Agglomerated cork stoppers

Description

The Neutrocork® stopper is the latest in new-generation technical stoppers.

Its main feature is its great structural stability. This stopper is recommended for wines with a certain complexity, intended for early consumption.

Functional, accessible and with impeccable sustainability credentials – each stopper shows a balance of up to -392 g of CO2 – Neutrocork® is recommended for fast-rotation wines.

Neutrocork® offers great structural stability, resulting from a uniform-sized micro cork granule composition pressed into individual molds. With an attractive appearance and easy extraction, it is the choice of thousands of wineries around the world.

Bottling recommendations

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.
