Earl,
If you follow the directions included in the kit your wine will come out fine. It is normal to ask lots of questions and be concerned at times but these kits are basically foolproof and the only thing that could go wrong is lack of proper sanitation causing an issue.
Relax and as Tim says follow the directions exactly eliminating no detail!
For those who don't know Tim Vandergrift is the Technical Services Manager for Winexpert Ltd.
Here is an explanation from Tim Vandergrift on what the bentonite does for their wine kits:
"The bentonite is in the primary fermentation for two reasons:
<UL>
<LI>It helps increase the rate of yeast growth, acting as an accelerant for budding activity
<LI>It helps settle out yeast cells post-fermentation, and prevents hazes from early autolysing cells.</LI>[/list]
It really doesn't have much to do with heat hazes, as we don't heat-extract our juices (when you do heat extractions the colour compounds aren't stable--they just drop out of suspension after a while) and is mainly concerned with compacting the sediment bed, not with ultimately clarifying a post-fermentation wine.
The difference in bentonite preparation has to do with the difference in all of the bentonites available on the market. Some rehydrate easily, others are nearly hygroscopic, and need to be soaked for hours before they will perform their function."
