		Sodium and potassium meta are different - one contains sodium and the other potassium.
		Sodium meta is slightly more effective and slightly cheaper, but it has a bad rap because in general people want to lower their sodium intake.
		Sodium meta is stronger than potassium - 64% SO2 vs. 57%.

	SO2 by Ben Rotter @ Improved Winemaking (http://members.tripod.com/~BRotter/) (Site not responding. Last check: 2007-10-09)
		Thus, the SO2 content of sodium metabisulphite is 2 x 64.1/190.2 = 67.4% and that of potassium metabisulphite is 2 x 64.1/222.4 = 57.6%.
		Sulphur dioxide (in the metabisulphite form, or otherwise) is sensitive to high temperatures and humidity.
		However, consistency of the tablet size in manufacturing is questionable, and many winemakers claim there is little certainty that tablets contain the amount of metabisulphite they are intended to (figures have been seen to vary by up to at least 25%).

	March 2002 NEWSLETTER Vol
		Apart from the chemical formulae, there are a few reasons why potassium metabisulphite salts (KMBS) are used in winemaking instead of the cheaper sodium metabisulphite (sodium metabisulphite is still available for those wishing to use it as a form of sanitizer for equipment).
		Potassium metabisulphite has a higher sulphur content, and also keeps better, therefore making it a more efficient additive (sodium meta starts to smell like lye after exposure to air).
		The main reason sodium metabisulphite isn't used anymore, is that it may be risky to diabetics.

		Sodium MetabisulphATE does not work but as its only one letter different even chemical supply houses can make a mistake and send the wrong stuff.
		Sodium MetaBisulhite is used in home winemaking for sterilising bottles so you can buy small quantities at home brew shops.
		Just keep adding Sodium Metabisulphite and stirring it in with a glass rod gently until no more gold precipitates out.

		Choose the sulphite source by selecting either potassium metabisulphite or sodium metabisulphite from the drop-down list.
		Most winemakers use potassium metabisulphite for additions to wine, but sodium metabisulphite is often used in sanitizing solutions.
		In the previous example, it will require 0.66 g or 0.11 tsp to raise the SO2 level from 30 mg/L to 50 mg/L. This example assumes that potassium metabisulphite was used in powder form and added to a 5 U.S. gallon batch.
