title_body: How to transport coffee
upvoted_answer: Actually, I will change the direction to ground coffee. A few months ago, I have seen a nice solution for campers. I took a photo of it for reference at that time. It seems quite useful to me. However, I mostly prepare my 'tasty' coffee at home and drink 'crap' coffee in the office. So it didn't fit me.
  
  Still, here is the invention. A camping style brewer pack. You will need just the hot water in the office. Each pack is single use only. It was just a bit more than regular price. But it was still affordable. Still, you may not like to use this in daily routine.
