How long does a bottle of wine last once opened?
Good wine is expensive. My husband and I enjoy a drink once a month or less, but we are tired of throwing expensive wine.
is a facet of your question that has not been addressed yet. I think it is most important to you as a wine drinker so frequent that the issue of long lasting freshness wine .. a good wine is not always expensive. There are many "good" wines to be had for less than $ 20 a bottle .. go to a wine shop and ask .. if you say different, do not shop there anymore. find another wine shop. ask the sommelier hours next time you visit a restaurant or go to a flamboyant wine tasting .. will tell you too. As for your question of how long things stay fresh, see the site I listed as a source ..
