There are bartenders who make a living mixing cocktails, and baristas whose wages are earned behind espresso machines. There are high-concept tea masters, sommeliers, and soda jerks, too. At home we are never expected to be any of these, but when guests arrive for your holiday parties some simple instruction might be helpful. After all, there's a week's worth of celebrating still to be done.
I tend to restrict drinks at my dinner parties to champagne and wine and perhaps one great cocktail. I suggest you try all the ideas here, or create your own, but choose only one as your "house special." "What you don't need," says wine writer Anthony Dias Blue, "is people sidling up to your bar expecting a Singapore Sling or a mai tai," or both!
I know a thing or two about drinks. At age 16, I was a bartender, illegally, at the Olde London Fishery in Queens, New York. I was tall for my age and looked the part. Next, I had the ultimate pleasure of helping create two of New York's most spectacular bars -- the Rainbow Promenade at the Rainbow Room atop Rockefeller Center, where Sleepless in Seattle was shot, and the Greatest Bar on Earth on the 106th floor of the now legendary Windows on the World. A great drink is always remembered.
Even though I take all those silly self portraits of me doing absolutely nothing and blog about trips to pretty places I am not much of the relaxing type of guy. I’m actually quite the opposite and find myself nervous or antsy when I’m sitting still. The thought of midday naps freak me out and stopping to sit down for tea or coffee in the afternoon is a luxury I rarely allow myself. Even if I had the time I’d still feel like I was missing something or that something terrible would happen because I wasn’t working working working working working.
Because our holiday parties tend to revolve around themes and menus of yesterday (I blame my house, it’s terribly 1950s to the extreme, and no, I wouldn’t change a thing), I wanted to experiment with a category of drinks that are probably better suited to Patagonia rather than Sunny Southern California: hot cocktails.
A coffee farmer shared with me that the most injury prone job picking coffee involves climbing. When one hand is holding the tree and the other a machete--what are you left with to swat the bugs? 
Tired of being the host and the bartender at your party? This is the perfect solution...a festive drink your guests can serve themselves.
