In a small saucepan, bring ¼ cup water, honey, and halved jalapeño to a boil over medium-high heat. Remove from heat; let steep for 15 minutes. Strain honey syrup through a fine-mesh strainer; discard jalapeño.
In a large pitcher, muddle pineapple and sliced jalapeño. Stir in honey syrup, pineapple juice, and lime juice until well combined. Cover, and refrigerate for at least 1 hour or until ready to serve. Just before serving, stir in beer. Divide mixture among 6 glasses filled with ice. Garnish with jalapeño and pineapple, if desired.
