Usually they turn sweet as they ripen. So it is possible you are picking them a little too early. They need to stay on the bush until they are really ripe as they will not ripen any more after picking. You would pick them when they are fully colored and soft and juicy, at the last minute just before they turn overly soft. In other words, they are not really ripe until a few days after they turn a good blue. Some varieties are quite tart or sour until fully ripe, while others are maybe a bit less flavorful so you might not notice quite as much. Depending on the variety you have it could be between about 60 and 80 days after bloom, with the harvest lasting a couple of weeks. The berries in a cluster ripen over a period of time so you have to pick them one by one as they ripen, not all at once. Interestingly enough, the birds seem to know the exact day the blueberries are ready. So if you are not losing some to the birds you are probably picking too early. I hope this helps.
