Wine diamonds

Date:21 October 2015 Tags:, ,

Called wine diamonds by connoisseurs, the tiny crystals that form in aged wines are a build-up of tartrates, especially potassium bitartrate. The crystals are found to form when wine is stored in cold temperatures, and can often be found at the bottom of a wine bottle.

The image above shows the build-up on the cork of a bottle.
