This beer was developed through extensive experimentation by our brewers with different combinations of dried fruits and spices, using Basis as the base beer. Iridescent is a refreshing blonde sour ale, with aromas of apricot and ginger that are followed by tart and tropical flavors after aging in wine barrels for 3-4 months. As the name implies, the flavor of this sour beer appears to change subtly with each sip.
