Using cutting edge technology in the bar - how to keep things warm

 It is the season. There are more events (yeah - events with people, pandemic is kinda mitigated - yay…), hot drinks are requested.

Before especially in events I have used “coffee urns” which kept warm with gel-stoves.


It works quite well, they don’t need a lot of space, they are also keeping things warm. But: you cannot really control the heat (its real fire). 

And beverages which are thicker (e.g. hot chocolate) start to burn. Also: if you are holding alcohol drinks warm, it will evaporate and overheat.


What is the solution:

Using a water-bath. A bain-marie is not exactly something new - only that the kitchen appliances usually take more “real-estate”, and the manual ones are not made for beverages (not deep enough - they are made only to hold food warm), and the electric ones are not only big - but they are also very expensive.

Enter Sous Vide, or better said an immersion circulator. If you are only heating a couple of bottles of a beverage, a wine bucket is already big enough to do the job. An immersion circulator is also far more affordable than you think. This technology has evolved and pretty much it democratized the use of advanced kitchen appliance. Sure, you the market leaders with fancy mobile apps, are still expensive (but even they seen “the light” and due to cheap competitors, they had to cut their prices significantly). But really you don’t need for basic bar tasks an immersion circulator with a mobile app. Good news: they are working all pretty well, independently from the price.


How to use an immersion circulator for hot drinks?


  • Use glass bottles!
    • I would suggest, that you are using glass bottles to pour your hot drink in! Vacuum bag are fine (you don’t necessarily need to seal them), but it is awkward to pour out of a bag.
    • Glass bottles tent to be very hot at this temperature. Get some gloves (water proof!). or at least some dry dish towels to handle the bottles.
    • Leave the top of the bottles out of the water - which also helps you to handle the drinks safely. 
  • Temperature range:
    • think about the temperature of your drink. 
    • 60ºC to 65ºC is usually hot enough
    • but if you are using room temp glasses and if it takes some time to serve the drinks (which is typical for events), 68ºC to 72ºC would be a far better range.
  • Depending on your immersion circulator: use heated water
    • If you have a relatively cheap and conveniently small immersion circulator, it might not be the most powerful appliance of the world. Hence Use directly warm or even hot water, to aid its work. Hence it just have to keep the water at the temp, without heating it up. This shortens the time of the heating process (of the water but also of the drinks).
  • Use not a big water container (Sous Vide)
    • Try to use the smallest container you can. Obviously the beverage bottles have to fit in. But the bigger the container, the more water has to be heated.
    • The less water, the better for the environment (water wastage, energy use).
    • The less water, the shorter the heating time of the immersion circulator.


And this is about it. It is an easy system, which uses contemporary technology. It let you shine, even though it makes your life far easier and the drinks more consistent and better.


And obviously you are not only using an immersion circulator for holding beverages hot. You can use it for homemade syrups, speed up infusions or even really more advanced stuff like fermenting* like amazake (*yes, it is not exactly fermenting - but rather an enzymatic conversion of starch to sugar).

How to use citric acid - and why you might not want to use it anyway!

To be honest, I shied away of this topic, because I think, people can misinterpret this - big time. I don't want to be part of the problem - I want to be part of the solution!  But when Chris, over at A Bar Above  discussed this subject- I literally could not resist to join into "the discussion". Here is the video: I - however take a bit slower approach than Chris. What is citric acid? Chemical Compound Citric acid is a weak organic acid with the formula C6H8O7. It is a natural preservative/conservative and is also used to add an acidic or sour taste to foods and drinks. Wikipedia Formula: C6H8O7 Molar Mass: 192.124 g/mol Melting Point: 153C Density: 1.66 g/cm3 Boiling point: 175C Soluble in: Water Why is it controversial? In my "mixology world" it is controversial, as citric acid is the stuff, which makes the nightmarish sour mix [ preferably in powder form ] sour. Yeah - citric acid is the main ingredient in one of the most

Agar-Agar Clarification

Not often, I am posting here things, which are clearly not my ideas... However Dave Arnold is clearly a mad scientist [no, he really is!] - and he posted amazing stuff on his website www.cookingissues.com - no - don't click now - just follow the link later. One of the most impressive posts about mixology, besides of demystifying the mechanics of shaking, were clarification techniques. Look, after him, you could use a centrifuge [which would set you back a couple thousand bucks] and a chemical compound, which solidifies sediments. I am not a fan of that. Then there is gelatine clarification; this works quite well [I tried it several times my self] - you gelatinize a liquid [with little gelatine only], freeze it, thaw it [in the fridge] over a colander and a muslin cloth. Thats it. Unfortunately this has several problems: Gelatine is made out of animal bones - hence it is neither vegetarian nor vegan, which you won't usually expect of a beverage. You have to freez

King Robert II Vodka

Who would knew, that I am reviewing a budget vodka here - on the opinionatedalchemist.com. But this isn't a normal review. I skip the marketing perception and use this product to cut directly to the case: Vodka is a "rather" neutral, colorless, "rather" flavorless and odorless distilled beverage from any agricultural source - and depending on the country, it has a minimum of 37.5% and 40% abv. As I said time and time again before: at times it is absolutely nonsense to talk about premium and luxury, when the original product doesn't really "hold this promise". Luxury water can have luxurious marketing, luxurious packaging, can be even rare and slightly more expensive "to produce". However really it is just water. Maybe it has some nuances to normal water - however those nuances (in a blind-test) are pretty small. Vodka is extremely similar - and the chain of evidence (despite a lot of people trying to proof otherwise) makes it re
