This drink contains a refreshing combination of ingredients — the herbaceous mint, the tart lime, the hot, spicy ginger, and the crisp, bright gin. When used in drinks, gin's botanicals have the ability to cut through the sweetness of liqueurs and sugar. The botanicals stimulate the palate and keep it feeling fresh and clean. Gin also pushes flavors forward (much the way a squeeze of lemon does) without altering the flavor profiles. This recipe makes 1 gallon, which yields approximately 25 to 30 drinks, depending on the size of the highball glasses. This sounds like a lot, but it's not. A gallon would go very quickly for a party of 6 people. For home entertaining, you can premix all of the liquids a couple of hours ahead and then store in the refrigerator. When you're ready to serve the drinks, just mete out the liquid into a mixing glass and muddle a sprig of mint into each. It makes enjoying your own party a lot easier, rather than having to worry about continual prep. And please, no shortcuts here: Do not presqueeze the lime juice more than only a few hours ahead. It loses its vitality quickly. And do not infuse the mint into this (or any drink). It takes on a funky, vegetal quality, which mars the taste of the drink. Using commercial ginger beer is not recommended, as it is too sweet. Nonalcoholic note: Without gin, this makes a very refreshing nonalcoholic beverage!
