An American IPA with deep citrus and grapefruit aroma, malty backbone and a relaxed bitterness What’s with the name? A flip switch is a mechanism actuating the transition between open and closed states of an electrical circuit. Probably the most common example is a light switch. You know that intense bright light you get when you flip on a good old fashioned light bulb? The kind that almost blinds you until your eyes have a second to adjust? Well the bold hop flavor you experience in the first sip of a Flip Switch is kind of like that, without the blindness of course.
