How can I tell which wines are dry wines?

[sumbunnyshoney2002]

Hello,
I have been buying lots of different wines to try. I do not really care for dry wines. I am not sure how to tell the difference when its not on the label. So I end up dumping a lot out.
In the cheaper wines, I have been drinking Blackberry wine from Door County in Wisconsin. Its not too sweet.
As you can tell I am just learning.
I would apprecate any help you can give me.
Thank You,
Sandy
