Update on Chlorophyll extraction

Tarragon gin infusion before sous-vide infusion at 65ºC.

Not a lot of posts these days - I know.

I am trying to keep a bit more busy on Instagram - I have heard, that people are far more active on this platform...

And I have been quite busy anyway (yeah, I know: as always).

Now - I have to admit something: while my tarragon infusion worked perfectly at home (color-wise) - it has been not really successful on work. The aromas of tarragon were all there - but you have had (again) this faint light yellowish green.

Not good enough.

It seems though, that I found the culprit: too low alcohol! Even at 47% abc Bombay Sapphire isn't strong enough. When I used alcohol which has been around 70% it worked like a charm.

In the first hour (room temp) the alcohol slowly turned in a light green (but a more "unnatural" green with less yellowish hints). Heating it up to 65ºC It turned within another hour darker - but afterwards adding it into an ice bath, made it vibrant green.

Well - I have to admit, that the mint infusion has been more vivid green, but this is maybe also due to the type of herb.

So yes - I can now say the project has been completed: I achieved a green which is usually not achieved by any home-craft - and I haven't seen another bar achieving this.

Please come to Noir at the Kempinski and find out...

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
