Yes.

Is that okay, you ready?

Yes it is.

All right, great.

Firsthand question from @bennyfactor, on Twitter,

asks, "Do you prefer San Pellegrino or Perrier

"or some other sparkling mineral water

"that we've never heard of?"

@bennyfactor, on Twitter,

asks what kind of sparkling water do I prefer.

Well, in fact, benny, the answer is quite complex.

It differs according to my mood.

I can tell you this.

If I am drinking sparkling water on it's own,

I might prefer San Pellegrino,

which is an Italian sparkling water.

I like San Pellegrino under that circumstance.

I could tell you that my favorite sparkling water

to drink after espresso is the German Gerolsteiner water,

which is quite a freak of nature.

The mineral content is so incredibly high,

over 2,000 parts per million total dissolved solids,

also known as TDS and the mineral content is so high,

in fact, that if you were to drink a Liter of it a day

you would have a quarter

of your daily requirement of magnesium.

And magnesium is a very difficult mineral to obtain.

Supplementing orally is inefficient.

I rub magnesium lotion all over my body

to make use of transdermal absorption.

People don't understand; sometimes they use

artificial products that they rub on their skin,

like certain sunscreens and lotions and they say,

"It's okay, I'm not eating it, it's on my skin",

but whatever you put on your skin

goes into your bloodstream.

For example, people wearing nicotine patch

and other medication patches for a

very direct absorption to the bloodstream.

For example, cavemen used to swim in the ocean all the time

and the ocean is a rich source of magnesium.

That transdermal exposure

gave the cavemen the magnesium they needed.

Now swimming in the ocean has fallen out of favor

for most of us and therefore other methods are necessary.

Organ meats have also fallen out of favor,

another rich dietary source of magnesium.

Nevertheless, Gerolsteiner, to me,

has such a dense minerality that perfectly suits

the bitter complexity that you get

from drinking an espresso.

Wow, okay, do you just get it from the internet.?

The great thing about Gerolsteiner

is it's so readily available.

It can be found at every Trader Joe's store

that I've been to.

It can be found at Whole Foods.

I think it costs $1.49 at Trader Joe, $1.69 at whole foods.

Oh my God.

However, if you buy a case of Gerolsteiner water

at Whole Foods they give you anunadvertised

10% case discount, bringing the price down

17 cents per Liter.
