Final answer:
If espresso shots are taking too long to pull,B) adjust the grinder to make the coffee grinds finer.
Explanation:
When espresso shots are pulling too slowly, it typically indicates that the coffee grounds are too coarse. Finer grounds allow water to pass through more quickly, resulting in a properly timed shot. Adjusting the grinder to make the coffee grinds finer will decrease the extraction time and produce a better-quality espresso. This adjustment should be made gradually, testing the shot timing after each change until the desired extraction time is achieved.
B) Adjusting the grinder to make the coffee grinds coarser would have the opposite effect, prolonging the extraction time. Flushing out the espresso heads or tamping more firmly are unlikely to address the issue of slow shots caused by grind size. While these actions can sometimes help improve extraction, they are not the primary solutions for resolving prolonged extraction times. It's essential to understand the relationship between grind size and shot timing to troubleshoot espresso extraction effectively.
