Costs. These types of machines are generally free refills. You take a 32oz coke, and say actual cost to the store for you getting that coke is about 15 cents. You paid $2.30. Most people get 1 refill. But even if you get multiple, they still make profit.
I don't know wholesale costs of monster, but I know a 20oz bottle in stores here costs about $2. While a 24oz can of monster costs about $9.
It wouldn't surprise me if a 32oz fountain of monster cost the store like $0.70 wholesale. So there's no way they could make profit if people got multiple refills.
Plus, if you try to sell the monster at a higher cost than coke, what would stop someone from dumping the coke, and refilling with monster? Paying the lower innitial price, and now getting refills.
If you can get ahold of it, yes, very cheap. The problem is that a little goes a very long way, so it's not so easy to get a hold of anymore, at least in the US.
It was probably 10 years ago that I discovered that I could buy a 500g bag of pure caffeine powder for about $20, plus a milligram scale for another $20. I was drinking quite a bit of sugar free Red Bull at the time, and had been ordering them by the case ($50ish?) to save a little money, so it was a no brainer for me to switch to caffeine powder. Break even point was maybe 2 weeks worth of caffeinated beverages.
The bad news is a few people OD'd on caffeine powder around that time (completely unrelated to me), so it was pretty much banned. The good news is that 500g is a fucking shit load of caffeine. I often get my caffeine from more traditional sources now (coffee, tea), so that bag may end up lasting me the rest of my life.
For some additional context, a 250mL (8.4 oz) can of Red Bull contains 80mg caffeine, while a 1/16 teaspoon (~0.3mL) scoop of pure caffeine powder is about 200mg. That works out to less than 0.5¢ ($0.005) of caffeine per Red Bull, and I'm not even getting wholesale pricing.
Plus, if you try to sell the monster at a higher cost than coke, what would stop someone from dumping the coke, and refilling with monster? Paying the lower innitial price, and now getting refills.
People have been doing that for years with buying water, and then filling it with fountain drinks.
I suppose you could counter it the same way that some stores handled the soda refill issue. Have the energy drink refills behind the counter, where only employees can refill it. Have a special cup so employees can tell which customers actually bought an energy drink. Also gives employees a chance to intervene if someone tries to get too much and kill themselves (like with the Panera Bread lemonade/
Monster costs the company pennies more to make it. They just aggressively marketed these if they had a higher price because the original one in the USA, Redbull, was imported from Ireland at first which made the entry price higher.
Bars usually have redbull dispensers around here. But as others have mentioned, caffeine in bulk can do damage. I once went to a gas station and they had energy drinks on tap. I'm had a 48oz energy drink with energy shots. I TALKED WITH CAPS LOCK ON FOR 4 DAYS NON-STOP.
Out of sheer idiocy I grabbed a can of a new energy drink and it had 300mg if caffeine. I normally drink 500ml of tea a day but that thing had me vibrating through walls 50% into the can.
The inevitable howling from Karens when their children get ahold of a 64 ounce Big Gulp of the stuff notwithstanding, the main issue is that fountain availability would pull back the curtain on the supposed value of energy drinks. These are no more expensive than Coke or Pepsi or Sprite for their bottlers to produce, but they've successfully bamboozled the public into believing that a Monster or a Red Bull or whatever is "worth" 4-6x more per ounce than a normal soda. This is obviously bullshit, but if you were able to dispense it at the same rate and the same price as normal soda the jig would be up and the energy drink brands, not to mention the convenience stores selling most of them, would have an absolute cow.
What do you think would happen if you offered huge drinks, unlimited amounts or large capacity drinks of caffeinated, or energy supplements in a machine. What do you think a bored teenager with a bunch of his friends on a Friday night would do? They'd try to drink five gallons of Monster Energy just to see what would happen.
Someone would suffer a heart attack or some medical emergency and lawyers would have a field day milking concerned parents and restaurants with access to millions in insurance.
There at least used to be, and I got royally screwed by it.
The employee hooked the wrong "orange" syrup up to the dispenser, and what I thought was 32oz of Orange Crush (caffeine free) was 32oz of some Orange energy drink. Needless to say, I was up all night and ended up having to call off work the next day because I was so exhausted and useless (I'm very sensitive to caffeine).
Probably also less common due to liability. Panera got into hot water with their highly caffeinated lemonade.
I still maintain that someone with that level of caffeine sensitivity should have either:
1 - Read the fucking sign that said it was caffeinated, or
2 - Not drank a mystery liquid in lieu of signage
"but why would you think lemonade would be caffeinated?"
People with severe food allergies don't just shove random food in their mouths, why would this person?
My guess has a few factors to it (in no particular order):
Cost soda syrup is likely a lot cheaper than the chemical concoction for energy drinks.
Safety Energy drinks pose a much greater health risk if the concentrations are off. Companies would have to prevent young children from accessing the machines (if they are used in restaurants). They would also have to prevent customers from drinking too much. I can also imagine chugging a bunch of the syrup would likely kill you (it's bound to happen).
Flavor Control soda companies already accept and plan for the difference in fountain vs bottled sodas. I feel energy drink companies want as much control as possible to keep their brand image perfect.
Don't know about where you live, but in the EU, there's a hard upper limit on the caffeine concentration in drinks you can legally sell.
Any syrup designed to be watered down before you drink it would be above the limit and therefore illegal.
I've had postmix based energy drink in the Netherlands, so that's not true. Ingredients are not held to the same standards as premixed drinks.
To answer op's question, I think it's more of a supply/demand case, and a postmix doesn't display the brand as well as a can of an energy drink does (which is also marketing).
As much as i do consume energy drinks with a meal i do think we shouldn’t normalize it to much.
Also in a “restaurant” the strong flavor can be said to ruin the taste of the food. Though of course in practice we aren't going to these placed for fine dinning and often
precisely to get a chemical fix the places themselves still like to uphold some perception of being cullinary.
In addition to what everyone else is saying, a really good reason not to have energy drinks on a soda fountain, aside from the fact that the energy drink soda would cost far more than a regular soda, is that energy drinks contain a lot of caffeine and if they were on dispenser some idiot would go and fill up a 64 Oz energy drink and drink the equivalent to 5 to 8 Red bulls in a single sitting.
No gas station wants to deal with the legal ramifications of "exploding people's hearts because they are too stupid to understand that these things can be deadly", because if people are dumb enough to chug Red Bull until they die they are also dumb enough to sue because of the deaths.
Those machines are usually all plastic, acid doesn't hurt them. And a lot of the acidity in energy drinks comes from the carbonic acid in the carbonated water and the citric acid that's added. But those are present in a lot of sodas as well. They all have the carbonated water and a lot of them have citric acid as well. Something like Fanta is probably more acidic than most energy drinks.
The whole energy drinks are super bad because they are so acidic is mostly nonsense. The same was said about coke as far back as I can remember (and I'm an old man). Sure it's very acidic, but lots of things we eat and drink are acidic, that's something most of us can handle just fine. A lot of people think orange juice is a healthy drink, but it's usually more acidic than soda and unless you squeeze the fruit yourself usually contains just as much if not more sugar.
Not to say energy drinks are good for you, the combination of sugar and stimulants such as caffeine and taurine is most definitely not good. But the same can be said of many things we consume. Our bodies like a lot of the things that aren't exactly good for you. I've seen old folk complain about young folk drinking energy drink, whilst they themselves are drinking coffee with two sugars. When consumed in moderation energy drinks are totally fine.
For those who don't realize this, it's highly likely you will feel 1000 times better than you do today, in ways you may not expect, if you switch to drinking water.
I encourage everyone to try it for a month. And if you feel like a month is too long, evaluate your attitudes towards these things as it relates to addiction.
