How should you adjust the grinder if shots are pulling too slow?

When shots are pulling too slow, it indicates that the coffee grounds are too fine, causing water to take longer to pass through them. To remedy this situation, you need to adjust the grinder to create a coarser grind.

Making the grinder pull faster is synonymous with adjusting the grind to be coarser, which can be accomplished by turning the grinder 1/4 turn clockwise. This adjustment allows more water to flow through the coffee grounds more quickly, helping to achieve a proper espresso extraction. The goal is to find the right balance for an optimal shot, which should typically take around 25-30 seconds to brew.

The other options provided do not address the issue of grind size effectively or are not practical measures for solving the problem of slow shot pulls. For example, reducing brew time doesn't actually correct the grind size issue, and adding ice would alter the beverage's temperature and could negatively affect flavor. Hence, adjusting the grind setting to be coarser is the correct action to take.
