Two figures in, a clear answer out. The sulfur calculator uses free sulfur dioxide (so₂) and wine ph to produce molecular sulfur in wine, applying the standard relationship for this problem in the order the calculation actually needs it.
What Is the Sulfur Calculator?
The sulfur calculator sorts out the arithmetic of free sulfur dioxide (so₂) and wine ph so that you can concentrate on the cooking rather than the maths.
It gives you molecular sulfur in wine, which is usually the number you actually need to measure out before you start.
How to Use the Sulfur
Fill in what you have and read off molecular sulfur in wine. If you are scaling a recipe up or down, work out the multiplier first and then multiply every quantity by it, including the ones that are not in this calculator.
Weigh rather than scoop wherever the recipe allows it. Volume measurements drift with how tightly an ingredient is packed, and that is where most recipe inconsistencies start.
Getting Consistent Results
Kitchen temperature, ingredient temperature and how long you mix all change the outcome. The calculator handles the quantities; the technique is still down to you.
If a result looks unfamiliar, check your units before you change the quantities. A factor of a hundred or a thousand is the usual culprit.
A Worked Example
Working through an example, with free sulfur dioxide (so₂) set to 10, wine ph set to 5, the calculator returns molecular sulfur in wine of 0.01. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out molecular sulfur in wine?
Enter free sulfur dioxide (so₂) and wine ph. The calculator then works through the relationship and reports molecular sulfur in wine.
What does the sulfur actually calculate?
It takes free sulfur dioxide (so₂) and wine ph and converts them into molecular sulfur in wine using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter free sulfur dioxide (so₂)?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Does anything you type get stored?
No. The whole calculation runs inside your browser, and nothing you enter is uploaded, logged or sent anywhere.
Do I have to fill in every field?
Only the fields a particular result depends on. If you leave one blank, the results that need it simply show a note instead of a number, and everything else still works.
