This study evaluated the effect of Hibiscus sabdariffa (HS) (Malvaceae) calyces on fermentation kenetics, phytochemical constituents, volatile organic compounds (VOCs) and sensory profile beer. Single infusion method mashing was utilized, resulting beers were compared to industrial beers. HS supplementation did not alter kenetics as a general decrease in extracts (oBrix) observed treated contro...

9 A surprising phenomenon witnessed by many is the sinking bubbles seen in a settling pint of 10 stout beer. Bubbles are less dense than the surrounding fluid so how does this happen? Previous 11 work has shown that the explanation lies in a circulation of fluid promoted by the tilted sides of the 12 glass. However, this work has relied heavily on computational fluid dynamics (CFD) simulations....
