Billy Carmen from Product News Channel at Interbike with Christian from BRUBAR all natural vegan energy bars. BRUBAR Energy Bars are all-natural and vegan with a focus on a malty flavor with a smooth texture. We are able to focus on this malty flavor because, unlike other energy bars, our main ingredient is barley malt. Because barley malt is not as sweet as other sugars, we can add a lot of it without making the bar too sweet. This gives the bar a smooth taste and a moist texture. The recipe was kept simple, with only a handful of natural ingredients that contribute to the overall flavor and function of a BRUBAR Energy Bar..
