Keurig K-cups

How long should it take for the water to drip through for a single cup? I measured various methods I use and got:

  • Melitta cone with re-usable metal filter: 32 seconds (less than a minute)
  • Melitta cone with paper filter: 32 seconds (less than a minute)
  • Ankar two-piece “cone”: 1 minute 40 seconds
  • Bialetti espresso machine (small): 3 minutes, 40 seconds
  • Vietnamese coffee press.filter: 6 minutes, 6 seconds

I tend to use the Ankar as my standard, but the wide variation in times has left me wondering.

I haven’t a clue but our counter top brewer drips hot water into a filter containing 6 level scoops of supermarket grade coffee grounds (approx 6 level Tbsp) and then it gravity drips through the grounds and into the pot with a final yield of 12 cups. Never timed it but per cup its a significantly slower process than the Kurig Machine that used pressure to force the hot water through the cup holding the grounds.

My guess is the longer a given amount of hot water is in contact with the grounds the more flavor will be extracted from the grounds. As a result, the fast pressurized coffee machines require more grounds per cup.

I know for a fact that the fast brewing machines in a 7-11 or Wawa require a lot more coffer grounds per cup than a much slower home brewer.

For about $6 lb, Costco has a really excellent organic, fair trade Cuban Mayorga coffee. Not too dark, choclately notes and full bodied, no bitterness. My other regular coffee, Jim’s organic Ethiopian Sidamo runs more like $16 per lb. I love the Mayorga and the savings. Of course, my local roaster is more like $20 per lb, I believe.

So much depends on how much coffee you use, what grind it is, and how fresh it is, with bloom.

Standard coffee scoop (2T), usually espresso grind, sometimes regular grind. It is already ground, and I go through a brick or can in about a month.

You use one standard scoop per cup? No more? There’s room for more, right?

I drink, typically, from a 16 oz mug, so that’s three really rounded scoops, for comparison. Medium to fine grind.

The Canadian two-piece is pretty much a one-scoop contraption, as is the Bialetti and the smallest Vietnamese filter. I suppose I could put more in the cone and the larger Vietnamese filter.

But the ones limited to one scoop also limit the amount of water to about 6 ounces as well, so I’m not trying to make a pint of coffee from a single scoop. (I am reminded of my father, who used to make three or four cups of tea from a single tea bag. Child of the Depression…)

No need for K-cups . . . . :wink:
