Locking in the flavour of oils and vinegars
Every year hundreds of millions of extra virgin olive oil and balsamic vinegar bottles using aluminium closures leave their country of origin in as perfect condition as when the precious liquid was bottled. Whether large manufacturers or small specialist producers they rely on aluminium closures to guarantee the quality of their products.
And these closures can enhance the consumer experience in other ways. So, in the case of olive oils, recent developments have seen pop-up pouring devices to control pouring speed, dosage and reduce product wastage through dripping. Also they can eliminate the risk of the bottle being refilled with a different, lower quality product, protecting the integrity of a brand as well as the consumer.
