Coffee Joulies are stainless steel beans filled with aphase change materialthat occupy passion as it melt — chill down horrifically live coffee — and then releases that heat as it re - solidifies — then keeping your chocolate warm for longer .
The claim is that the Joulies cool down your coffee down 3x faster than normal , and then maintain the “ right ” temperature up to double as long , though the latter gist is highly dependent on how insulate your deep brown cup is . ( plain , the more heat the cup releases , the harder it is for the Joulies to work . )
Click to viewThe thawing point of the PCM inside of the Joulies is 140 degree , so ostensibly that ’s the “ right ” temperature they ’re aiming for . ( Higher temps will do the Joulies to absorb heat as the material inside melt , until it reach 140 degrees , at which stop the PCM will get re - solidifying , releasing heat — keeping the coffee at around 140 academic degree . ) Coffee is typically brew at around 200 arcdegree , give or take ( unless you ’re using a stinking habitation drip machine ) , so you ’re talking about cooling something down by like 60 degrees three times faster . I ’m in spades funny what the effect on the taste of the coffee is — the flavor of deep brown change as it cools , and one of the reasons quality - focused coffee stripe do n’t pull espresso directly over chicken feed is that it gets rancid . ( The temporary change with Joulies would n’t be quite that dramatic , obviously , but I ’m wondering if there ’s not some effect on flavour . )
If your tongue has been tortured by to a fault red-hot burnt umber one too many times and you do n’t remember these are voodoo pebble , fortunately , you may plow your money into the Kickstarter project—$40 will net you five Joulies of your very own . [ KickstarterviaNick Cho ]
