Thanks Chris :)

You may find this article about the commercial trifecta interesting.

But did you see the comments to that article?  Yowza, I think I've about had it with the "hipster" snarf comments that keep turning up every time I read a third wave coffee establishment review!

Sorry about the thread-jacking, Amanda.  Love my trifecta MB.  Love what Bunn is doing these days...

"Hipsters!"  Where do these yahoos come off?  Anytime something costs more, it's hipster this and hipster that.

Breathe... inhale, exhale, nice and slow.

Seriously, Amanda, love the product.

Well, new problem this morning. I think this one will require the unit to be shipped back to be looked at.

Today during pressout I heard a strange snap sound. And the press didn't seem to have alot of pressure behind it. When it was all done, the cup looked not full enough. The brew chamber had maybe about a quater of the water remaining in it, just soaking grounds. Maybe my issue has been the pressure system all along? I cant believe Ill have to go without my Trifecta Brew for awhile! Back to pourover I suppose till this gets ironed out.

Spoke with Amanda on the phone yesterday, and for now it appears everything is fine. The best guess it that for some reason it went over pressure. Sounds like it could be the grounds, type and grind level. Got home and everything worked fine again.

Customer service is great, thanks for taking some time to talk to me about this Amanda.

Glad to hear it, Chris.

I should mention (finally) that about a month ago my Trifecta went through a moody period during which I was getting a bunch of incomplete press-outs. Here's a list of things that didn't help:

- Coarsened up my grind somewhat on two different grinders (Preciso and Orphan Espresso LIDO)
- Removed the black shower head gasket, cleaned it, flipped it, and reinstalled
- Removed the shower head cover plate, removed and cleaned out both check valves, then reinstalled
- Replaced the check valve underneath the brew chamber
- Descaled
- Replaced both check valves in the shower head

Interestingly, throughout this little episode I was having better luck with 8-oz. brews than with my usual 10-oz. cups (all on C-:50); the latter tended to end with that telltale puff of air escaping from the top of the brew chamber.

I went through some troubleshooting with Amanda and even got to the point of asking for (and receiving) a prepaid shipping label, but in the end I didn't send the machine in because the problems I'd been having more or less went away when I moved on from two coffees I'd been using. Maybe I hit upon a particularly dense batch of beans? Not sure. FWIW the troublesome coffees were a natural-processed Counter Culture Rwanda and (most of all) a strictly high grown Topeca El Salvador (http://store.topecacoffee.com/sa12.html). Since I ran out of them, I've only ended up with a slightly wet brew chamber following press-out a few times, and in each case there's been much less coffee retained than before.

I'll hang on to the shipping label as a precaution, but for now it seems I'm out of the woods.

I don't seem to be having these problems.  I do a water-only brew every other brew cycle.  And I never grind finer than drip (probably a little coarser).  Also, I enjoy medium roast coffees or (much less often) medium roast blended with darker roast.  Could that be why?


P.S. Murphy's Law dictates that I will now start having these problems right after I post this.  Thanks a lot, guys.

Well, I ended up removing all the valves you can get to, and giving them all a quick 5 minute vinegar bath. I think Ill make this a monthly ritual. Combined with the vinegar run every 10 days or so. I do have hard water out here.

I dont know if it had any effect or not, but everything is fine now. I am still using the same coffee, home roasted to Full City+.

Michael, the water-only cycles didn't seem to help in my case, so cleanliness of the metal filter probably isn't it. Since I'd been using the same grind for months with no incidents across many, many coffees, I don't think that was the problem either. In fact, at one point I went all the way to a press grind on A-2:00 with the El Sal I mentioned and still got an incomplete press-out. Re: roast, I'm always on the light-medium side. At the time my $$ was on the shower head as the culprit, but it's all academic now since the MB is behaving again. Hope you didn't jinx yourself!

Hi guys, recently purchased a Trifecta and I've got a Vario-W on the way. I received the counter culture monthly single origin subscription coffees which were tasty as usual. Does anyone have other specific counter culture favorites with the trifecta? if so, what brew settings do you use? also, those of you with Vario-W's, what grind setting are you using? Thanks for the help!

I haven't personally had any Counter Culture coffee but I will need to check it out (I personally order from Cuvee Coffee currently).  As far as settings - I typically use :45 for all my coffees, unless I want a little more body which I will go up to :50.  I personally prefer my coffees more acidic - and for Ethiopian blends (which are currently my favorite) I will do either a turbulence of A or B, for most other coffees do a turbulence of B or maybe C, and sometimes just for fun will occasionally do D.  Really, it comes down to what you prefer.  Some people just leave it at a particular setting for every coffee - but I find I have more fun if I constantly switch it up.

As far as the Vario-W goes I have both the macro and micro levers all the way to the coarsest settings.  It seems everyone who has the trifecta MB and the Vario-W recommend the steel burrs since you can go coarser, get a lot less fines, and get more flavor.  I've yet to pull the trigger on replacing the burrs but I have a feeling I will eventually do that soon.

Thanks for the feedback. When I ordered the Vario-W, I upgraded to the steel burrs based off what I read on this forum. Those of you with steel-burrs in the Vario-W, are you using the coarsest setting on both micro and macro adjusters? Thanks again.
