some info

[curious]

hi, new not only to this site, but also to drinking wine. My hubby and I have considered occasionally haveing some with our dinner, or just sharing time with each other.
Now, where to start!!
I have been reading posts here, but have bunches of questions.

One is, how many glasses can you get out of a bottle, how long with the bottle last after it is opened, as we won't drink a lot, just a glass each.

I will save the others for later.
Thanks
