Discovered in Maplin - a rather "nifty" wine bottle thermometer:

At only £2.49 (on offer until 16.04.13), this is a useful little "gizmo" to check the temperature of your wine. It clips around the bottle, and whilst there is no indication of accuracy, I believe the accuracy is sufficient for practical purposes.
Used it today to ensure the temperature of my bottle of Bordeaux was 17 - 18 degC. :)
