Adding a water tap

How about Polish vodka? The Poles (not surprisingly) claim it's far better than Russian. The 'mainstream' Polish brand is Wyborowa, the one I quite like is 'Zubrowka' (Bison brand, with a blade of grass in it).

So you're doing this in the UK? If so, you might find things changed a year ago:

Have a look at the second paragraph of 3.7.1 here:

This type of thing works, for a little-used pipe, but it does obstruct the pipe somewhat, which may be a problem for whatever is downstream.

Do you have a cold feed to a washing machine or similar nearby which could be teed?

An outside tap kit would do what you want - and more - you wouldn't need all the bits.

The simplest solution is probably onne of these:

Freeze distillation.

I know that you've been offered different solutions but I'm sure that there must be an adapter you can fit to the tap after unscrewing the filter. There's dozens of different ones on Amazon.

Only removes the water but leaves all the lower and higher alcohols (methanol, propanol, butanol etc) in the fluid, which are not good for you and anyway taste foul (apparently).

Best way to distil alcohol is with a fractionating column with a thermometer in the top, and discard all the stuff that comes over first, until the thermometer reads the boiling point of ethanol,78.2°C, and stop collecting the distillate when the thermometer starts to rise again, above 78.2°C.

If you have a mixer tap this might work.

What happens to the bits of copper created by making the hole? Do they come out backwards with the thread?

Laboratory tap is a good point to start searching for taps you can easily fit small tubing to.

I'm not sure there are any because I think it part-punches a hole (with the flap left in situ) rather than cutting it.

I only suggested it because the OP seemed to want something which didn't require any plumbing skills. Personally, I'd cut the pipe and fit a proper tee.

The notice does say it's intended for commercial producers and I'm - thankfully - not in the UK.

Could be interesting; many thanks.

F*ck arsing around under a kitchen sink ain't no fun. I'm not averse to picking up a blowlamp when needs must, but I'd sooner be in and out of there with minimal delay; hence the request for a quick and simple solution.

Looks interesting. I had no idea there were such things. Wonder if they're all standard threads......?

Methanol is the stuff that makes you go blind and there shouldn't be more than a trace of it if any in commercially produced spirits. I would imagine that discarding the 'top' (the first distillate to carry over) would result in a very insipid product at the end of the process. I suspect that's the bit with all the flavour in it!

A couple of budgets ago there was a change in the way duty on alcoholic drinks is calculated. It is now charged according to the strength of the alcohol contend. If you increase the strength of an alcoholic drink, then theoretically you should pay additional duty.

That said, if you are reprocessing a product on which duty has been paid and reprocess it in your own home for your own consumption, how would anyone know?

.. and the volume.

The amount of alcohol should not increase.

According to a former colleague, an emergency plumber removes them from the kitchen tap washer on Christmas day.

Surely that's a swarf fairy?
