whiskey bottle top design in order to highlight their own characteristics, but the common sizes are basically concentrated in the range of 28mm - 35mm.

Vodka bottle cap size

Vodka is known for its pure taste, and its bottle cap size also has certain characteristics. Generally speaking, the diameter of common vodka bottle caps is about 28mm, such as some aluminum ROPP bottle caps, which are widely used on vodka bottles. This size can fit the bottle mouth of vodka bottles well, ensuring good sealing, so that vodka can maintain its original quality during storage.

In addition, through actual measurement, the diameter of the bottle cap of the common 550ml vodka is about 32mm, and the height is about 13mm. This is also a more common vodka bottle cap size specification. Different brands of vodka may vary in bottle design, but the bottle cap size mostly fluctuates around this range.

Red wine bottle cap size

Red wine packaging is relatively more traditional and elegant, and its bottle cap size also has standard specifications. Generally, the diameter of the mouth of a red wine bottle is about 18.5 mm, and the diameter of the cork that matches it is usually about 2 cm, with an outer diameter of 28 mm as the standard mouth. The diameter of ordinary red wine bottle corks is mostly 21 mm, 22 mm, and the length is about 45-46 mm.

The diameter of the mouth of a red wine bottle varies according to the design of different wineries or bottles, but the diameter of most red wine bottles is about 18-19 mm. This size is designed to ensure that the cork can tightly seal the bottle mouth to prevent excessive oxygen from entering the bottle, affecting the taste and quality of the red wine, and also facilitate consumers to use conventional corkscrews to open the bottle.

In addition to corks, some red wines also use aluminum bottle caps. Aluminum bottle caps also occupy a certain market share in red wine packaging due to their good sealing performance, fine production technology, and the ability to present exquisite patterns through advanced printing technology.

Usually, the outer diameter of the aluminum bottle cap for red wine is about 28mm, which is compatible with the mouth of the red wine bottle and can achieve the sealing function well. The thickness of the aluminum bottle cap is generally between 0.20mm and 0.23mm. This thickness range can ensure that the bottle cap has a certain strength and is not easy to break or crease when processed on the automated production line, but it will not be too thick to affect the cost and the coordination of the overall packaging.

At the same time, the height of the aluminum bottle cap will vary depending on different design styles. The common height is about 15mm-20mm. The specific value depends on the shape of the top of the bottle cap and the design elements such as the sealing structure.

In actual production, different wineries or brands may fine-tune the size of the aluminum bottle cap according to their own product positioning and design requirements, but generally fluctuate around the above common size range to ensure that it can meet the requirements of red wine packaging for sealing and aesthetics, and can ensure production efficiency and product quality in large-scale production.
