Acid Titration Test Kit

[Tom]

Yes they do have a shelf life

Sodium Hydroxide I think has a 1 year shelf life
Either way I always get fresh each year OR, I run out most of the times as I make alot of wines.

The kit I showed him and am reading the directions from is made by Country Wines in Pittsburgh PA

I agree with that Tom, I also get a new one each year.

Different kits different directions.
Hard to believe he's only getting .20% which is very low.

The one I use is a 3 cc test.

1) Draw off 3 cc of wine/must.
2) add 3-4 drops indicator solution
3) draw 3 cc of sodium hydroxide
4) Add sodium hydroxide slowly (until color change)
5) Titration = (CCs of sodium hydroxide used) X .25


Question: Is there any dis-advantage in using the smaller sample?

Same as mine. If there are disadvantages, I don't want to know - I've been pleased with the results I'm getting.

That is the same one/instructions that i use. It seems to work very well for me.

Mine is the same as Rod's. Take #CC to perm change color then multiply by .75.
