Taste impact of pulling into shot glass then transferring to cup for milk drink?

Postby jeffg on Fri Nov 02, 2007 6:40 am

Just a curious question about how much this impacts the final product. I am not worried about visually, just taste wise. Since I am still learning I find it helpful to pull my shots into a pre-heated, measured pyrex shot glass. Once the shot is poured i grab my milk, froth (done in 20secs on my machine), then i pour my shot into a pre-heated cappuccino cup, add the milk. It doesn't seem like this would be a problem but who knows it could be a big no-no. I suspect pouring direct into the cup keeps the crema more intact and allows the crema to then form a nice tasty ring around the top when pouring milk.

I really don't think you're hurting anything as long as you enjoy the drinks you're making. I will commonly stir my shot before adding milk (if using milk). I just don't like the taste of crema. I want to see it when pulling so I know my beans are fresh, but as far as in the cup I really don't want much of it. I also prefer lower extraction pressures as this has smoothed the flavor intensity for me and by default produces less crema. But to each their own (you see I guess we both break the rules)! :wink:

I wouldn't expect a dramatic change in the taste profile, especially given the recent admonishments at barista competitions to agitate, swirl, or even "flip" the espresso before drinking. From SCAA Barista Competition - USBC 2007:

ThePete wrote:I'm glad you asked Dan. Luca is pretty right on with what he said. Espresso is a layered drink when you think about it, and "flipping" the shot is something that we at PT's came up with especially for tasting at the barista competition this year. If you haven't done it before try pulling a shot between 3 separate shot glasses filling 10ml in each until the extraction is done. If you taste them, you should find the first 10ml to be very sweet and heavy, second hits more acid and body, and third is quite thin in comparison with more of the floral and bitter notes. Now think about how the shot pours and you see that the thin, less preferable flavors are in the first sip. I have to thank our roaster Marty Gish for the initial idea for flipping the shot. Back to your actual question, we did have issues with losing crema points when practicing this method. What it came down to in my mind is speed of service. You don't want your shots to sit anyway, but just stepping up my haste helped preserve the color and persistence of crema. In fact, one of my judges in the finals wrote "great crema!" on my score sheet. So in my opinion, the gain on the flavor side completely outweighed a very small loss if any on the crema components. I would encourage everyone to try the "PT's flip" as we have been calling it. Pull a double shot, one straight into a demi and the other into a preheated shot glass and pour it into a second demi and try them side by side. Doing a blind tasting is even better. You might just be amazed that both shots, especially on that first sip, came from the same portafilter. On a final note, I don't feel that this is a step that should always be done especially at a cafe. As I said before, espresso is a layered drink and I find that part of the enjoyment is tasting the changing flavors as you drink it down.

That said, swirling isn't attracting many adherents, according to the poll: Do you mix / stir your espresso before drinking it? I'm a "sometimes swirls" drinker, e.g., if the espresso has a good start but an edgy finish, I'll swirl in hopes of evening it out.

Unless you have eccentric tastes, like TimEggers, or an ultra-sophisticated "flip" flavor goal, like PT's, the only reason to use a shot glass or "transfer pitcher" is that your cappuccino cup doesn't fit under your spouts. Your goal should be to preserve crema and save preparation and cleanup steps. Crema is not just a sign of fresh beans; for most people it's one of the main pleasures of espresso.

When you see a shop using those little transfer pitchers, it's usually an indication of poor training and a warning that you are about to receive a subpar drink.

Marshall is spot on.

Crema plays a huge part in the mouthfeel and flavor of the espresso. Missing the crema is losing one of the primary layers of the espresso. Crema retention equals flavor retention, and if you lose a significant portion of your flavor it will certainly impact the cup. It's debatable whether it is the most crucial or not, but as I see it, you need all the elements in the cup whether for a shot or pulled for a milk drink. Try making your cappuccino both ways, and see what you taste.

Oh no don't do that, there is after all only one "right" way! :roll: :wink:

I should add that the only time I stir the shot is when the extraction is a little off (I never claimed to be a good barista). But when the extraction is spot on I enjoy the drink as is. Honestly guys to each their own.

Everyone is entitled to their own preferences, even if they are eccentric. I have plenty of eccentricities of my own.

But, in this editor-free world of the Internet, we really do a disservice to newbies if we don't warn them when the advice we are about to give is far off the norm and based on an unusual taste preference.

that has certainly been my experience, with the caveat that the overwhelming majority of espresso drinks one gets in randomly selected cafes outside of Italy would fit that description, regardless of the techniques they use.

I completely agree sir. I would like to see more emphasis on the Internet for traditional methods as well. How often is it taught that espresso can be simply grind, dose, and level, tamp then pull? I fear not often enough.

Ah, yes. My own hobby horse.
