I have been making wine for the past 3 years, and have been taking pictures for the past six. I started with a Canon EOS Rebel XTi, moved to the 40D, Then the 7D, and now shoot with the 5D Mark 1, and AE-1 Program (35mm film).
I still make wine to fund the nasty, and expensive photography habit. Not sure if I'll ever go completely professional taking pictures, seeing as how I still have yet to sell any, but if I can take a picture someone will want to look at (even digitally), then I know I've done a good job. I'm a simple kind of guy, really.
