SIGH!

So, here I am, trying to stabilize some wine.
I don't like using campden tablets as much,
though they're easy in terms of measuring.

I would like to know the equivalent measurement
for campden tablets in terms of TEASPOONS!!!!!!
1/4? 1/8? 1/2 of 1/8????

A lot of times I read about GRAMS!!!!!
Add so many grams...
How in the world are we supposed to measure GRAMS?!?!?!?!?
@#$%@$&^

Sorry, I'm just a little frustrated,
and have wasted an hour of research while my wine sits waiting to be
racked.
Is there a convenient resource anyone has to just check what might be
recommended
for those of us who enjoy easy volume as opposed to metric micro
measurements?

Thanks ;-)

Hi Rick,

That is truly confusing :-(

Yes, it can be.
if my post was confusing, I meant to say I like using the powder as
opposed to the campden tablets - - easier to dissolve,
but when a lot of info seems to talk about measuring in grams, and all
i have is teaspoons or 1/4 or 1/8 tsp., then needed to know the
conversion process!

Lum's link was helpful.

Thanks.

Wow....thanks, Lum.
Didn't find THAT article!
Appreciate the link and the info!

Rick

Be careful. That article has some mistakes. For instance if you try to use
his equation in the example given as

(30-10 + 5 for guess work) mg/L total. (5 ) (3.785)( 25) / (1000)(0.57)=
0.83 grams

you will not get the 0.83 grams he indicates, you will get 674 grams which
is a little much.

He is shooting for 30-10+5 mg/L so I take it that means 25 mg/L He then
multiplies this by the number of liters which is 5 * 3.785. So far so good.
then he multiplies this by 25. I do not know where that 25 comes from.
Then he divides by 1000 to convert to grams and then multiplies by 0.57 for
the percent. I think he meant to divide by 0.57. I think the equation
should have been:

(30-10 + 5 for guess work) mg/L total. (5 ) (3.785) / [(1000)(0.57)] = 0.83
grams

I think the equation should be:

(grams to add) = [ mg./L total * gals of wine * 3.785 gal/L ] / [ 1000
mg/gram * 0.57 ]

Lumping the constants together this could be simplified to:

(grams to add) = [mg./L total * gals of wine * 0.00664

where

0.00664 = 3.785/(1000*0.57)

Ray,
I don't see anything wrong with Lum's formula. You want to add 25 ppm
(25 mg/L) of SO2 to a 19 L carboy (5 x 3.785 L). So what qty of K2S2O5
(pot. meta.) do you have to add?

(0.025 g)/L (19 L) / 0.57 = 0.833 g or,

(25 mg/L) (1 g/1000 mg) (5 gal) (3.785 L/gal) / 0.57 = 0,830 g

How did you arrive at 674 grams?

His example has two lines. These a

(30-10 + 5 for guess work) mg/L total. (5 ) (3.785)
( 25) / (1000)(0.57)= 0.83 grams

I take it that the second line is a continuation of the first line. The
first line gives 473.125, therefore the equation is
(473.125)( 25) / (1000)(0.57)= 0.83 grams
or
(473.125)( 25) (0.57)= / (1000)0.83 grams
6.74 = 0.83
This is not true.

Maybe he meant to divide by both 1000 and 0.57 such that the equation should
be written
(473.125)( 25) / ((1000)(0.57))= 0.83 grams

then it gives

20.75 = 0.83

Again not true.

If there is another way to interpret the given equation, then maybe someone
can show me as I just do not see it.

Ray's correct that the equation is wrong - looks like a typo from an
omitted division sign. Instead of

(gallons of wine you have) (3.785) (ppm or mg/L of total SO2 you want
to add)/(1000) (0.57)

the formula should read (division added before 0.57:

(gallons of wine you have) (3.785) (ppm or mg/L of total SO2 you want
to add)/(1000) /(0.57)

This gives the 0.83 for the example cited. The interpretation is

(gals of wine) * (3.785) = litres of wine to treat
litres if wine * ppm = mg of SO2 to add to get desired ppm
mg / 1000 = g of SO2 to add
g * 0.57 = g of potassium sulifte needed to get desired g of SO2

I have created some software that calculates sulphite additions. You can
choose teaspoons as the measurement unit if you wish.

I have a downloadable version he
http://www.fermsoft.com/sulphite.html

And an online version here (requires Java):
http://www.fermsoft.com/sulphonline.php

Or you can create a personalized sulphite addition table he

All are completely free.

I cheat; I consider:

1/8 teaspoon per 5 gal (US) to be 20 PPM.
1/4 teaspoon per 5 gal (US) to be 40 PPM.

Technically that is 10% low, but I figure there are enough variables
that affect this such as age of the actual chemicals that measuring
with a balance is just not worth the effort.

I use the spoons correctly; I over-fill and wipe them flat with the
side of another spoon. It works for me. I'm not saying you shouldn't
do the calculations, just that this is one of the areas where close has
been good enough for me over the years.

Hi Rick

Normal dose for powder is 1/4 tsp for 5 Gallons. Normal dose for
Campden tablets is 1 per gallon. (5 for 5 gallons). With nothing more than
this to go on, 1 tablet = 1/20 tsp powder. HTH
