Here's my take.
Most pour over is poor, over and over and over again. Especially V60. You're better off with a beehive dripper or an older style three to five hole Kalita filter pour over. The majority of barista, including those in known shops, are not very skilled when it comes to pour over. Too fast. Improper grind. Improper extraction. You can't rush the process. For many of these shops, whether pour over, siphon, Chemex, etc., it's about "the show".
I remember when I went to speak at the SCAA in 2011 and I have never had so much improperly brewed pour over in my life. Vince Piccolo, head of 49th Parallel Coffee, said to a group of us to remind him to never have pour over at these events again. It was that bad.
So... consistency of batch brewers. Yes, much better than most barista. But an average shop, or an average shop who believes they are a "high end" shop would not or should not be doing pour over.
Redswing,
to the comment just made about having a large brewing system and then offering pour over.... bad, bad, bad idea. This is something we specifically talked about at the SCAA. You can't have both. Either you are an artisan quality shop that brews by the cup or you are not. A tiered system does not work. You brew by the cup because you are confident that it provides a better cup, and better service (this coffee was made just for you!). Single cup brewing is not for everyone. But having both sends mixed messages to both your staff and your customers. As Kyle Glanville said during his part of our presentation,
"Batch brewing in conjunction with by-the-cup will force by-the-cup to take a back seat. - Kyle G."
And what about pricing? Coffees served? You certainly would not have your best coffees batch brewed. And there needs to be a big difference in pricing. It's not always for the coffee. It's for the skill it takes to make it properly. And in my opinion, once any artisan by the cup coffee is served in a paper cup, it completely devalues that coffee. It should not just be a brewing method. It's an experience from start to finish, and in order to give the customer the greatest value, you have to care enough to spend time with them, and with the coffee. Share in the process. Share in the experience. Create something magical.
I've been doing siphon since 2007/2008 (when we installed our bar). Always in house, black, and served in ceramic. We started at $6 per cup and up, and now range from $8-$12 per cup (more for CoE or Gesha, etc.) I've brewed 8000+ cups on siphon, and I know what does and does not work... but you have to be fearless. You have to be "all in".
As far as single-cup brewing goes, the notion that it can't work is just not so. The most successful "by the cup only shops" only do it "by the cup". You have to change your paradigm. And it's certainly easier if it's something you are adding rather than taking away something else. If you want to do by the cup, don't ever offer batch brewed. It's that simple.
