Is it a smoothie? Is it a beer? Something to make the beer purists’ skin crawl? Sure, all of those, we suppose. Brain Freeze is fruity, creamy, tart and dreamy – what we’re calling a smoothie sour. This edition mixes strawberry and pineapple together with a whole bunch of lactose and vanilla with a pinch of gray sea salt and has a well-rounded tartness from a newly developed sour culture that brightens and enhances the complex fusion of flavors in this juicy style bender.
