Agglomerated cork stoppers

Description

Spark® Agglo.Cost effectiveness for fast turnaround bubblies.

Agglomerated sparkling cork stoppers offer excellent consistency and reliability, providing a resilient and airtight seal that preserves the wine’s effervescence and quality.

The uniform structure of these stoppers is prepared to withstand the pressure generated by the carbonation within the bottle. In addition to their functional benefits, agglomerated sparkling stoppers also contribute to the overall presentation and sensorial experience of the wine. The natural appearance of cork adds a touch of elegance and tradition to the bottle.

This combination provides the ideal balance between performance, cost, traditional experience, and eco-friendliness, making them perfect for fast-rotation sparkling wines.

Don’t leave the cork stoppers in the feeder as to avoid dust.
Always use stoppers with a surface treatment suitable for the type of beverage, bottling process and selected bottle.
A vacuum must be created in order to prevent internal pressures.
