Some berries are known for their particularly high acidity, which gives them a sharp, tart flavor. Cranberries are a prime example, possessing one of the lowest pH levels among common berries. This high acidity is the reason they are often sweetened extensively when processed into juice or sauce. Redcurrants and gooseberries also fall into the highly acidic category. For individuals with acid sensitivity, these berries, and especially their concentrated juices, should be consumed with caution.
