The flagship beer of the Mill Street Brewery Ottawa Brewpub is a cream ale that pours a slightly pale golden colour with a frothy white head that leaves a healthy amount of lace behind as it settles and gets retained as a thin, collared cap. Portage Ale smells mostly of sweet grains, wheat and yeast. There is a strong juice-like tone that hovers between raspberry, cherry and grape, and a slight hint of alcohol on the nose.
The taste of Portage Ale is rather sweet as well, with grains making up the bulk of the body. There is a strong grassy tone, a certain grape or apple juice-like flavour, as well as subtle milk chocolate and red berry notes. The ale is medium-bodied with a high carbonation level and is quite creamy on the tongue thanks to a distinct yeast character. The finish is dry and the aftertaste has lingering yeast and raw grain tones.
