While the Death & Co. glass is a premium tool known for its quality, any sturdy mixing glass or even a robust pint glass will work. The primary goal is a vessel that allows for efficient chilling and easy straining, ensuring your cocktail is perfectly cold.

For the best and most authentic flavor profile in a Hemingway Daiquiri, fresh-squeezed lime and grapefruit juices are essential. Bottled juices often contain preservatives and lack the bright, fresh acidity needed, which can significantly diminish the cocktail's quality.

This usually happens if you're not using enough ice or shaking vigorously enough. Ensure your shaker is packed full with fresh ice and shake hard for at least 15-20 seconds until the shaker feels frosty, ensuring optimal chilling and the right amount of dilution.

Double straining involves pouring the cocktail through both your shaker's built-in strainer (or a Hawthorne/Julep strainer) and a separate fine mesh strainer. This extra step removes all small ice shards, fruit pulp, and any other solids, resulting in a perfectly smooth, clear, and elegant drink.
