We have been testing some different wine glasses in the Arizona heat for a couple of months now… I know, I know… why does it take 2 months to test wine glasses? Well, we had to see if different kinds of wines would changing the thermodynamics of the glasses at different temperatures, and different humidities…ah who am I kidding… it was just an excuse to drink wine… (Guilty as charged your honor)
However, after testing different thicknesses of glass, even frozen ones, as well as plastic, insulated and frozen stainless steel we were super impressed with one design which really did a great job.
The testing was conducted outside on the deck (where else would you do this?) in the late afternoon with the Arizona sun blazing right through July and most of August. If you have ever been to Arizona during these months, you won’t quickly forget how hot it really is.
The true test was to have white wine directly from the fridge (set at 36 degrees – my wife likes her wine very cold) in a glass, sitting on the outdoor patio table in temperatures ranging from 100 degrees through to an excruciating 110 degrees. Any hotter than 110 and the Wine Drinker’s Union of America would have stepped in and staged an intervention… anyway back to the test… The wine needed to be “not noticeably warmer” at the end of the glass and still “crisp” enough that you would drink it.
The summer sun in Arizona at 5pm can be brutal and is still high enough in the sky to hit the table directly, so we ended up at least partly having the glasses sit directly in the sun for some 20 minutes, as the wine volume was systematically reduced in each glass at regular intervals. That’s code for “we drank it”.
Clearly, the non-insulated glass and plastic options were eliminated from the test in the first week, leaving several metal options and then cutting the list down to 2.
The stainless steel options worked pretty well indoors and outside in the overcast weather, but as soon as the sun hit them they absorbed the heat and transferred it to the wine pretty quickly. Even just the ambient temperature seemed to heat up the steel fairly quickly. Certainly better than glass but they did not meet the criteria. At this point, we were beginning to look for frozen wrap options and even toyed with the idea of inventing some wine glass coasters which you could freeze and would cradle the glass and cool the wine, but our design skills seemed to leave something to be desired after our 2nd test of the day for some reason?
The clear winner was the REDUCE vacuum insulated set, which not only kept the wine cold overall but in the direct sun, was able to retain the temperature of the wine inside, while the exterior of the glass was above 100 degrees.
We were so impressed that we have adopted a family of 8 of these glasses and use them exclusively.
The main problem was that the bottle of wine would heat up on the table, so we needed to do a “wine run” to the fridge each time we ran low…
Thankfully, the company also came out with a bottle cooler made with the same vacuum insulation which also has a screw on collar, so we are having to run the tests again – oh darn!!!
