The packaging is the first sip
With sparkling wine, packaging is never just protection. It is part of the ritual of opening, and part of the story a brand tells before the customer has tasted anything at all. The sound the box makes as it gives way. The weight in your hands. The texture under your fingers. All of it is information about what the customer is holding — and all of it arrives before the first sip.
That is exactly why working with Kalos Penina was a particular kind of challenge for Mycopor: build packaging that survives shipping a glass bottle, and that feels as premium as the drink itself looks.
The challenge: protect the glass without cheapening the look
A sparkling wine bottle is one of the harder objects to ship. It is heavy, impact-sensitive, and under pressure. Two approaches dominate the market, and neither solves the problem on its own:
- Expanded polystyrene (styrofoam) and foam inserts absorb impact well, but read as a cheap material that instantly undercuts a premium product — and they linger in the environment for centuries.
- Laminated cardboard packaging can look beautiful, but under real transport loads it often cannot protect the bottle without additional plastic inserts.
The brief was therefore simple to state and hard to execute: one single solution that cushions impact, looks premium, and leaves no waste behind.
The solution: mycelium as a structural material
Mycelium is the root network of fungi — a dense web of fibres that binds and strengthens organic matter in nature. At Mycopor, we grow it on agricultural residue, where over a few days it fills the exact shape of a mould and binds the substrate into a solid, lightweight, shock-absorbing material. Once the part reaches the properties we need, we heat-treat it to stop growth, leaving a stable piece of packaging shaped to one specific bottle.
For Kalos Penina, the result was a bottle-specific insert that wraps the glass along its full length and absorbs impact energy on its behalf. No additional plastic spacers, no air pillows, no film.
What the packaging delivers
Because the packaging grows to the bottle’s exact shape, it provides protection on its own — no extra inserts, void fill, or air pillows. The natural sand-toned texture reads as handmade, and the material is fully biodegradable, so the customer has nothing to separate or sort. It is also remarkably light, which shows up directly in shipping costs and transport emissions.
Design: details you feel, not just see
The box carries the Kalos Penina logo as a relief formed directly in the mould, not as a label or a surface print. The logo is part of the material itself rather than a layer on top of it — a detail a customer only notices once the packaging is in their hands, which is precisely why it works.
Each piece also carries a slightly different texture pattern, a consequence of a biological growth process. In a world of mass production, that small inconsistency is an asset: it signals exactly what a handmade sparkling wine signals.
Unboxing as part of the brand experience
Premium drink brands increasingly treat packaging as the first point of contact with the product rather than the last step in logistics. In that context, mycelium offers something printed cardboard cannot: a multi-sensory experience. The material is warm to the touch, matte, without gloss, quiet as it opens. It behaves more like an object than a wrapper.
The practical consequence is that this kind of packaging gets photographed and shared. Unboxing content is one of the strongest organic reach channels for premium drinks, and mycelium is visually unusual enough to earn attention without additional media spend.
Sustainability that needs no explanation
Every box is fully biodegradable. After use, it does not become waste — it simply returns to the natural cycle, breaking down in a home compost or a garden bed, with no industrial composting facility and no special sorting required.
That difference matters. Most “eco” packaging asks something of the customer: separate the layers, remove the plastic window, take the material to a specific collection point. With mycelium packaging, the only step is putting it in the compost. Fewer instructions mean more material actually disposed of correctly.
For brands that communicate sustainability, this is also a credibility question: packaging is the most tangible proof of the promise printed on the label.
What this means for premium drinks brands
For Kalos Penina, the packaging reinforces the story of a premium, handcrafted sparkling wine — material, process and result all tell the same story as the contents of the bottle.
For Mycopor, the project is further proof that mycelium can produce protective packaging that is functional, sustainable and visually on par with luxury goods. Sustainability and prestige are not a trade-off; they can be the same material.
Mycelium packaging makes particular sense for:
- wineries, sparkling wines and premium spirits,
- gift sets and limited editions,
- cosmetics and skincare packaged in glass,
- electronics and other high-value fragile goods,
- any brand looking to leave Styrofoam behind without losing protection.
