Aroma – Prominent Northwest variety hop aromas – resinous pine, citrus, sweet malt, hints of roast malt, chocolate and/or Carafa®, can include mild coffee notes, dry hopped character is often present.
Appearance – Deep brown to black with ruby highlights. Head varies from white to tan/khaki.
Flavor – A balance between citrus like and spicy Northwest hop flavor, bitterness, caramel and roast, chocolate, or Carafa® type malts. Any roast character should be subdued. Black malt is acceptable at low levels but should not be astringent. Any burnt character is not appropriate. The finish should be dry with caramel malt as a secondary flavor. Diacetyl should not be present. The main emphasis should be on hop flavor.
Mouthfeel – Light to medium, hop bitterness and tannins from roast malts combine to create a dry mouthfeel. Resinous character from high levels of dry hopping may create a tongue coating sensation.
Comments – Some brewers prefer to cold steep the dark grains to achieve a very dark beer without the tannin contribution of adding these grains to the mash. The use of Sinamar® color extract to enhance the color is common.
The article itself, which you can read here, then goes on to explain how ASIBA is different from a hoppy stout or porter, but I personally am unconvinced. Therefore I have decided to try an experiment with an upcoming homebrew project. I am going to take one of the clone recipes provided with the article, leave the malts alone by and large, but substitute the hops with British varieties such as Challenger, Target and Northdown. As of this moment I am undecided as to whether to stick with an American yeast or use a British ale strain of some kind.
If I discover that indeed ASIBA is significantly different from a traditional porter, then I would like to believe that I will have developed a new beer style to revolutionise the world of brewing, the British Style American Style India Black Ale! I am sure the world waits with bated breath.
