Stanley will be introducing a Growler later this year but it was not available for testing.
After thorough scientific testing and field testing and taste tasting as described in the article, the authors concluded:
Sorry, internet: no disastrous fails here. “I have seen many good beers become oxidized and flat, even in just a 24 hour period,” said Brew Master Scruby, “but the growlers tested did a great job preserving the flavor of the beer and retaining the carbonation.” All the stainless steel insulated beer growlers we tested gave us very drinkable brew after 24 hours (including time in the sun and being bounced around in a pack). We saw no leakage from any of the growlers, but, with the help of our master brewer, we were able to tease out the ways in which each one was subtly different. And we went ahead and ranked them, because what good is a test without rankings?
They ranked Most Affordable, Lightest, Best Value and settled on their Beer Snob's pick - The MiiR 64 oz Vacuum Insulated Growler.
Shameless plug, you can now take that wonderful Arizona Wilderness Brewing Craft beer with you on trips.
