For example, not many would call a 5-6oz double cappuccino a "largish" milk drink. To put things in perspective, I make my wife 16oz skinny mocha lattes for b'fast - now
that's a "largish" milk drink!
<image>chocolate syrup melted over the foam while I was preparing the cappTry not to dismiss evidence that doesn't fit your new ideology, and assume that what works best for you will work best for everyone. If correct dosing is important for straight shots, then it's also important for cappuccinos. I have been experimenting with lower doses (14-16g) since you began these posts, and I'm getting good shots. But they haven't been noticeably better than my typical 16-18g doses. (Yes, I've sampled them as straight shots too.) And it's not because I want more coffee flavor for my "largish" milk drinks. I've played around with triple baskets, and prefer doubles, despite the fact that you can pack significantly more grinds in a triple. The reason I dose to 16-18g is simple: that seems to produce the best shot for me, with my roasts, on my equipment.
To eliminate dose as one of the crucial variables in espresso, and insist that only a 14g dose is appropriate, is just not worthy of your fine intellect.
Firstly, John, the second sentence in my post was intentionally NOT a dependent clause, but rather a separate sentence, because I was not commenting specifically on your preferred milk drinks as being "largish," rather commenting on what many do (obviously not you for your own consumption, as you have shown). For the record, my cappas are in the same size ballpark as yours. Nonetheless, one of the reasons why my one cappa, which often is my one and only milk drink of the day, is the first drink I pour, is that I can make a serviceable cappa with a mediocre shot, although not a sink shot. I use the experience with the first pour of the day, in the cappa, as a guide to how to adjust my grinders for their first straight shots later.
You have shown us pictures of your roasting set up, which in all honesty is not what I would call a standard roast set up. I have no knowledge of the characteristics of the roasted coffee that you get out it, and would never try to judge roasted coffee based upon pictures taken of the beans. You are obviously not alone in having a non-standard roast set up, and it could well be that nonstandard home roast setups are more the norm than the exception for home roasters. No doubt the characteristics of any particular home roasted coffee, especially coffee roasted in a nonstandard fashion, is going to be impacted by all sorts of coffee making and espresso making factors.
I may sound like I'm being evangelical, but in reality all I'm doing is trying to have a return to "normalcy" be viewed as the SOP (standard operating procedure). Anyone who makes 18 or 20g doubles knows how much effort you have to put into them in order to avoid channeling and other obvious problems that attend poor basket preparation and minor errors in grind setting. Anyone who has been to Italy and watched baristas over there is familiar with the cavalier approach that they take in shot making, and that they seldom if ever appear to pour shots down the sink. It is well known to anyone who has bought commercial grinders that the default setting on the dosers is around 7g per chamber. Now why is this?
Anyone who has used 18 or 20g doses who then switches to 12 or 14 or 15g doses can attest that their shots become much more uniform and that barring maybe an enormous error in grind setting, the espresso does not channel. Jim and many others have commented upon problems with various machines when baskets are overloaded and the coffee contacts the group screen. Why is that?
Putting all of this together, combined with well known and long standing Italian practice, it is pretty obvious that the equipment is designed for lower doses than has become SOP in N. America and for many internet aware home enthusiasts.
I'm not suggesting that 14g shots will necessarily be better than 18 or 20g shots. What I am suggesting is that if they are just as good as the updosed/overdosed shots, then what exactly is the point in using more coffee, other than force of habit and waste? If one finds an added benefit of achieving better "balance" in the 14-ish gram shots, than that is an added plus, something I have found but maybe others won't. I'd suggest that simply being "as good" at 14g, with less hassle, would be enough of a benefit to switch.
We haven't had much input from professional roasters in this thread, but I would caution the readers that it is kinda unlikely that a roaster, whose job it is to sell coffee, is going to advocate that we use a lot less of their product!
In any event, what I'd like to accomplish from this, over time, would be to have the standard basket dose recommended in internet land, to be more in accordance with what the machines were designed for, e.g. 12-15g, in my view. If someone wants to use more coffee, and figures out a way to do it that produces a better shot, than all I can say is, "that's terrific." As such, it
should be viewed as a
variation to standard technique, not
the standard technique.
