Thank you for your question. The sweetness of berries is influenced by many factors, including precipitation, spring temperatures, soil, soil pH, nutrients and sunlight. Without knowing more about your environment, we are unable to identify which one or ones is a cause of your berries' sourness. Here is an OSU Extension publication about growing them on our coast: Hope this is helpful.
