French Press: One of the cooler things I have bought is a Bodum French Press.
Way back when, I used to brew my coffee in the morning with coffee maker, put it in a thermos and carry it to work. The coffee was OK. Some days I would treat myself and get Dunkin Donuts coffee, but hated paying almost $3 for a large cup of coffee.
At work one day I watched a co-worker offering coffee from his French Press, and I was blown away. It was delicious and simple. And cheap!
I walk over to Empire Coffee in Hoboken or McNulty's on Christopher Street every other week and buy whole bean roasts and it costs me from $4 to $18 per 1/2 pound depending on the region. That will last me two, maybe three weeks. 15 days can cost me about $45 dollars from buying Dunkin Donuts everyday.
Then, I bought on Amazon.com a Krups coffee grinder, and it works great.
My morning routine is simple, before I leave my house for work I grind my coffee and take it into the office in a Ziploc bag. My French Press is in the office, at my desk. I add my coffee to the pot and fill the French Press with the hot water in our company kitchen. I stir it and let it sit for 4 minutes. That's it. Coffee is ready, and it's a trillion times better than what my company has sitting in the kitchen and better than Dunkin Donuts coffee (buy the Jamaican High Mountain Blue coffee if you don't believe me!)
At the end of the day, I clean the French Press simply by pouring out the old grinds and a quick clean under running water, letting it air dry on my desk for the next day. Once a week I take it home and put it in the dishwasher. If you are like me and work in an office, and have access to these things, you will save a TREMENDOUS amount of money a day by not buying coffee. Plus, if you love Starbucks or Dunkin Donuts, just buy their coffee and brew it yourself. You will taste the difference.
