Eagles Over the Kennebec

May I recommend Stash Tea's Moroccan Mint? It is green tea, but with (actual) mint added for Ooomph. It's a very laid back, easy sipping blend, and good hot or cold. Enough caffeine to maintain momentum but not enough that you can't drink it all afternoon if you so desire. Stash also has one called "Breakfast in Paris" which is a gunpowder black (what puts the "breakfast" in the Irish Breakfast tea) base with lavender and vanilla added, which is wonderful with a little dribble of almond milk first thing. Twinings also makes an English Breakfast, which I also like. I have one of those "commute" mugs that will keep tea hot for hours. It's a Two Cup mug and I usually use a bag of English or Irish Breakfast with either Tazo's Chai or Breakfast in Paris. Sets me up for the day. I suspect that you will find your favorites among the gunpowder black blends.
