advice on budget red to store

[rvoller]

I recently went to a local vineyard and bought a bottle of red. I was told there if I wait and store the wine for a couple of years it will taste better. So im just looking at it wondering what it tastes like. This gave me an idea of visiting a wineshop/supermarket and storing several budget bottles of red (£5-7). Im curious of what the outcome will be. Im no wine expert but starting to experiment with my taste buds. Can I pick and choose any bottle of red and store or are there any general rules to follow like specific grapes/regions etc.? My favorite grapes are rioja, merlot and carbenate sauvigon/shiraz so far from my limited experience as a wine drinker and would like to mature these?. I dont want to find out after a couple of years a made the wrong mistake from my naivety. Thanks for the advice.
