Types of Wine Bottle Closures
When it comes to wine bottle closures, there are many different types of options to choose from.aluminum wine bottle closures Whether you’re picking up a bottle of Pinot Noir for Tuesday night or a sparkling Champagne to celebrate your birthday, chances are you’ll be perusing the store aisles looking for a closure that suits your taste and bottle. From natural corks to metal crowns, it can be a challenge to determine which type of wine bottle closure will work best for your needs. Here are some things to keep in mind when considering the various types of wine bottle closures:
Screw Caps
Also known as aluminum caps, screw closures can be printed with designs to offer unique brand enhancement and offer a sleek finish for bottles.aluminum wine bottle closures These specialized wine closures can be long-skirted and come in several liners for different bottleneck designs, closure situations, and pressure situations. These non-refillable, metal screw caps are a favorite amongst winemakers due to their consistency in oxygen interaction with wines and elimination of TCA taint.
Corks
Natural corks are made from a type of tree bark with special properties that make it an excellent material for wine bottle closures.aluminum wine bottle closures Its lenticels allow for an airtight seal, and the material is resilient enough to handle the pressure of a tightly capped bottle. It’s also durable, allowing for years of storage.
However, there are some drawbacks to corks that can affect the taste and quality of a bottle.aluminum wine bottle closures Corks can absorb aromas and flavors from other substances such as smoke, fungus and mold, chemicals, or even plastics. These off-odors can negatively affect a wine’s flavor and can be difficult to eliminate.
One advantage to using natural corks is that they’re an environmentally-friendly material. The wood used to create a natural cork is harvested sustainably, so the production of a single cork can result in the planting of multiple trees. Corks are also reusable and biodegradable, making them a sustainable option for wine bottle closures.
Unlike cork, synthetic wine bottle closures are made from polyethylene (which is derived from oil), meaning they’re not renewable or biodegradable. They can also be difficult to open, and some can be impossible to reseal after removal. In addition, some wine professionals claim that oil-based plastic corks can leave off-odors in wines.
Colmated Cork Closures
Agglomerated wine bottle closures are made from cork granulates, which are offcuts from the cork-punching process. These granulates are mixed with food-grade glue and formed into a block that can be cut to the appropriate size for a wine bottle. These wine bottle closures are typically used for still wines that will be consumed early, and they’re often covered with a decorative foil. They’re an affordable alternative to natural corks for wines that will be consumed quickly.
