Clinistix, sugar meters and sugar
TAMSNJ
sugar correspond to the colors on the test?
How about a diabetic's blood sugar test meter? Can this be used to test for
sugar? How do I translate from the meter reading to % sugar in the wine?
Sorry if these questions are too simple for this group. Thanks to those that
respond.

troll!
I would ask no one else to respond and I am sorry for posting myself!
It make me so cross! I mean really what a load of rubbish ( my spelling is

The poster wants to know how to test the residual sugar in wine. A standard
way of doing is to use the Clinitest kit that was used for testing sugar in
urine for diabetes.Works fine for wine too.
I don't know about clinistix, but I do know that the blood sugar meters
won't work because they only respond to glucose levels and wine sugars are
a mix of glucose, sucrose, fructose and others.

There is no "Ummmm" about it!
Clinistix are notoriously inaccurate in giving a real assessment of sugar
levels in urine! I know because I have used them. They are a cheap and
useless ( ie very inaccurate) method of detecting sugar in urine.
This is a case of someone pussyfooting about and has nothing to do with
winemaking at all.
The statement ----"Sorry if these questions are too simple for this group."
is a sure sign that the respondent is just stirring. And it has stirred me!
I suggest the poster readdresses his/her post to a diabetic newsgroup where
an appropriate answer might be expected.
Hot on here

Not sure what set Trevor off. But in the winemaking circles, it's the
Clinitest tablets that are typically used for RS sugar determination.
Never heard of anyone using the stix or a meter. But if the meter
reads percent sugar, that's close to degrees Brix.
Many winemaking shops here in the states will sell not only the
tablets, but an interpretation guide too. They now come in individual
foil packs that are more than just convienent:

Note, these are only used for measuring trace levels of sugar (< 1%).

I'm really not sure what you're concerned about. The use of Clintest
tablets is standard practice in winemaking for testing residual sugar in
wine. A logical follow on question is whether Clinistix and meters and
serve the same purpose - they can't as far as I know.
His question is about WINE not about diabetes, and is perfectly valid.
I don't know your situation or why this bothers you, and I'm sorry it does,
but it is a valid winemaking question.

Wow, now that's a subtle troll.
For someone to sit down and think, hmm, given that Clinistix are notoriously
inaccurate, why don't I go to some discussion group that has nothing to do
with diabetes, and ask about measuring sugar levels with Clinistix, because
I'll bet I'll run into a diabetic that has had a bad experience with them
there, and it will really, really piss them off.
Good catch, Trevor. I would have missed it completely. ;-)

Apologies, but Clinitest tablets by Bayer are used in North America to
spot check residual sugar in wine and are still manufactured in
Illinois. I understand they are not considered useful by most doctors
over here either with the advent of inexpensive glucometers. I often
think the only people that keep this line running are winemakers. I
work for a large medication wholesaler and we still stock them to
supply on special order to pharmacies, but no one seems to keep them
in stock for the above mentioned reason.
Original poster:
Clinitest tablets are used to measure Residual Sugar (RS) in wine.
Winemakers do not use glucometers or 'sticks' as they have filters
applied to measure glucose only. Get the tablets from a winemaking
shop and an interpretation guide will come with it. You can measure
from 0.25% to 5% with a modified test.

response was unwarranted.
For that I apologise.
You see, the reason for my response was the, I quote, " Sorry if these
questions are too simple for this group."
To me it was a clear indication of what I call a "stirrer" or if you like a
troll!. I may be wrong and if so I make my apologies again ------- but the
original poster hasn't yet responded to any posts on this string.
I say, yet again, that the Clinistix available in UK, on prescription, for
Diabetics to test their "sugar levels" in urine, are extremely unreliable in
detecting variation in "blood sugars" and I would not imagine using my
"Accu-Check Active" meter to test my wine!!!!!!!!!!!!!!!!! I suspect that my
taste buds, on my tongue, would be better! However I do not drink wine that
has not been fermented to dryness --- others are offered to "wine
uneducated" guests ( and I do not mean that to be disparaging but wine
drinking is an acquired talent )
However, in any case, you will shortly have the happy event of my absence
from this NG for a couple of months. On Friday 26 March I leave home at
about 0900 hrs ( GMT ) to begin my cycling pilgrimage, 2000 km, on the road,
and camping, to Santiago de Compostela in Spain and I hope to celebrate my
67 birthday in Santiago. All by bicycle except from Portsmouth to St Malo
(in Brittany).
So I shall not be putting my foot in it again until about mid June!

It's takes a big heart to admit a mistake - I applaud you.
In addition, I wish you very well on your cycling tour. I wonder, have you
considered how best to attach a fermenting carboy of wine to your bike ;-)
Have a great time, and we'll enjoy having you back.

Hi Trevor,
For what it's worth, as a former chemist and continuing diabetic and
winemaker, I think that clinitabs, as opposed to clinistix, are very
useful for winemaking.
They're not nearly so useful for monitoring diabetic control of
blood sugar, but not, I don't think, for the reasons you give. They
actually do a fairly reasonable job of telling you how much reducing
sugar you have in any given solution, be it wine or urine, espcially
when used in conjunction with the modified color charts that you can
get over here (U.S.) for wine analysis.
The reason that they're not so useful for gauging diabetic control
is not they they don't acurately reflect the amount of reducing
sugar in solution, but that the amount of sugar in urine doesn't
tell you all that much about the amount of sugar in the bloodstream,
and THAT'S the number that tells you about diabetic control. This
is true for two reasons:
1. the amount of sugar in urine tells you what was going on with
sugar in the bloodstream about 2-3 hours ago. The amount of time is
variable, which is a problem, and knowing what was going on in the
past isn't nearly so useful as knowing what's going on NOW, and
2. the bloodsugar level at which people "spill" sugar into the
urine differs from person to person, so that even if urine sugar
told you what was going on at a given moment in the bloodstream,
which it can't and doesn't, it still wouldn't be well correlated
with absolute levels of sugar in the blood. That is, the normal
threshold for any sugar to appear in the urine is said to be about
180 mg/dL in the blood, but can be much lower for some people.
So anyway, clinitabs are useful for winemakers, but not so useful
for diabetics.
Dave
