In my experience as a sommelier and brewer, I have used both glass and metal cocktail shakers extensively. While both have their merits, I must say that the tin-on-tin shaker has proven to be the better option for several reasons.
1. Superior Seal: The most significant advantage of the tin-on-tin shaker over the glass-on-tin variant is undoubtedly the seal. The tight fit between the two metal tins ensures that no liquid escapes during the vigorous shaking process. This is crucial for maintaining the integrity of the cocktail and preventing any unwanted spills or leaks. On the other hand, glass-on-tin shakers often suffer from leakage issues, no matter how well you try to fit them together. I have found this to be particularly frustrating when preparing multiple cocktails simultaneously, as it slows down the process and creates unnecessary mess.
2. Durability: Another advantage of the metal shaker is its durability. While glass shakers can be fragile and prone to breakage, especially if accidentally dropped or mishandled, metal shakers are much more resilient. This durability is particularly important in a fast-paced bar environment where bartenders are constantly juggling multiple tasks and equipment. I have witnessed countless glass shakers meeting their untimely demise on the floor of a busy bar, resulting in both wasted ingredients and potential safety hazards.
3. Temperature Control: Metal shakers also offer better temperature control during the shaking process. The conductive nature of the metal allows for rapid cooling or heating of the cocktail ingredients, depending on the desired outcome. This is particularly advantageous when working with delicate ingredients that require precise temperature adjustments, such as egg whites or certain herbal infusions. Glass shakers, on the other hand, may not distribute heat or cold as efficiently, leading to inconsistencies in the final product. I have found that the metal shaker consistently delivers a more reliable and desired result.
4. Ease of Use: From a practical standpoint, the tin-on-tin shaker is generally easier to handle and manipulate than its glass counterpart. The smooth surface of the metal allows for a comfortable grip, even when the shaker becomes cold or condensation forms on the exterior. This ease of use is especially important when preparing numerous cocktails in quick succession, as it allows bartenders to maintain a steady and efficient workflow.
5. Aesthetic Appeal: While not a crucial factor in the functionality of a cocktail shaker, it is worth noting that the tin-on-tin shaker often possesses a more visually appealing aesthetic. The sleek and shiny surface of the metal exudes a sense of professionalism and elegance behind the bar. Glass shakers, although they can be visually appealing in their own right, may lack the same level of sophistication and durability that the metal shaker offers.
The tin-on-tin cocktail shaker has proven to be the superior choice in terms of functionality, durability, temperature control, ease of use, and aesthetic appeal. The tight seal and overall reliability of the metal shaker make it an invaluable tool for bartenders who strive for efficiency and consistency in their craft. While glass shakers may have their own charm, they often fall short in terms of practicality and durability in a fast-paced bar environment.
