Avoid storage bottles and containers made of plastic when you store your flavoured schnapps and liqueurs.
Plastic-lined lids and caps - and bottles with rubber rings - are no good either.
That's because the flavours from plastic and rubber could be transferred to your schnapps or liqueur and spoil it.
Glass, steel, ceramics, and glazed earthenware are fine materials for storage. So are used spirit or wine bottles with screw-on tops - as long as they are absolutely clean and without any residual flavours.
If you choose to use coloured glass bottles, make sure they are made from dyed glass.
Painted glass bottles are no good, because the paint will adversely affect your infusion.
Some times the paint will even peel off.
Close your storage bottle or container with a screw cap, tight-fitting lid...
...or wine cork to prevent oxidation that will otherwise give a flat, stale taste to your infusion.
If you want to use corks to close your bottles, use new wine corks of good quality.
Because a wine cork is cylindrical it will fit perfectly into the bottle neck and prevent oxidation.
Old or used corks might not fit properly, they can impart an off taste, or they can crumble from age.
Wine corks can be purchased at any wine-making or brewers supply store.
Remember to label your storage bottles and containers with information, such as...
Also, keeping a log with other valuable information is very helpful, especially if you are experimenting with your infusions.
