At the risk of being pedantic this is not a question of physics but one of chemistry.

I received a Gin Making Kit last Christmas. Instructions: Buy a bottle of vodka ... I kid you not!
I am reliably informed that all gin is vodka infused with botanicals. It's just that proper gin makers produce their own rather than nipping down to Tesco to stock up on Smirnoff

Vodka is, after all, just diluted alcohol. The quality of any vodka is only a measure of how thoroughly every other impurity is removed.

Apologies for the literary reference, but to quote Charles Dickens for a moment,

”This sausage is mouldy, Fagin.”

”Shut up and drink your gin!”

Isn't chemistry just a subset of physics?

Chemistry is applied Physics
In turn, Biology is applied Chemistry
I guess any number of subjects could be described as applied biology...

Although it really really pains me to say, physics is applied maths

Ice contains impurities. Bubbles form on the nuclei of impurities. So ice = bubbles. Impurities can also be just rough bits. Which is why Grolsh glasses have the word Grolsh embossed inside the glass at the bottom to make the beer fizz more.

There is a distillery in Breckenridge, Colorado that makes some very fine sprits - particularly whiskeys. I took a tour a while back (handily, they had a shuttle to/from where we were staying as the tasting portion was quite generous ). While they ferment, distill, and age their whiskey locally, they buy the alcohol for their Vodka and Gin from someplace near Denver and have it shipped up in huge vats where they combine it with local spring water and (in the case of gin) the appropriate botanicals then bottle it. They claim the local spring water accounts for a significant portion of their flavor profile (same for their whiskey).
I asked if the altitude and climate contributed to the flavor profile of their whiskeys (the distillery is at ~9,600 ft.) - I was told not really, and unfortunately results in a significantly greater loss to the 'angels share'.

I worked for a small bottling company in Stainer Street SE1. Proper Vodka and proper gin is distilled in specific ways (I also worked for Beefeater Gin). You can get cheap vodka and gin which is made from Ethanol and flavoured with gin or vodka (yes you can get vodka flavouring).
We also put caramel in cheap whiskey (distilled correctly but often lost it's colour during filtering) to colour it. For Russia we just bottled the Ethanol straight.

Specific grain recipes in the mash do affect the taste of the resultant alcohol - higher end whiskeys have grain recipes that are closely guarded secrets (some even have very specific yeasts that they use) so naturally vodka and gin can be affected by the grain recipe. There are also specific flavor profiles associated with the type of still used (pot stills vs. reflux stills - with countless variations of both) to distill the spirts (although I readily admit that the specifics of why the still type matters is beyond my knowledge base).
All that being said, a lot of these subtle flavor differences are probably beyond the abilities of most people to detect. A while back I developed a taste for Bombay Sapphire Gin. But I soon discovered that I couldn't readily tell the difference between Bombay Sapphire and the Costco Kirkland brand London dry gin - which was considerably cheaper. I know purists will likely sneer at that, but if I can't tell the difference (and the price difference is massive - especially if I buy the Costco stuff when I'm in Colorado it's ~1/3rd what I have to pay for Bombay in Washington.
BTW, what's wrong with the taste of ginger? I'm quite fond of a gin Moscow Mule (basically Gin, fresh lime juice, and ginger beer) (btw, despite the name, Moscow Mule is very much an American creation). I've usually fine with a gin and tonic (at least if it's made with decent gin), but like I said I need to watch my sugar intake and tonic water has nearly as much sugar as Coke (and all the sugar free tonic I've tried have sucked). OTOH there are some food sugar free ginger ales readily available - and I can even get sugar free ginger beer concentrate to make Moscow Mules.

Henry's law is in reference to the partial pressure of the gas above the liquid and the amount of dissolved gas in the liquid; the higher the pressure the more gas will be dissolved. A capped soda bottle is under pressure, in the range of 17 psig; when the bottle is opened the pressure is reduced to 0 and the absorbed CO2 will seek a new balance because of the reduced pressure and hence will foam. To quote Mr. Henry (thanks Wikipedia)
… water takes up, of gas condensed by one, two, or more additional atmospheres, a quantity which, ordinarily compressed, would be equal to twice, thrice, &c. the volume absorbed under the common pressure of the atmosphere.
Lowering the temperature allows more gas to be dissolved; this is why a room temperature soda, when opened, will foam more than a chilled one. I should know, I'm a U.S. TTB Certified Wine Chemist (really).

Edited to add: A few years ago I got a great idea for a sparkling wine. Why not use nitrous oxide as the dissolved gas instead of CO2? I did some calculations on solubility and it was possible to dissolve quite a good amount of gas. My thought was that the consumer would pop the cork, pour a glass, and take a deep sniff, getting a good hit of laughing gas in the process. Jolly times indeed, alcohol and laughing gas! Of course there might be a bit of push back from the Feds......

Clean ice, gin, slice of lemming, tonic as you like
Personally, I prefer a slice of squirrel in mine, but to each their own.

Right!
Now boys and girls, sit down and SHUT UP!!!
After 30yrs of making G&T also known as Mothers Ruin... Here is how to make a perfect G&T.
I have always used Gordons - so one assumes that it doesn't matter which one you use. But you MUST use Schweppes Indian Tonic in those small 300ml bottles (no plastic, and not that low calorie rubbish!).
Ok, here we go.

1) Chilled Glass.
2) A few ice cubes.
3) Slice of Lemon, slightly crushed with your finger tips to produce some juice and a bit of loose pulp.
4) Pour Gin in over the above mixture.
5 Pour Tonic Water to brim.

It should be 'effervesecing' and maybe some lemon pulp at the surface.

You can all thank me later...

These physics are all well and good, buuut, so far, nobody has mentioned the most complex...extracting the wallet and payment therein...which is why the best G n T is the one somebody buys for you

Vodka has now been mentioned. Tried some real Russian vodka, once ! and the gyro's toppled shortly after the intake but it has occurred to me since with that stuff sloshing around your bloodstream it's no wonder they all seem immune to -30C and below.

Never a vodka fan, but, as anybody who enjoyed a Gov't paid holiday in Germany will confirm, the stuff was liberally added to screen wash in winter.

Thumbs up G & T

Recently bought a still and installed it in the garage.

First product was gin and have never stopped making it.

We now have a range of colorful gins in the cupboard and each one is as good as you can get over the shelf.

After starting with gin I have since tried making different whiskey's, brandy + some fancy liqueurs, all of which have been well reviewed by the family and anyone who cares to try.

After about a year the still has well and truly paid for itself because we have never had to purchase over the shelf liquor products.
