Well, there are plenty of prison hooch websites, too, but that doesn't mean it'll be good wine!
The problem with plastic water bottles is not necessarily the "plastic taste" it might impart (although that is bad, too)- the problem is oxygen permeability. You want 0% oxygen contacting your wine after fermentation and you'll leave it in secondary maybe 6 months or more at times. That would be a huge problem- you want to protect your wine from light and oxygen. I use glass carboys with an airlock to protect them from oxygen and cover them with towels or dark t-shirts to keep out the light.
