Handy Widget for Agar-Agar Clarification

I thought actually quite a few hours about the tricky parts of agar-agar clarification: the calculation of the variables: quantity of liquids, quantity of agar-agar, temperature of liquids...

And then I 'tried' to clarify pineapple juice and just made myself wrong: I wanted to clarify 0.75 liters - though then used [without valid reason] 1.5 liter juice without the adjustment of the agar - and the most stupid thing was, that I've only acknowledged my mistake, when the "to be clarified" juice was already in the ice water bath! Lame!

That is why I looked for a handy calculation widget, which I post here on my blog.
Unfortunately it was quite tough to find a proper tool.

I finally found editgrid.com, which is an amazing and simple tool, for just posting spreadsheets on blogs or on websites. It is not very elegant - however it works...

And with my embedded calculation, you will be able to just add the weight of the liquids and the temperatures and you will know, how much agar-agar you would need and if the temperatures are high enough.

To be able to use this tool [which is pretty simple] you need to know below points:

  • The two different liquids below are especially meant for clarification of heat sensible ingredients like juices. Either way, you can use just water for the 2nd liquid - or you can use half water, half juice for it. This 2nd liquid will be the heated liquid, which will be hydrating and dissolving the agar-agar.
  • If you would like to clarify a liquid which isn't heat sensitive, you can just use one liquid [and just put it into one cell].
  • Usually the main liquid is around 2 parts and the 2nd liquid is around 1 part.
  • To be accurate [and save] it is highly recommended to use a thermometer for the liquids and a scale for the weights.
  • The target temperature has to be above 36°C, to not prematurely jellify [which will result in a failed clarification].  To be anywhere near this target temperature you would need to keep the main liquid close to room temperature and the other liquid around the 80°C mark.
  • Please don't fill up a higher temperature than 100°C - as this is technically & physically pretty impossible. [and no - weisenheimer don't need to comment now, that anywhere below the mean sea level, water can boil at higher temperatures. This is anyway not practically].
  • Please don't even boil your liquid [just simmer], as the heat could destroy the ability of agar-agar to solidify.

Hope you can use and enjoy this little tool!



If you are editing - please have some patient - it takes few moments, until the form updates itself and shows you the agar-agar quantity, the target temperature and if it is too cold or adequate.

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 controversial [and in the modern craft bartending wor…

Is Jack Daniel's a Bourbon Whiskey?

So Jack Daniels want to make us believe, that it is not a bourbon - but it meets all standards of a bourbon - only it is better?!

Half of it is true: Jack Daniels meets all qualification points for a bourbon. And yes it is true, that they add one more step - the charcoal mellowing. However this doesn't make it not a bourbon.

Well - point is, that the question is not really adequate. The answers to the rather vague question: "Is Jack Daniels a Bourbon?" is driven by semantics and interpretations.

What you could ask is: Can Jack Daniels rightly be called bourbon?
And the answer is: yes, it can. It meets all points to be even a Straight Bourbon [however please note the differentiation to Kentucky Straight Bourbon - as this is again a regional denomination, which Jack Daniels obviously doesn't meet].
The video is explaining exactly the laws. Before Jack Daniels also stated very proud, that they are sour mash. This was a bit... misleading, as most American Straight Whisk…

Secrets of Darcy - this is the best way to create sugar syrup

I am a "rich syrup guy"... not a "simple syrup guy".
This is, because it is better to be able to control dilution by yourself - not by he setup you have got.

I had also a pretty straight forward method: adding 1 kg sugar into 1/2 liter of cold water and blend until dissolved (be carefully, not to blend too long with a high-performance blender, because it would heat up).

The issue here: it takes some time - because sugar doesn't "like" to dissolve in cold liquid.

A lot of bartenders are adding sugar into hot liquid. This isn't a good idea either: due to hydrolysis the sucrose is converting into fructose and glucose. This makes the sugar thicker and sweeter - but also makes the result less consistent (as you don't meticulously monitor all details (time, temperature, pH, etc.). Further the thickness of the glucose worsen the ability of the syrup to mix in cold liquid (speak a cocktail).
