Most of my Career was working mid-nites, as a result, I’ve drank ALOT of Coffee.... mostly restaurant or dunkin coffee. At home, Maxwell House in a Percolator, just like the old commercial they had.
Went thru a couple of Mr. Coffee machines using 8 O’clock , I really like the 8 O’clock coffee.
The Wife got a Keurig and been getting the Colombian Supremo from Sams, a medium dark .
I’ve cut WAY back on coffee, max 2 cups a day.
The two strongest coffee’s I ever had was Cuban Expresso coffee, served in a paper shot sized cup and Cowboy Coffee.
The Cowboy Coffee was on a week long Elk Hunt in Wyoming back in the 80s...Back than, I would drink 4-5 cups a day.
The Leader of the group was a 100% good guy... He had a S&W .41 Magnum and I had my 29 and we got along great.
First morning, He asked me to bring back water from the Stream not far away.... Handed me a large pot... When I got back to the cook tent , he placed the pot on the fire and when it was boiling, threw in what seemed like a pound of ground coffee. ( hard to tell how much, as we packed everything in on horses, and the coffee was in a large sack).
As the coffee came to a rolling boil, I could see the grounds swirling and thought how were we going to drink this....after awhile, Stan threw a handful of egg shells from our breakfast in the boiling coffee. It immediately settled the grounds.
That was some strong coffee... one cup was plenty for me. We had a total of 10 in our Hunting party and had coffee made like this every day.
Best hunting trip I ever had.
