Being a purist
Beer should only be carbonated by it's own yeast.
FALSELY not forced carbonated brews are against real ale religion and are not Real Ale.
Nitro is blasphemy.
On the other hand, when pushing product everything goes out the window.
I can totally respect this stance, even if I don't entirely agree with it. In many but not all regards, both beer-related and not, I have puristic tendencies, and don't appreciate a lot of distracting items, with exception for sugar and fat... I love sugar and fat. Won't be dieting anytime soon, even if it kills me first. But I don't want any nuts in my chocolate or fudge, thank you very much. No extra flavorings. No berries on top of my cheesecake, I just like to eat it plain. However I'll take some real whipped cream on top, thank you. No Cool-Whip! I'll have a teaspoon of sugar in my coffee. Cream is fine but not necessary. Non-dairy creamer is right-out! And with respect to beers, yes, simplicity is usually best. Maybe not in every case, but usually. Oh wait, now here's one unpopular opinion!:
Beer-food pairings. What a bunch of malarky. When I drink beer, I only want the beer. Get that food away from me. I'll eat later. And the reverse is true as well. If I'm eating, I'll have a glass of milk or water or something. I'll have a beer later.
I don't believe that's a very popular one. But it's very true for me. One thing at a time is all I want.
