# numberOfAlcoholicBeverages A quantity sample type that measures the number of standard alcoholic drinks that the user has consumed. ``` static let numberOfAlcoholicBeverages: HKQuantityTypeIdentifier ``` ## Discussion Samples matching the [`numberOfAlcoholicBeverages`](/documentation/HealthKit/HKQuantityTypeIdentifier/numberOfAlcoholicBeverages) identifier measure the number of standard alcoholic drinks consumed by the user. A standard drink is one beer, glass of wine, or mixed drink made with spirits. The samples use count units (described in [`HKUnit`](/documentation/HealthKit/HKUnit)) to measure cumulative values (described in [`HKQuantityAggregationStyle`](/documentation/HealthKit/HKQuantityAggregationStyle)). The following code listing saves a single standard drink to the HealthKit store. ```swift // Create the alcoholic beverage sample type. let alcoholConsumptionType = HKQuantityType(.numberOfAlcoholicBeverages) // Create a quantity for the number of standard beverages consumed. let beverageCount = HKQuantity(unit:HKUnit.count(), doubleValue:1.0) // Get the current date. let date = Date() // Create the alcoholic beverage consumption sample. let beverageSample = HKQuantitySample(type: alcoholConsumptionType, quantity: beverageCount, start: date, end: date) // Save the sample to the HealthKit store. store.save(beverageSample) { (success, error) in if success { // The system successfully saved the sample. } else { if let error = error { // Handle the error here. } } } ``` --- Copyright © 2026 Apple Inc.
