Micro granulated cork stoppers

Description

Following the strategy of continuous innovation and development that is part of Amorim Cork’s DNA, the state-of-the-art Xpür® and Qork® micro-granulated stoppers were launched.

Ideal for preserving the wine’s freshness and intrinsic quality over time, Xpür® and Qork® facilitate extraction and offer the highest percentage of cork of all micro-granulated stoppers: 98% cork (by volume) or 82% (by weight), with no need to use microspheres.

This controlled chemical load guarantees a higher sensorial neutrality and a more positive wine evolution in bottle.

Delivering non-detectable TCA performance*, while keeping cork’s physical mechanical features intact, these stoppers boast the best CO2 balance of any micro-granulated stopper.

Functional, accessible and with impeccable sustainability credentials, Xpür® and Qork® bring perfect consistency and maximum quality

CORKING CONDITIONS

Ensure any dust its removed before corking.
Ensure the cork is compressed smoothly, to a diameter no less than 15,5 mm.
Ensure insertion of the cork is a quick as possible.
For standard bottlenecks, the cork should be inserted to 1 mm below the top of the neck.
Minimise moisture on the inside of the bottleneck.
Headspace should be at least 15 mm at 20oC.
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.
