Well, it's been a long journey for me and I still feel like a rookie! It depends on how serious you plan on getting when it comes to wine making. The best advice I could give you is to go onto the beginners forum. There is so much good information to help you with understanding the whole process. Mostly, get the terminology down, then you will be able to understand what you are learning. As far as tools, I would say a pH meter was the best investment that I have made as this can help you understand where your wine is starting at as far as how balanced it is. Besides this I am assuming that you have a hydrometer, as you can't go without this tool. The other big thing that can help you is to write down everything that you do with your wine. When you started it, type of yeast, pH, how long it fermented, etc. If you do this and your wine didn't turn out then you can get help with learning what went wrong. This site has so many wise and helping people that can walk you through any problems you have.
