Opinion Alert!
Below is
my opinion and you may have a different one.
You are not likely to change mine, I'm too old for that, but please don't hesitate to express your own. That's what dialogue is for.
Isn't Black IPA an oxymoron to begin with? How can something be Black and Pale at the same time!
Black Ale would be fine, but then if color is the only attribute being called out as a differentiator then why bother?
You can't taste "black", you can taste toasty or roasty, but not "black".
So what is the point anyhow, in my opinion it is purely marketing BS.
Which brings up the total BS of a canned "Black and Tan"! Is a good stout too much for some (BTW I do not consider Guiness to be a good stout necessarily)? Or is the ale or lager blended unable to stand on its' own merit so it needs a stout to fill-in some flavor gap?
Again why bother? It's like putting a wedge of lime on a corona. That is obviously to compensate for a total inability of the brew to stand on its' own. Don't add fruit to my beer at serving time. If that's how you brew it fine, I'll judge if I like it based on taste.
If you can't draw a pint at the intended serving temp and take a sip and think "man that is a good beer", it aint worth drinking!
And as for beverages that rely on a particular "look", if it doesn't taste better (Black and Tan) don't bother offering it to me.
If I want visual stimulation I'll look at art or a beautiful creature. That's not what I open a beer for.
Rant off, Opinion stated!
To the OPs initial post; Let's hope so, there's better use for commercial shelf space.
