Ask Wine Wizard

When I opened my blueberry-Zinfandel wine I was struck by a strong acetone-type smell. Am I experiencing bottle sickness or TCA?

Dear Wine Wizard, About a month ago I bottled my first blueberry Bordeaux. I used fresh blueberries and red Zinfandel concentrate. I adjusted the taste at bottling and it was great! The wine had a nice fruity nose, complex body and a smooth finish. For Christmas I opened a bottle to check on the aging progress. I was immediately struck by a strong solvent-like smell, something like acetone. The fruity nose I had experienced at bottling was gone. The acetone smell dispersed after a minute or so and the taste of the wine was OK, but had not improved since the bottling. Am I experiencing “bottle sickness” or something worse (TCA formation)?

Your “acetone” or “TCA” smell could have a few causes. My first suspicion
