You probably want to rethink operating out of your home. When you get your federal license which is required for you to produce alcohol, you are obliged to allow BATF inspectors in on demand.
Information on obtaining the license here: https://www.ttb.gov/wine/federal_app.shtml
You also need a state license: https://lcb.wa.gov/enforcement/winery-faq
Your winery name on the application has no bearing on trademarks or brands. Your license(s) give no trademark rights in themselves. Using the mark in commerce will give you some rights, registration of that mark will give more.
Every label you affix to a bottle must have prior approval from the TTB. Been through that myself a few times. Sometimes, it's perfunctory. Sometimes, they seem to develop an attitude. For instance, one brand we put out had VH (the initials of our winery) in morse code on the label. THe TTB gave us grief as they thought that there was some coded message. Another bottle (Code Purple Shiraz) had a "Matrix-like" background on the label which contained a longer encrypted message. That they approved. There are strict rules about things that MUST be on the bottle and things that Must NOT be.
Note wine advertising is highly restricted. While you don't need prior approval from the TTB, the TTB does enforce the laws on this (and you may wish to run your ideas by them).
There's a lot more to this. In fact, there are some books that may help you. Both the "For Dummies" and the "Complete Idiot" series have running small winery books. You're still likely to want to have the consultation of an attorney who is in the industry.
