Our sparkling wine corks are composed of two discs using solid natural corks and a body made from crafted micro-agglomerate cork. They are specifically designed to withstand high pressure and only use FDA approved food-grade glues. The agglomerate body also meets stringent visual requirements.
One-Plus-One technical corks are composed of sterilised agglomerated cork granules topped and tailed with high quality natural cork disks. Using only FDA‑approved food-grade bonding agents, these combined corks offer many of the attributes of our natural corks.
Our natural corks are 100% TCA free which ensures they won’t interfere with or taint your product. The combination of pleasing aesthetic and excellent performance means these natural corks are well suited to all types of wine and spirits.
Croxsons supplies micro-agglomerate corks. They are constructed from sterilised natural micro-granules that are uniform in size, excluding those which don’t meet narrow tolerances. As with all of our products, we only use FDA approved food-grade bonding agents. Micro-agglomerate corks are a cost-effective option that can help you to achieve the same high-quality standards as natural corks.
Our colmated corks are competitively priced to give our customers the option to maintain the look of a natural wine cork. The small pores of these natural corks are filled with cork powder to produce a more visually pleasing stopper. At Croxsons, we can supply FSC® certified products (FSC – C009204).
To ensure the highest quality cork, we collaborate with the best cork growers. The freshly harvested cork planks are filtered for superiority, cut into strips, hand-punched to maximise material use and then modified in design to ensure consistency. This process enables us to maintain complete control. All the excess material is ground up and used for agglomerate corks which means we are able to reduce waste and recycle what we use.
A Croxsons cork is always fully sanitised. By using a closed chamber system, the cork planks are boiled at 105°C under high pressure so that they receive prolonged pressurised steam. This process removes cork taint, off-aromas and tannins. Thanks to this rigorous process, our customers can rest assured that Croxsons corks are always neutral and benefit from improved appearance and elasticity.
Our system naturally washes the finished corks using ozone and hydrogen peroxide. This highly advanced process further reduces any organic impurities and off-flavours. With three different washing options – colouring the corks a natural, light brown or white appearance – the cleansing process ensures neutral flavour and consistent colour.
