It ’s not rare to store coffee in the fridge or freezer to keep the bean fresh over long periods of time . The logic is simple , even intuitive : We keep many of our fruits and veggies from run low bad by putting them in the deep-freeze , and coffee is no unlike . Except , as it become out , it is . According to arecent study , stash away deep brown at lower temperatures does n’t just keep the bonce refreshed : It can modify the way the bean are ground which , in turning , may improve flavor .
Gizmodoreports that a team of scientists at the University of Bath teamed up with local coffee shop class owner Maxwell Colonna - Dashwood to quiz the effects of temperature on coffee beans . They salt away cup of bean for several hours on a countertop , in a freezer , in a bathing tub of dry glass , and in a vat of liquid atomic number 7 , then ground them in a coffee grinder , and compare the results .
researcher focused predominantly on two characteristic of the dry land bean widely believed to affect flavour : particle size and particle size dispersion . They found that colder edible bean produced both smaller particle and more undifferentiated atom sizes when undercoat . That is , inhuman bean produced a finer , more even grind .
According to the study , which was published in the journalScientific Reports , these findings have a mountain range of deduction all along the concatenation of coffee production and consumption . First , researcher argue that , for coffee suppliers , the more uniform grind produced by coolheaded beans could cut back the amount of bean ultimately waste without being take out . For coffee berry imbiber , meanwhile , cooling beans reduces the amount of mass red ink through evaporation , which could potentially “ demonstrate increased aroma and or flavor in the eventual brew cup . ” The investigator believe that their findings could one day convert the way chocolate is transported , stored , and brewed around the world . But for now , if you ’ve been fight to resolve whether to store your coffee beans cold or at room temperature , the study shows it might be a honest melodic theme to just toss away them in the freezer .
