Time tables are just guidelines. But it must be about finished. It is not
going to go much below 0.991. (I assume your decimal is in the wrong
place.) That is very low. Temperature is fine. Incidently, and I am not
pocking fun, fizzing is not a determination for wine fermenting. The
question is, is the airlock still working? If it stops for a day then it is
probably finished, but give it a week more to be sure.

They are exactly right. But your wine is very dry already. If you are not
going to add any sweetener, you do not need to add the sorbate. It
stabalizes the wine so it will not restart fermentation in the bottle. But
at your SG, there will be no sugar left so that is not a problem. Just one
chemical that does not need to be added.

No, it is fine.

You indicated that you are checking it dayly. I know they suggest this in
many kit instructions but it is really not necessary and can be bad for the
wine. Every time you pop off the airlock and take a sample air is getting
to your wine. This is not good in the later stages of fermentation. If you
leave it alone the CO2 being produced and pushing out the airlock will
protect your wine. You defete this protection when you open it. As long as
the airlock is working you know it is fermenting normally so there is no
need to test it. When it stops fermenting you should test it to see that
all the sugar was used up (SG condiderably less than 1.000). Once you test
it this way you should top up as the air that gets in while testing can be
detrimental.
