Although its name suggests otherwise, the szechuan pepper is not a real pepper, but a distant cousin of the citrus fruit. For this beer, the red version was used, which has a slightly fruitier flavour than the green and provides a slight tingling effect on the aftertaste.
Other than that, citrus aromas and a certain spiciness emerge. The refermentation in the bottle provides the necessary minerality and balance, so the presence of the szechuan pepper is not overwhelming.
