Surface treatment for bar-top corks used for white spirits

One of the areas we specialise in here at CorkLink is making bar-top corks (also known as capsulated corks) for the spirits industry. Typically these corks are made with a much greater degree of customisation than wine corks, for several reasons:
– there is a wide variety of bottle sizes used in the spirits industry
– capsules can be made from different materials (plastic, wood, cork)
– capsules can be easily customised with different kinds of printing
– wooden capsules can be more easily customised for relatively small batches of just a few thousand corks

Here at CorkLink we have a broad range of clients sourcing their bar-top corks from us often for relatively short production runs, sometimes with very specific requirements for their corks. However, one of key areas that many clients are not aware of is the need to give corks destined for bottling white spirits a special surface treatment to avoid transferring any colour from the cork to the liquid – this surface treatment involves a process that both whitens the surface of the cork and fills any pores and we have developed a unique process to carry out this function.

We would also recommend that any client using natural cork for their white spirits should use a very high quality cork, as having fewer pores in the cork with help to further reduce the risk of any colouring the liquid, because a smooth cork is less prone to dispersing colour than an uneven one. For this reason we recommend that clients using natural cork for white spirits should use corks of quality “Super”. It is of course possible to use micro-agglomerated cork for this purpose, which are less likely to give up colour than natural corks, but you would also need to consider that micro-agglomerated corks are around 30% glue and you may prefer to use a 100% natural cork. Natural cork also helps to give a more premium, organic feel to the packaging.
