Since joining here I have become very wary of how I store/transfer my spirit.
It is a real shame that most home brew shops and their still manufacturers dont highlight the risks. Bit irresponsible I reckon.
Anyway I have a few questions regarding the passing of spirit over various materials.
1. I always store my neutral in 5L glass demijohns (Ithink theyre called) but the all have a white rubber seal at the top. Is this a concern?
2. What about mixing the nuetral when using liquer essences? Plastic measuring jug and spoon a big no go?
3. Gaskets between easy flanges. Is EPDM rubber suitable or would silicone be a better option? I have been looking for natural cork but cant seem to find any that hasnt been reconstituted with some sort of glue. On the topic of silicone, could gaskets be made with the everyday neutral cure roof and gutter stuff or would the acetic cure anti fungal stuff be a better option? I know I can buy silicone gaskets but want to keep as much of the build as home made as possible.
I dont know if I am being over cautious but I plan on not having my spirit touch anything other than copper, stainless or glass. So I busy running around looking for stainless funnels & spoons and glass mixing jugs.
Any feedback would be greatly appreciated.
Cheers.
