Certainly the best coffees I've had this year would have been unsuitable SO in barista competition, since they either had too much crema color variation or didn't taste right at the prescribed measure and time.
My (very selfish) standpoint is that these competitions should ideally showcase the best espresso SOs and blends conceivable. The rules should be constructed to permit this.
I don't disagree. The idea of having the same SO supplied to each competitor would indeed require rules changes, not only in prescribed volume and time but quite likely removing the ban on adjusting espresso machine temp or pressure. I don't know if the rule is standard for all SCAA comps but the stated NWRBC calibrated shot temp
standard seems to me pretty wide 195-205f. I don't know if a competitor is allowed to have their station's machine adjusted to their desired shot temp during prep time but doesn't seem so. Unless not being their ideal shot temp would be considered under a "technical problem".
The SO idea could be something along the lines of Iron Chef America were the competitors are given three possible "secret ingredients" in advance. They find out which one of the three is to be used competition time. In this case given three possible SO's with roast profile for each specified. Sure without advance samples of the exact SO lot and roast they'd have to rely on their knowledge of similar SO's, but seems that's part of testing coffee knowledge. Seems appropriate they would be supplied the exact SO during prep time to dial it in, including adjusting espresso machine if deemed needed.
Now the problem of espresso machine setup for SO not being ideal for their blend...another technical issue to work out. IIRC some commercial multi-group machines allow individual group temp settings but don't believe the LM GB5s being used at NWRBC would. And expanding grinder limit from two to three, but that one is easy.
Hey I'm not saying SO shots
should be added to SCAA Barista competitions, just thought it would be another barista skill challenge. And from time limitation constraints maybe totally impractical. Not referring to current prep and comp times which would have to be increased accordingly, but simply the time it would add to the overall competition.
