title_body: Can aged home made wine be restored?
upvoted_answer: This is pure speculation, but here is what I think. The wine is either palatable or not. The traditional way to deal with sediment is decanting. This is where the wine is slowly poured into a container (a decanter) while observing the sediment, usually with a bright light behind the bottle. The idea is to stop pouring just before the sediment escapes. You lose some liquid in the process. I suppose you could try pouring through a coffee filter too. Once decanted the wine should probably be drunk within a day or two.
  Fine wine is often aged for 30 years, but it is very likely the wine is spoiled or at least well past its prime. The alcohol in the wine should keep it safe to drink, but since it was home made I can only speculate about that.
