2. 0:09we're gonna cut straight to the chase
3. 0:11should you store your coffee in the
4. 0:13freezer maybe let's get into this in a
5. 0:18little bit more detail talk about when
6. 0:19it's good to use the freezer to store
7. 0:21coffee and ready when it's not to start
8. 0:24with let's talk about why you might want
9. 0:26to store your coffee in the freezer very
10. 0:28cold temperatures are great at slowing
11. 0:30certain kinds of reactions involved in
12. 0:32things going stale freezer temperatures
13. 0:34slow down oxidation they prevent the
14. 0:36loss of volatile aromatic compounds they
15. 0:39just generally slow the staling process
16. 0:40now most domestic freezers don't go cold
17. 0:43enough to completely stop that process I
18. 0:46think the research done by a sort of
19. 0:48famed coffee scientist engineer roaster
20. 0:51builder Mike civets said that you needed
21. 0:53to store coffee at minus 40 that magical
22. 0:57temperature where it doesn't matter what
23. 0:59units you're talking about anyway most
24. 1:01domestic freezers live at about minus 20
25. 1:03degrees Celsius that's good enough to
26. 1:05help slow the process quite dramatically
27. 1:08freezers however have a problem they are
28. 1:11incredibly dry places and those kind of
29. 1:14temperatures Moisture can't stay in the
30. 1:16air it comes out of the air and forms
31. 1:18ice crystals if you've ever owned a
32. 1:20freezer you love seeing that happen and
33. 1:22you'll know that freezers need de-icing
34. 1:23all of that ice all of that buildup has
35. 1:25come from the air now how does that
36. 1:27affect coffee well in an ideal world we
37. 1:31could put coffee in our freezer and it
38. 1:32would slow down the scaling and that
39. 1:34would be great what we want to do
40. 1:36however is really limit the interaction
41. 1:40between the coffee beans that are now
42. 1:41minus 20 degrees Celsius and and any
43. 1:44kind of air or you don't want to do is
44. 1:46this you don't wanna go buy a big kilo
45. 1:50bag and put the whole bag in the freezer
46. 1:52and then every morning
47. 1:55get the bag out get your coffee out put
48. 1:58the bag back in the freezer because all
49. 2:00you're gonna do is introduce lots of
50. 2:01fresh humid air into those beans you can
51. 2:04get crystallization of ice on that
52. 2:06coffee that's just bad in every single
53. 2:08way possible so here's your best
54. 2:11practice if you've bought a kilo of
55. 2:13coffee if you've bought a couple pounds
56. 2:14three five if you've bought more coffee
57. 2:16than you need in the next week or two
58. 2:18then what you want to do is parsley out
59. 2:21into one to two week sort of quantities
60. 2:23then freeze those right you want to get
61. 2:26rid of as much air in whatever you're
62. 2:28freezing in as possible ideally now some
63. 2:32people go as far as vacuum packing it
64. 2:34that's a little extreme and I'm a little
65. 2:36uncomfortable with the amount of wastage
66. 2:38that comes from that there are certain
67. 2:40things that require a vacuum packaging
68. 2:41and I'm okay with that but I think
69. 2:43vacuum packaging coffee just the waste
70. 2:46is a little bit look for me but it is
71. 2:49probably the best possible way to do it
72. 2:51but I wouldn't go so far as to vacuum
73. 2:53seal individual portions unless you had
74. 2:56a coffee that was incredibly expensive
75. 2:57and you were running a very very very
76. 2:59cold freezer sir you've bought that kilo
77. 3:02you want a parcel out to say 250 gram
78. 3:05300 gram 350 gram whatever you prefer in
79. 3:09in to those kind of parcels you can use
80. 3:12freezer approved sort of mason jars if
81. 3:14you want to do that you could obviously
82. 3:15use freezer bags if you want to those
83. 3:17things are reusable and that thing is
84. 3:18good or you can just buy three or four
85. 3:21individual normal sized retail bags and
86. 3:23put all but one in the freezer and then
87. 3:26what you want to do is is take out a
88. 3:28portion the night before you need it do
89. 3:30not open it and let it defrost overnight
90. 3:33little do you find just on the counter
91. 3:35overnight you don't want to open it when
92. 3:37the beans are that cold because you will
93. 3:38get some condensation forming on them
94. 3:40and broadly speaking that's just not
95. 3:42particularly good for coffee you don't
96. 3:43really want to do that if you've just
97. 3:44bought a regular-sized retail bag it's
98. 3:46just not worth you freezing that it's
99. 3:49not just just use it over the next
100. 3:51couple of weeks and you'll be completely
101. 3:52fine you're not gonna do much to really
102. 3:54change the state of that coffee if the
103. 3:57coffee is stale out-of-date to begin
104. 3:59with there's no point freezing it
105. 4:02nothing good will happen there nothing
106. 4:04bad will happen but nothing good will
107. 4:05happen so why bother
108. 4:07in summary if you've got more fresh
109. 4:09roasted coffee than you need in the next
110. 4:11couple of weeks take the excess and
111. 4:13portion it into one to two week portions
112. 4:15seal them air tight get rid of as much
113. 4:18as you can and freeze them and then the
114. 4:20night before you need a portion take it
115. 4:22out of the freezer let it defrost sealed
116. 4:24on the counter the next morning grind
117. 4:26drink enjoy one more piece of business
