residue at cork

Apr 24, 2008 8 Replies

I tried a California merlot & discovered a thick, dark residue on the inside of the bottle after it was corked. Ick! What is it? I presume this is something to do with improper storage.



Thanks in advance, my fellow wine lovers!! :)


Many red wines will drop a sediment after bottling. It's a totally natural thing and in no way harms the wine. The stuff on the inside of the cork is often that same sediment combined with crystals of tartaric acid, another natural component of wine. The only thing I'd suggest is that you don't agitate the bottle too much when pouring from a bottle with sediment in it, as the sediment itself will impart a bitter taste to the wine. If it's been agitated, you can pour the wine through a coffee filter to remove the sediment.

Coffee filter; great idea. The sediment was very heavy, even coating the inside of the bottle once it was empty, and it was apparent in the glass. Bleagh.

was not stored on side. should be stored label side up. should be poured label side up.

A rather crude Merlot from Sonoma.

I mean the name. If the wine was bad, crude and you rated it at a 70 I'd like to know what it is so I don't buy it too.

I knew ya did ;) If I knew it I would share and if I come upon it again I'll make a note of it. :)
