Yes, by my experience, you will be able to make a good 10 oz cup of coffee from a single K-cup of Black Tiger--unless you want your coffee strong enough to bench press the coffee maker!
Seriously, I love Black Tiger and use lots of it. Some days, when I want my second mug of the day to be not so strong, I'll actually use one Black Tiger K-cup to make 16 oz of coffee! I put one in the Keurig, press the 8-oz button, and when it is finished open and close the handle and press the 8-oz button again, to end up with one 16-oz cup of coffee made from one Black Tiger K-cup. Very few K-cups are bold and strong enough to do that.
Other days, I make a single 12-oz cup of coffee from a single Black Tiger K-cup, but a single 10-oz cup of Black Tiger from a single K-cup is a bit stronger than I prefer.
Hope that helps!
