Sodium vs. Potassium meta for sulphating cider

[Warthaug]

I know that sodium metabisulfate is generally considered interchangable with potassium metabisulfate for sanitizing wine equipment, but my question is are they interchangable for killing off the wild yeast in pressed cider? If so, do you use the same quantities?

I've found a number of cider instructions, but they all call for and provide measures for potassium metab. I have sodium metab and was hoping I could just use that.

Thanks

They are the same, except that the sodium metabisulfite contains sodium. You can use them interchangeably.

Excellent. Thanks!
