The great new debate: 49mm vs 58mm portafilter baskets

The world of specialty coffee is always evolving, with enthusiasts and professionals alike constantly seeking the perfect brew. One of the latest discussions in the coffee community revolves around the use of 49mm versus 58mm portafilter baskets. This debate has been fueled by insights from coffee expert Lance Hendrick, who has explored the nuances of both sizes in his recent videos. Let's dive into the key points of this discussion and understand the implications for your espresso experience.

Understanding Portafilter Sizes

Portafilters are essential components of espresso machines, holding the coffee grounds during extraction. The size of the portafilter basket can significantly impact the quality and characteristics of the espresso shot. The two most common sizes are 49mm and 58mm, each with its own set of advantages and challenges.

The Case for 49mm Portafilter Baskets

Lance Hendrick's exploration into 49mm portafilter baskets reveals several compelling reasons to consider this smaller size:

1. Deeper Puck, Coarser Grind: The 49mm baskets allow for a deeper coffee puck, which can be ground more coarsely. This results in a more efficient extraction and often leads to tastier shots.
2. Consistency and Balance: Smaller diameter baskets tend to provide a more balanced representation of the coffee, maintaining the piercing acidity and florals without losing balance.
3. Innovation and Adaptability: With the rise of innovative solutions like Sheldon Wong's step-down baskets and conversion kits, it's easier than ever to experiment with 49mm baskets on machines originally designed for 58mm.

The Traditional 58mm Portafilter Baskets

Despite the advantages of 49mm baskets, 58mm remains the industry standard, especially in commercial settings. Here's why:

1. Historical Precedence: The 58mm size has been used in commercial espresso machines for decades, primarily because it was manageable in service settings and allowed for efficient beverage preparation.
2. Accessory Availability: The widespread use of 58mm baskets means there is a plethora of accessories available, making it easier for baristas to find compatible tools and upgrades.
3. Perceived Quality: Many coffee enthusiasts believe that the larger surface area of 58mm baskets leads to better extraction and more even shots, although this is increasingly being challenged by new research.

Lance Hendrick's Findings

In his videos, Lance Hendrick conducted experiments comparing the two basket sizes using the same coffee and extraction parameters. His findings were intriguing:

• Extraction Efficiency: Despite the smaller diameter, 49mm baskets often resulted in higher or comparable extraction yields compared to 58mm baskets.
• Taste and Texture: The 49mm shots were consistently described as having better mouthfeel, less bitterness, and more balanced flavors.
• Workflow and Practicality: While 49mm baskets can be more challenging to work with due to their depth, the innovations in basket design and conversion kits have made them more accessible.

Product Recommendations

For those interested in experimenting with different portafilter sizes, here are some product recommendations:

1. Sworks 49mm Step-Down Basket: A versatile option for those looking to try 49mm baskets on their 58mm machines.
2. Sworks Conversion Kits: These kits allow you to easily switch between 49mm and 58mm baskets, offering flexibility and innovation.
3. IMS Precision Baskets (Affiliate Link): Available in both 49mm and 58mm sizes, these baskets are known for their high-quality construction and consistent performance.

Conclusion

The debate between 49mm and 58mm portafilter baskets is far from settled, but it's clear that both sizes have their unique advantages. Whether you prefer the traditional 58mm for its historical precedence and accessory availability or the innovative 49mm for its deeper puck and balanced extraction, the choice ultimately depends on your personal preferences and brewing style. As many of our readers are using a La Marzocco Linea Micra or La Marzocco Linea Mini R, the new hybrid portafilter won't be compatible with the higher 49mm baskets (if used with the spouts).
