I have been recommending the beautiful wooden wine coolers made by Rob Thomson for some time now, but I thought I really should provide some evidence to back this up. Yes, they are beautiful and an asset to any wine lover, but do they really keep your wine cool? I decided it to put it to the test for this wine cooler review.
I decided to compare the temperature of wine bottles, all chilled in the fridge overnight, in three different categories – a control bottle, left on the table at room temperature, one in the wooden cooler, and one in a terracotta cooler I bought a few years ago at a Jamie at Home event. I measured the ambient temperature at the time of each reading, and measured the temperature of each bottle at 0, 15, 30, 45, 60, 90, 120, 150 and 180 minutes.
I didn’t wish to open three bottles at the same time so used an external wraparound thermometer (“Connoisseur” from Barcraft). I am unable to verify its accuracy. The scale goes up in two degree intervals so some readings, for example, fell between two readings and are given as the number in between e.g. 12-14 was recorded as 13.
The results can be seen in the table and graph below:
It is quite obvious that in the first hour especially after removing a wine bottle from a fridge that Rob’s handcrafted wooden wine cooler keeps the wine markedly cooler than either no cooler or the terracotta cooler, in fact 4° cooler than the control after 30 minutes. Throughout the whole three hours, the wooden cooler was consistently more effective than the terracotta cooler or no cooler at keeping the wine bottle cool.
After 150 minutes, the wooden wine cooler still maintained the bottle’s temperature 3°C cooler than the control and 2º cooler than the bottle in the terracotta cooler, and after three hours there was still a 4º difference compared to the control bottle.
Unsurprisingly, since wood is a heat insulator, Rob’s wooden wine cooler is effective at keeping chilled wine 3-4°C cooler than either a terracotta “cooler” or no cooler. The difference is greatest in the first hour after removing bottles from the fridge. Therefore, I will happily continue to recommend Rob’s coolers.
