Where would I get a small amount of Magnesium Chloride to brew with.

Walmart, Health Food Store?

There's not as much information here as I would like (such as whether it is considered food grade), but this site includes a link to a source where you can purchase magnesium chloride flakes: http://www.ancient-minerals.com/products/magnesium-bath-salts/

If your LHBS does not carry it, Northern Brewer had a small pouch for $1-2 or so a couple yrs ago.

edit> Actually that was Magnesium sulfate not chloride.

Magnesium sulfate also known as epson salts at your local drug store or grocery store

Obviously they are two different things. Epsom salts (magnesium sulfate) is available at any drugstore. Magnesium chloride appears to be much harder to find.

Why do you want to use magnesium chloride?

There are times (admittedly rare but possible) you might want to adjust the water by adding both magnesium and chloride rather than magnesium and sulfate. Magnesium chloride, if it were more easily available, would provide this ability. Some water adjustment software applications, for example, Martin Brungard's Bru'n Water, are programmed to calculate additions of this salt. I modified John Palmer's water spreadsheet to allow the same functionality.

Do a Google search for Magnesium Chloride and you might find it at a health food store near you.

One guy in our club gets it from a chemical supply company that he deals with, but he is a chemistry teacher and gets his class supplies from there.

I thought about using this for some beers, to get the Mg up without the SO4. Might be good for a Bo-Pils. The guy mentioned above does this for some of his beers, and he was a pro-brewer some time back.

Yes, exactly...a way to increase the Magnesium content and still have control over the Sulphate and Chloride additions.

In today's security climate it's almost impossible for individuals to buy chemicals that are not commonly used for home maintenance, in the kitchen or as health supplements. It might be worth making the acquaintance of a chemistry teacher who would let you have small quantities of some of these harder to find water salts.

At 2.2 lbs. (1 kg), that should be a lifetime supply for brewing water adjustment.

Again, it would be nice to know if it's food grade. The label says "for external use only."
