Currently taking 25mg metoprolol tartrate and 10mg crestor (rosuvastatin). Is it harmful to dring alchololic beverages while taking these meds?

OK. As long as your liver blood tests are normal, a moderate amount of alcohol is ok while on those medications.
OK IN MODERATION. Moderate amounts of alcohol should be fine on these medications. Moderate amount of alcohol would be two alcohol servings per day for a man and one alcoholic drink per day for a woman.
