For years, preserving and canning were seen as old-fashioned and alternative, but today, they are experiencing a true renaissance. Harvesting and preserving food—what could be better? Many are returning to their grandmother’s recipes, preparing sweet, sour, or savory treats to enjoy homemade delicacies that last.
Müller Glas offers a comprehensive selection of preserving jars: screw-top jam jars, clip-top pickle jars, round jars, square jars, hexagonal jars, and straight-sided jars—suitable for both cold and hot filling, airtight, and resistant to various contents.
With the myRex brand, we also offer a special canning line, including jars with the traditional Twist-Off closures as well as the more advanced GPI openings. Learn more about our myRex private label in our product category.
With the original Rex jars, we have been able to revive Austria's most iconic preserving jar. These timeless straight-sided jars are just as suitable for jam as they are for serving dishes in gastronomy. With its recent brand relaunch in a retro design, the Rex jar, with its 111-year-old history, has been making headlines again in the media.

Too Good to Waste – Cornelia and Andreas Diesenreiter Turn Surplus Fruits and Vegetables into Something Great
"Throwing away good fruit and vegetables? Not with us!" – This is the motto of Cornelia and Andreas Diesenreiter. Since 2016, the siblings have been producing high-quality gourmet food from surplus fruit and vegetables. Their range includes classics like grandma’s apricot jam, as well as trendy new creations like watermelon-pepper syrup.
Every year in Austria, thousands of tons of perfectly good fruits and vegetables go to waste in agriculture, simply because they do not meet market standards or cannot be sold profitably.
Unverschwendet has made it their mission to integrate as much surplus produce as possible into the value chain, preventing unnecessary food waste. Their growing popularity is driven by word-of-mouth recommendations from satisfied customers and enthusiastic farmers supplying their surplus crops.
