I have been making homemade wine now for about 7 years with great success. My wine making has always been from fresh juice or kits. My question is...whenever I open a bottle of wine, no matter its age, it initially has a somewhat homemade odor (tough to describe and not necessarily offensive) that I do not notice in commercial wines. I find that after uncorking a bottle, it almost always smells and tastes better on day two. This seems to ring true no matter what type of wine juice is used. I am assuming something is precipitating out of the wine after it is uncorked, but don't understand what or why. Can you shed any light on what is happening here?Name: Bob D. State: Massachusetts
Hello Bob,
I'm not sure how to answer your question. This is not a normal thing to experience, and the fact that you are experiencing it with all homemade wines tells me that there may be some fundamental flaw going on in the wine making process.
If you could describe the odor more clearly and specifically we might be able to hone in on it a little better, but at this point all I can do is try to speculate. Things that come to mind are:
  • Squeezing a wet cork over the wine bottle when bottling and allowing the liquid to drip into the wine.
  • Too much sulfite such as sodium metabisulfite or Campden tablets being used throughout the wine making process.
  • Bottling the wine to soon and trapping off-gases from the wine yeasts' fermentation.
  • Fermenting at too warm of a temperature. 78°F and above can be a problem.
I'm not saying that any of these things are going on. They are only guesses to give you an idea of what types of things to consider. In reality if could be one of a hundred things. Just review what you do and see what you can come up with.
If it turns out you still have no idea, here's what I would focus on with your next batch. After the fermentation has completed, give the wine plenty of time to clear, more so than with your past batches. Once you get to the point of bottling the wine, degas it thoroughly. This can be done through shaking and agitation, but I have found that the safest, most efficient and most thorough way to degas a wine is to use a degassing/mixing paddle.
A degassing/mixing paddle will not splash the wine. Splashing is something you want to avoid because it saturates oxygen into the wine and promote wine oxidation.
The hope here is to try some simple things first that may have some affect on the aroma of the wine. Time will tell if this is a solution. If you still get the same results, then you will need to move on to something else, such as fermentation temperature, etc.
