Sounds like you are local. I'm in Surrey. As far as espresso quality goes, I enjoy what I get from my Brewtus at least as much as anything I've had at Artigiano. And a few years ago I thought that Artigiano was as good as it could possibly get. I don't claim that Brewtus espresso is as good as what can be achieved with a commercial machine. But just speaking as a consumer of the results, I never pine for a coffee house espresso when I'm drinking my home brew.
Beans: Until you get your grinder, Brewtus and technique set up to produce great espresso, I'd stick with only one brand. Once you get there you might find that the characteristics of the beans you start with are not quite to your liking and you can try something else. But trying to dial in the best parameters the first time while switching coffees seems like a bad idea, IMHO. Also, I don't know Coava but I found the sweet spot for Epic Espresso to be much smaller than for People's Daily. So I'd suggest starting with PD. Personal opinion based on my experience. But note that the two roasts are very different. Epic is much more acid and in your face which is not a bad thing at all and could be more to your preference than the more mellow PD. But it took me about 1/3 of a bag of Epic to get it dialed in. (Probably due to my incompetence. It was a good learning experience.) Naked Portafilter and VST Basket: I got both relatively recently -- 3-4 months ago -- and I'm a happy camper. My technique and the resulting espresso has improved a lot in that time. How much of that is due to the new accessories and how much is due to me just spending the time to learn and experiment, I don't know. But the VST at least looks beautiful if nothing else :-) I love the bottomless portafilter. It is fun to use and makes for easier cleanup. It definitely helps with identifying pretty much all problems associated with dosing, distribution, tamping and grinding. I bought my portafilter from EspressoTec in Richmond and my VST from 49th Parallel in Burnaby. The portafilter is generic E61 -- i.e. not specifically for the Brewtus. I found that it took several weeks for the new portafilter/VST combo to properly seal in the group head. In fact I almost switched to a thinner gasket but my procrastination paid off and it was just a matter of time until things were back to normal. Also, it is *very* difficult for me to remove the VST from the portafilter. The fit is very tight. I only ever remove it for serious cleaning so this isn't too much of a problem. The ridgeless version of the basket might have been a better choice for me. If I were you, I'd keep working on improving your espresso. It does take some time -- at least it did for me and I'm still learning, too -- but once you find the best techniques for you then consistency leads to no-brainer excellent espresso experience. One more thing. Do you make milk-based beverages? I wasn't happy with the steaming capabilities of the Brewtus. I raised the pressure to 1.1 from the initial 0.9 and that helped but I still only made average foam and with little consistency. Others here have raised the pressure to 1.4 and seem happy but my vendor warned me that anything above 1.0 was potentially bad and that made me cautious. Anyway, bottom line is that I bought a 12oz Espro Toroid pitcher and everything is now fine :D I can consistently make excellent micro foam and, finally, latte art. I bought mine at EspressoTec but I don't see it online so maybe they don't sell them anymore. They are made in Vancouver, though, and aren't that hard to find. These are all just my personal opinions and observations. I have a lot less experience and expertise than many in this group. So, I'm just saying, others will likely give you better advice but take heart that a n00b like me can make better than decent espresso with the Brewtus. peter On Thursday, June 7, 2012 1:04:02 AM UTC-7, gshokar wrote: > > I appreciate the responses Judge and pgs, your comments have renewed > my hopes in the machine.
