Is Magnesium the secret ingredient?

Water analysis, treatment, and mineral recipes for optimum taste and equipment health.

Hi all,

I was just looking at replacing my water filter cartridge and I noticed filters are available that add magnesium to the water for a more luxurious taste in tea and coffee.

See here for example: ... ality.aspx

Has anyone tried a side-by-side comparison of their normal water filter compared with one that adds magnesium? Can you taste the difference? Is it better?

Per Dr. Robert Pavlis, coffee beans have relatively high amount of magnesium and no positive value adding to the brew water. More here: Argument against magnesium sulphate?

A lot of the water recipes use Epsom salts to add magnesium, there's been lots of water tastings and articles discussing minerals added to water including magnesium. I sometimes add Epsom salts with the baking soda I add to my brew water, but for ours it's hard to say if it makes much difference.

The late, great Dr Pavlis was/is a definitive source regarding brewing water. There is also Jim Schulman's extensive and wonderful study found on this web site.

Thanks, I did a search but didn't find those links. I might give it a go and see if I can taste a difference.

We found that we enjoyed magnesium as sort of an 'accent mineral' in our taste testing. We have a ton more about water chemistry ... sory-data/ if you'd like a short read.

Thanks, Evan, for the interesting read.

Do you know of any plans to offer a water chemistry class at the Crown Royal in Oakland in the future?
