Vetropack develops UV-protective transparent bottle for Corsican brewer Pietra

Vetropack has developed a transparent glass bottle with functional UV protection for Brasserie Pietra's Limoncella beer, a Corsican white beer introduced in 2025. The bottle is made at Vetropack Straza in Croatia using feeder colouring, in which UV-protective frits are added to colourless base glass in the feeder rather than in the melting tank. It is the first bottle Pietra has had custom-made for one of its beers.

Why this mattersThe project shows glassmakers using feeder colouring to offer brand-differentiating clear bottles with functional UV protection, a niche capability for smaller beverage customers.

• Vetropack Straza in Croatia manufactures the transparent UV-protective bottle for Pietra Limoncella, a beer introduced in 2025
• The bottle uses feeder colouring, with UV-protective frits added to colourless base glass, leaving a slightly greenish tinge where the glass is thicker at the base
• It is the first custom-designed bottle Brasserie Pietra has used for one of its beers
• Vetropack Straza holds the widest range of glass colours in the group and runs smaller batches of special and UV-protective colours through feeder colouring
• Brasserie Pietra was founded in 1996 in Furiani, near Bastia in Corsica, and employs almost 50 people
