Jeffrey Morgenthaler‘s new experiment - mostly correct...

After quite some time, Jeffrey Morgenthaler posted an interesting article. 

It is all about size and cloudy vs. clear ice cubes. But Jeffrey didn’t completely nailed it. And there is even more of a problem, because his article might put some bartenders on the wrong path. Why? Well he compared smaller ice cubes vs. a slightly bigger ice cube versus super clear ice cubes.

Please read the article...

Now here are the fallacies and ”quasi-fallacies”:

- Biggest fallacy is, that he referred to the difference of the melted water to the original temperature. That is total nonsense. The energy which is needed to raise the temperature of ice is negligible to the energy which is needed to melt ice. This means 4° difference is impossible to make any reasonable difference in melted water!

- Jeffrey is also referring to the cloudiness to air bubbles in the ice - which is not necessarily completely wrong (air can be frozen into ice, if not frozen one-directional) - but most of the cloudiness comes from the refraction of light as a ice cube which is frozen the traditional way is breaking in itself (ice is expanding - but as the outside is freezing before the inside, it will result into fractures in the ice).

Does it make a difference? Not necessarily. But especially the first point could lead people to think, that the size and shape of ice cubes doesn’t matter a lot - but while this might be true for ice cubes out of the freezer, it is not applicable for ice cubes which are at their normal state- at 0°C.

Because dilution is also highly influenced by surface water of the cube - and here it matters: shape and size of the ice cube.

The big super clear ice cube had one more advantage against Jeffreys favorite cube: it was taller and was not fully submerged. Melting depends also on the medium (liquid vs. air).

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

"Monin Rocks!" - Really?

R ussell S anchez MONIN UAE MONIN Rocks @ HARD ROCK CAFE Dubai  — with   Rhiandro Gardiner  and Louie Aquias  at  Hard Rock Cafe . I have seen this on my Facebook timeline. And well... I wanted to write about Monin since quite a long time, but haven't. However this message was a catalyst, to speak up. It is already a couple of months ago, that I routinely checked the ingredient list of a Monin bottle. ...and was shocked.... Point is, that I have always defended Monin against my US colleagues as decent brand. At least with the products they offered here in the Middle East and in Europe; they came from their factory in France. Most of the ingredients [except lets say in Blue Curacao syrup] were natural. Long time ago, somebody from Monin explained, that this is due to the quite strict regulations in France for syrup - there it is a family culture to drink syrup sweetened water/seltzer. And off course especially for the k

What is the best cranberry juice in the bar?

A good friend of me "whatsapp'ed" me today and asked for my expertise: "What is the best cranberry juice?" I would loved to just let him know the brand - however it is not that easy. What do we understand of cranberry juice? One of the biggest [maybe the  biggest producer] of cranberry products is Ocean Spray. And: it is well regarded. Problem is: it is not a juice! Wait - what? Ocean Spray doesn't produce a juice - they produce a juice cocktail - which translates into a lot of water, a lot of sugar, some taste-balancers as citric acid [nothing against this really] and a minuscule portion of juice - usually around 3%. Yes they have something which is called 100% juice. Which is on one hand true, on the other the biggest deception ever. Because you don't get 100% cranberry - you get a mixture of juices of concentrate - most of the time apple and white grape and a bit of cranberry. There are also some other brands around, which might feature a h
