Dried orange and lemon peel colour a compound gin as they flavour it, and nothing is redistilled to take it back out. Why that is normal and not a fault.
Infusing changes flavour, not alcohol, so homemade gin is the same strength as the vodka it was made from. Where to read the ABV and what really changes it.
Gin's flavour comes from juniper and botanicals, not the spirit, so a neutral vodka is the right canvas. Which bottle to buy, what size, and why not to overspend.
Colour changing gin is a plain gin infused with dried blue pea flowers. Nothing artificial is added, and the pigment shifts from blue to pink with an acidic mixer.
Compound gin steeps juniper and botanicals in a finished spirit instead of redistilling them, which is why it carries colour and why you can make it at home.
Making gin at home needs no licence, but selling it needs one from your council under the Licensing Act 2003, and producing for sale needs HMRC approval.
No licence or HMRC approval is needed to steep botanicals in a spirit you have bought. Producing alcohol and selling it are the two things that do need permission.
Infusing botanicals into shop bought vodka is legal and needs no licence. Distilling your own spirit without HMRC approval is an offence. Here is where the line sits.
Bottled colour changing gin keeps up to a year, and the kit 18 months from packing. Why light, not time, is what fades blue pea flowers and the finished bottle.
