in my previous video about the london
coffee festival i did say there wasn't
much interesting but that doesn't mean
there was nothing interesting now in
amongst the festival there were a couple
of things that i wanted to know more
about one of those was the new project
from maxwell kalana - word called peak
water now this is a water treatment jug
similar to kind of Brita water filters
designed specifically for coffee and
that's kind of a big deal because in
London there's not much in the way of a
good solution I won't go too much into
detail about why water chemistry is
important I would probably recommend
checking out Maxwell's book and and
listing some of the talks he's given out
there none of the home filter solutions
like the British dart cartridges have
really done what's necessary to turn
very hard water into good water for
coffee and Maxwell's project has a
pretty cool solution to that and I'm
very excited to see it come to market in
the next six months or so I'll hand it
over to Maxwell I'll let him explain a
little bit more and I'll see you after
this quick interview
so the idea was wooden it'd be really
cool if we could get industry water
filtration technology and maybe tweak it
a bit make it a bit better make it based
on what we've learned but ultimately if
we could get it into a water jug this
really rudimentary thing that lots of
people have in their homes around the
world and we can make it adjustable and
it can make their coffee taste better
that's the idea what they do is yeah
thank to me
Everett sir I describe a typical
non-protected villager as like a
pour-over
for water yeah it's just imagine like
v60 full of a mix of some carbon and an
ion exchange presence yeah then all the
water passes through that and hopefully
their carbon does some work on it and so
does the resin and you get a fixed
results yeah so it doesn't matter which
water you put in it's going to act on
all the waters the same yeah you'll get
a different result with the water you
put in so the problem we have is a
really hard water needs more treatments
and a softer water but even though most
companies who produce drugs produce much
more sophisticated versions for cafes
the versions for people's homes are a
very simple approach
[Music]
and for my own personal frustration the
whole beginning of the water project was
recognizing it wasn't even recognizing
it was going okay so we've got a problem
our coffee doesn't taste how we want it
to yeah the person who wrote this coffee
doesn't think it tastes how it should
either yeah we both tested our waters we
tested the TDS is they kind of the same
that was the beginning why why don't
they taste the same
and actually the TDS doesn't really tell
us what's in the water it just tells us
there's something there what we've done
is people get a little test get nice and
simple and we'll tell them how to set it
now if they are really into coffee and
they want to go on piste
and they want to adjust it to their
preference up to them too but ultimately
or just the alkalinity and then we've
basically separated the treatment into
three chambers so we've got the carbon
which you mentioned before it's going to
get rid of things like chlorine or kind
of compound anything we don't really
want everybody a kind of agrees you need
carbon yeah so all the water goes
through the carbon and we've created
these maze systems we're calling baffles
or filter maze systems all these
different things and it means that all
the water is forced to to find its way
through all of the carbon before it gets
out the other side the problem with it's
a bit like you know on a pour-over you
would have channeling you have that same
problem with a water filter there's a
lot the water doesn't actually get
treated right
but then the hardness is going to be
dealt with by the second chamber and the
third chamber which will have two
different resins in so the way resins
work is they swap things around right so
you charge these little tiny beads that
look we've got some in here you can just
see them inside they're really really
small like sand almost they get charged
with ions and they swap with ion in the
water if you want cations you can only
do those yeah that's why we need the two
different resins one for an iron from
one cations in simple terms one to focus
on things like calcium magnesium yeah
and one to focus on things like nitrates
and sulfates yes yeah
so and we're still debating what this
represents and what this represents
don't think we'd have this for us
offsetting water and this for a heart we
may add more settings the coffee
community is very good at giving data so
lots people around the world when we ask
them to tested their water and told us
what kind of water they had there will
be an upper limit on this nobody quite
rightly from Mexico said are we can't
drink our water in Mexico get where
where I am can we use this jug and the
answer is no it's the clean drinking
water right to optimize it got me right
yeah and also at the higher level we
haven't said it yet but I would say that
once you start going about 800 parts per
million no matter what we do we're gonna
have a struggle yeah so there'll be an
upper limit on it and then what a lot of
people quite rightly ask is how was the
life of the filter and in the community
people are used to having a different
life based on the water but people at
their homes so ultimately at the moment
is quite an analog device so we were
adding all these things in like little
testers a digital display and the price
was going up and up and up but we really
wanted to make it accessible price-wise
so we tried to focus on the core
principles and it's quite analogue so
you would need to test your water and
then a booklet will say okay you can get
a hundred liters out of this yeah and
then it's kind of up to the user to be
aware of that hundred liters I think
people have probably quite surprised how
quickly they'll taste one of those has
done that's the other thing you get used
to it right yeah
like once you start drinking
well-prepared water and then you notice
your filter runs out like this copy just
doesn't taste oh it's the water right
and a little like a people they're
surprised they start to notice it
without knowing that they're noticing it
yeah yeah but the other thing that's
interesting which we have to tell people
is these systems all of us for it
they're BWC are see they're all open to
the air or it's in a cafe that system
seal right so the life is literally when
the filter can't do its job anymore but
with these there's a freshness element
priorities for those EU regulations
around the images to do a bacterial
build-up yeah so we have to tell people
to change them at two months regardless
of youth yeah is that like a legal
requirement we've got 27 days left okay
I've never done the Kickstarter before
talking to you yesterday was very useful
I found have some new things we can
start doing today yeah but yeah spoke
people who've done it and there's lots
you know there's the rules
30 days seems to be
yeah you know and getting most of the
money through the door that the first
couple of days so with three days in and
with 67% funded
congratulations thank you very much and
then obviously yeah we if we raise more
money great we can make more drugs and
hopefully get there quicker obviously if
we don't hit the target we don't get
anything yeah
but the money is for the tooling gotcha
there's always the painful part yeah I
think I didn't even really recognize
what tooling costs it's a lot of money
the coffee giving it is that are very
they it's kind of easy to get them
excited by and they understand the
challenges I think yeah yeah why when
are you hoping to deliver know them yeah
it's pretty good for Kickstarter six
months yeah that's pretty good
oh we've got after so what we've got now
is filters that work yeah
we're deciding exactly on the resins and
we would like to get it faster right now
it takes about eight minutes yeah we
think and that's on the setting we were
treating really hard right maximum yeah
right Sony's time exactly yeah so the if
you set it harder or we tell you to some
car or whatever and you use all the
mazes
you've snow that time right now but we
would like to be maximal about five
minutes oh and just quickly Safa can I
talk about soft water yeah so um lots of
people have asked questions about soft
water and the truth is the primary
design behind this was treating what I
was with the problem water
yeah moderate to high water on the plate
side soft water is still a problem water
just less of a problem yes people who
live in
anywhere around the world bits of water
I've been quite receptive to adding
minerals to their water whether they
follow the barista hassle concentration
or whatever and the idea is that with
the disks they're interchangeable and
once we launch this which we think is
solving the biggest problem yeah
we then intend to look at the second
disc Thank You moon rising awesome yeah
that's very cool congratulations thank
you very much if you want to know more
then right now
Maxwell's Kickstarter is live I think
it's pretty much funded so if you want
to get involved now is a good time I'll
leave a link in the description down
below you can get behind it I look
forward to seeing it come to market in
about six months from now so that was
one of the things that I thought was
pretty cool
at the London coffee festival this year
you
