I've been asked to do a brief talk on test kits at Grapefest this year.
I'm not 100% certain on what I'll be covering, but I was thinking about doing some demonstrations on the correct use. I'll be trying to do it with a mind to the audience so lab equipment will be a no-no where possible.
At the moment I can think of a couple of tests which I should be able to do without any special equipment:
Acid testing using a richies test kit (yes, it is incredibly easy to fluff this test. Easier to make a mistake with this than using a pH probe).
Acid Testing using a pH probe (this will hoefully be short, since the bulk will be covered in the earlier demo).
Free SO2. I'm only planning covering the Aeration/oxidation method with this as it requires simple chemicals, and simple equipment. It is also considered to be more accurate than the Ripper method.
Total SO2. It's not really possible on the small scale, but I'll go over the details of how it's done (not that different from the free really.
Malo-lactic-fermentation Nice, easy test. Bullet proof. Get some mixed acid and some wine, do the test, get your answer. Easy. Except the chemicals are flammable...
If you would like anything else demonstrated or brought down let me know and I'll do my best
