A porch crawler is a mixed beverage made primarily of beer, liquor, and a sweetening agent (for instance, lemonade concentrate). The most standard liquors for the drink are vodka, gin, rum, or whiskey. It’s ideal for parties and the ingredients are scaled to make a whole pitcher rather than a drink at a time, anyway. A good quality beer makes the cocktail even better.
Fill a highball glass with ice and add a few lemon slices.
Add vodka and frozen lemonade concentrate and stir.
Top with Harp lager beer.
