Welcome to the forum and to the wine experience! I, too, am a rookie, having become interested in wine just about a year ago. The previous posts have given you some wonderful tips. I can add a couple of things that have helped me dramatically in my adventure.
*Start your own tasting notes-( for the present, don't be too
concerned with the proper verbage)When you taste a new wine
simply jot down the name, varietal, vintage, etc. What do you
like/not like about ? Would you buy it again ? You can devise
a basic rating system of your own. (A-B-C-D or 1 - 5 stars.)
This will help you see how various wines stack-up according to
YOUR tastes, which is what really matters !
*Purchase and sample as many wines as your budget allows,but
try to avoid the urge to "load-up" on those you like. Your tastes
will likely evolve over time, and you won't want a glut of wines
you no longer care for. (speaking from experience on this.
*Most of all- ENJOY ! Don't be intimidated. We've embarked upon
a lifetime adventure and it's all about the journey !
