A lot of my writer friends basically live on coffee. I like it every now and then, but it’s not a daily thing for me. It’s what I get when I am grabbing breakfast while out and about, not what I make every morning to get going.
At Castle Frostbite, we drink tea instead, and a lot of it.
This is our morning fuel. It’s Ostfriesentee, a German tea blend from East Frisia (where they drink more tea per capita than anyone else in the world.) It’s a pretty strong Assam/Ceylon blend.
This is what I drink when I am working. On a normal day, I probably have four or five cups of tea before lunch. The East Frisians drink theirs with cream and rock sugar, but ain’t nobody got time for East Frisian tea ceremonies around here, so I drink mine plain and black.
You can get it all over northern Germany, but it’s almost impossible to find in the US, so I bring back ten pounds or so whenever I visit the family, and my brother kindly ships me some whenever I can’t make it over in time before our stock runs low. But every time I do bring back a suitcase full of neatly packaged one-pound packs of black tea, I do feel a little bit like an international drug smuggler, even if it’s a legal drug. 
Upton Tea carries 3 different East Frisian style blends of tea, at least one of which is blended in Germany. They’re in Massachusetts and are a mail order/internet company, so it could be a convenient source if you run low. It does lose some of the intrigue of bringing it back from Germany with you though…
Dalmayer’s coffee is mine. In a communist-era that coffee was part of the aid packages from the west. I still think about that as a luxury even if today it is relatively cheap and common in my country.
