Glass bottle for organic kombucha

Cans are environmentally friendly, my ass!

Many kombucha brands advertise with the light and uncomplicated packaging in the form of a can. We find a real Kombucha lover drinks the tea drink from the glass bottle. It's not only emotionally driven, but it's also healthier for you and your environment in many ways. We have summarized for you why we think kombucha belongs in a glass bottle and not in an aluminum can.

1. i want to see living kombucha and not just taste it

In most cases, the fermented tea drink isn't just drunk because it's super refreshing and delicious. It contributes to a healthier life and most importantly supports the gut in the form of the many live cultures and nutrients.

The can completely disguises the tea drink and its live cultures. If you don't have a glass handy at the time, you drink the kombucha from the can without any idea of the color and current state of the drink. If proper refrigeration was neglected it may have continued to ferment and small mini cultures may have formed. In an opaque can, this can lead to an unpleasant surprise in the form of a slippery culture in your mouth. In a glass bottle, you would have discovered this long ago.

Kombucha should be protected from UV rays and is therefore often bottled in brown glass bottles. Since we store our bottles in opaque boxes and then refrigerate it directly at our distributors, our bottles are sufficiently protected.

Of course, we reject Kombucha in plastic bottles, because the various organic acids formed by the tea fungus can react not only with metal, but also plastic and contaminate the Kombucha.

2. aluminium cans are coated with plastic from the inside - in most cases this contains BPA.

Cans should be protected from corrosion so that no metals can dissolve and get into the liquid of the can. This could change the taste and colour of the drink. For this reason, the surface of a can is covered with an epoxy plastic in the form of a thin film. This material almost always contains bisphenol-A (BPA).

Various independent scientists and environmental organizations have been warning about the harmful effects of BPA on the human body and its hormones for quite some time. Scientists also question a safe dose of the chemical, as is often argued.

It makes one think that even with a low concentration of BPA, when kombucha is consumed regularly from a can, the concentration of the chemical can end up adding up virtually uncontrollably.

High acidity, like that found in kombucha, intensifies BPA's penetration. According to Consumers Union, "In early January 2015, the European Food Safety Authority announced a provisional new intake limit for bisphenol A. The limit is considered safe for daily consumption. The daily intake level considered safe was lowered from 50 micrograms per kilogram of body weight to 4 micrograms per kilogram of body weight."

3. How harmful is a can really to the environment?

The can has slowly made its way back onto supermarket shelves and cafes after a long hiatus. The image seems to have been properly polished up. Various retailers advertise with slogans such as that of the Association of Can Manufacturers that a can has a "recycling rate of 99 percent" and that its light weight compared to a glass bottle "saves CO² during transport". If you take a closer look at the processes, it quickly becomes clear that the recycled cans do not really always become new cans.

Only 50 to 70 percent of the recycled material is used for new cans, but not without the necessary 30 to 50 percent of new aluminium being added.Conversely, the fewer cans that are produced, the less new aluminium is needed.

In addition, there is the high amount of energy needed to produce aluminum cans. In addition, the can has a comparatively high recycling cost in the form of a multi-stage process.

What particularly prevents us from filling cans is the fact that primeval forests and rainforests are cut down in various countries such as Brazil or Indonesia for the mining of bauxite, the basic material for aluminium. We cannot reconcile this with our organic product. The glass bottle is still one of the heaviest in comparison to others during transport and has an increased CO² balance there, but in the meantime the proportion of waste glass shards in glass bottles is up to 83 percent and according to the latest technology only about 150 ml of water per bottle is used for cleaning.
