By "coffee," I mean ground coffee beans with water filtered through, and only that. I like strong, but light roast, because I actually like coffee beans and I don't like it when people cook all of the flavor (and a lot of the caffeine) out of them (some people put milk and/or sugar in, but I only put sugar in coffee that's truly terrible, like Starbucks). By "espresso," I mean a shot of concentrated espresso roast coffee. I've never actually seen what you are calling a long black, but I think it would taste of watered-down espresso. In the US, I've only seen espresso in shot form, or in either macchiato, cappuccino or latte.
So, short answer, espresso shot in the filter coffee.
Ally, I should be doing homework that was due today or tomorrow, but I'm trying to find what people see in "Glee."
After the first episode, I hate it. I'm sure this view is partially influenced by the fact that it's a show about Glee club, which is something I detest, as well as the fact that they decided to do "Don't Stop Believing," which every a capella group ever has performed.
I'll probably give it two more episodes before I decide that I'm not missing anything.
