When it comes to wine glass bottle sealing - which is better: corks or aluminum screw caps? If you say corks are better, you are wrong. The truth is, the worldwide demand for wine aluminum screw caps is growing, hence you need to get familiar with the future of wine preservation. Take a closer look at why aluminum caps alternatives are better in terms of their ability to store and age wine. Take a preview of this alternative to wine storage to get you thinking about where the wine world is going. Aluminum screw caps were introduced to wineries around the 1950s-1960s (approx.). However, they’ve rapidly become a large share of the market today. If you ever travel to wine-making western countries like New Zealand, Australia, South Africa, Chile, etc, you’ll notice that screw caps are on nearly every single wine bottle in the country. Additionally, screw caps and closures have also gained popularity among consumers in North America, Latin America, Europe, Asia-Pacific, Middle East &...

A bottle closure is, simply stated, as a device that seals the contents inside of a bottle. It protects the contents from dust, spilling, evaporation, and/or from the atmosphere itself. The finish and closure are interrelated entities of any bottle. The closure must conform to the finish in order to function, and vice versa. During the early 19th century (approximately) there was only limited demand for glass bottles & jars since most goods were sold in bulk by general stores out of barrels, pottery jugs, wooden boxes, burlap sacks, and the like. Most people also lived off the land and had limited need for glass bottles; they also lacked the resources to pay for such luxuries. Thus, the incentive to develop varying closures was limited as cork sufficed for virtually all of the bottled products of the time. The use of glass bottles - and the need for varied closures to seal them - arose with an expanding city-based market and even then for just a few types of bottled goods - pri...

With consumers more educated and mindful about what they put in their bodies, ensuring product integrity has become of prime importance for the food and beverage sector. Consumer attitudes — along with growing market trends around transparency, sustainability and ocean-safe products, and specialty and premium goods — have presented strong opportunities for glass containers. Storing goods in glass containers eventually become popular because glass is made from natural elements. Unlike cans, drink boxes, pouches, and other food and beverage packaging, glass bottles/ glass containers are the only packaging that doesn’t require a plastic or chemical liner that may affect the stored content. It's a pure product with a natural barrier against toxins, making it suitable for consumables in the food and beverages industries. Sterilization procedures during the bottling of beverages are essential, and glass bottles usually stand up well to high temperatures. Moreover, glass bottles/ glas...

The dark truth of the wine trade is that one in twenty bottles of wine is ruined as soon as it is bottled with the cork. The topmost problem is the ‘cork taint’. This is when a wine takes on a musty odor caused by a chemical called 2,4,6-trichloroanisole (TCA) that is present in some corks. TCA itself is produced by microbes that live in the small pores, called lenticels, that run throughout the cork bark. In extreme cases it’s hard to miss a ‘corked’ wine: the mustiness can sometimes be overpowering. In other situations, the taint is a little subtle, as a result, the fruitiness of the wine is reduced, giving it a subdued aroma. In the past, many people weren’t as aware of the problem and happily drank corked wine. But with the increasing awareness, consumers have decided that they’re not going to put up with this situation any longer. For now, then, the leading contender to cork is aluminum screwcaps and closures. Aluminum screwcaps and closures provide a pretty good seal—better...
