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

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
