Plastic - If in doubt leave it out
Conventional wisdom

says that plastics are generally a bad idea.
Some materials are designed for such use and can generally be trusted for short term contact. Other materials, such as the Britta system, are clearly not intended for use with solvent liquids like ethanol.
Of course there are 'some' plastic type materials that are useable and used with alcohol, you can buy Whisky in plastic bottles in some countries. However, unless a container comes with 40%ABV or above alcohol in it or has a label from a reputable manufacturer saying "Safe to use with high strength Ethanol/alcohol" it's safer for distillers like us to assume it's not suitable for such use.
The reason plastics are generally said to be unsuitable, for use with ethanol, is the fact that most people have no way of
definitively identifying which plastics are safe to use with a serious solvent substance, such as ethanol.
It's not as if there are no alternatives
Ethanol, at any strength, is not a food substance, it has quite strong solvent properties and should always be handled and treated as such
Common Sense says if you're not completely certain don't do it.
