Have you experienced the feeling that you open a bottle of your homemade wine and it seems to be a different wine from other bottles of the same batch? I have noticed the difference from one day to the following, so it is not a matter of aging. I know that wine flavor may depend on the context, for example, what you are eating or what you have eaten, but I have noticed big differences in the wood tannins presence, for example. Any explanation or it´s just me?
