Wine packaging process: keg or bottle?

Although the most widespread wine packaging process is the one in glass bottles, the keg method is also becoming increasingly popular: in fact, the number of places where it is possible to taste wines on tap is growing, with a wide choice of quality products.

Another very interesting trend in recent years is wine in cans, especially for sparkling varieties, but not only: we will talk about it extensively in one of the next articles on this blog.

Tendentially, bottled wine is the one preferred because the bottle allows perfect aging over the years and consequently results in a flavor that greatly enhances the product, due to the perfect harmonization of all its components.

But how is wine bottled?

There are three main steps in wine bottling process:

  • rinsing: bottles are sanitized by rinsing with water or other disinfectant solutions;
  • filling: once sterilized, bottles are filled with wine, taking great care to keep the quality of the product intact;
  • corking: lastly, the process is concluded by capping the bottles.

However, the stainless steel keg also has its advantages, in fact:

  • is durable and safe;
  • is washable and reusable with a life cycle with no expiration date;
  • is perfectly capable of preserving all wine properties;

How does the wine brewing process take place?

With regard to keg filling, there is an initial preparation phase involving three main steps:

  • prewashing
  • washing
  • sterilization

Once this thorough washing cycle has been completed, the wine is packaged in stainless steel kegs, the best material from the point of view of hygienic safety.

Finally, Comac also offers machines for packaging wine in cans, a mode that is becoming increasingly popular, especially for sparkling wine.

In this way it is possible to provide customers not only with a wider and more versatile offer but also with a reliable one, thanks to the high technological level of these machines that thus ensure the perfect preservation of wine and all its characteristics.

Some of Comac successes for wine packaging

The great versatility and quality of the wine packaging lines have enabled Comac to gain great appreciation in Italy and around the world, receiving very positive feedback from our customers.

These include Free Flow Wines in 2020 and Casa Vinicola Zaramella in March 2022.

Free Flow Wines is a young Californian company founded with the goal of providing quality wine on tap, while also paying close attention to environmental sustainability.

Comac designed and built the perfect kegging line for their needs, equipped with two filling machines. The line includes a number of standard machines, but also customizations designed to the customer’s needs: for example, the separation of the two filling lines, which makes it possible to fill kegs with two different products at the same time and thus optimize production time.

Results have been excellent, managing to combine high production capacity with excellent wine quality.

Instead, the experience with Casa Vinicola Zaramella, headquartered in the province of Padua, dates back to the beginning of this year.

To meet its production needs, Zaramella chose to install a Comac VERONA K51 – 5 +1T line.

The production line proved to be efficient and left customers satisfied also thanks to the commitment, kindness and professionalism shown by the entire team involved in the project.
