Hi Friends,

My winemaking has benefited from this newsgroup for a number of years
now, so I want to return the favor. In my spare time, I have created
some Microsoft Office applications (Excel and Access) that have helped
me in my winemaking. I hope you will find them useful as well, and I
welcome your suggestions for improvement.

Please note when you respond to this e-mail to remove spaces on either
side of the @ sign.

In addition to using my software, please take the time to look at the
rest of my web site.

Best Regards,

Gary Flye

I took a quick look. Its a cool little tool. I currently do all my
work in excel, so I'll just paste this into my files. Thanks
One question though, you have TA as 7.0 and 6.0 on one of the sheets.
do you mean 0.7 and 0.6? What units are you using?
thanks

Some refer to TA in percent (0.6%) and others in g/l (6g/l). g/l is
the more accepted term now.

The other weird thing about acids is the French may still use sulfuric
as their 'expressed acid' while the rest of the world uses tartaric.
That makes theirs look a little lower in their literature. Any time
you refer to a TA the most correct way to do it is to state the units
and state what it's expressed by, for example: "0.6% expressed as
tartaric".

It's kind of like miles and kilometers... :O)

Joe

so does .6% in fact equal 6g/l, or is there some conversion?

Hi I just thought I would chip in to add to Joe's point that as well
as France, I believe the UK also expresses sulphuric as the expressed
acid type - my Ritchies acid test kit does anyway. So perhaps it is a
European thing in general?

Cheers, Jim

No it is not a General European thing.

In Holland, Belgium and Germany tartaric acid is used as the reference.
As far as I know Australia also uses tartaric acid as the reference.

Yes. 0.6% of 1000 grams is 6 grams. (1 liter of distilled water at
standard temperature and pressure weighs 1000 grams, that's why they
equate so well.)

Marc,

My spreadsheet represents acidity in grams per liter, whereas you are
expecting it to be in % tartaric. They are essentially the same. But I
appreciate your observation, and will give it some thought.

Gary

Thanks for the answer Luc, much obliged
