When it comes to choosing the right size flask, it ultimately depends on your personal preferences and needs. However, the most common flask size that you'll come across is 8 ounces. This size is popular because it strikes a balance between portability and capacity. It's important to note that an 8-ounce flask can hold approximately 5 shots of liquor, which is a decent amount for most casual occasions.
Now, let's talk about carrying your flask. While it may seem fashionable to keep it in the back pocket of your trousers, this can actually have a negative impact on your whiskey. The body heat generated from sitting can warm up the flask and consequently, the whiskey inside. This can affect the overall taste and experience of enjoying your drink. So, if you're someone who appreciates the nuances of whiskey and wants to ensure it stays at an optimal temperature, it's best to carry your flask in an inside jacket pocket.
By keeping the flask inside your jacket pocket, you're providing it with some insulation from external heat sources and body heat. This helps to maintain a cooler temperature for your whiskey, allowing you to enjoy it as it was intended to be. Of course, if you're not too concerned about the temperature of your drink or if you're in a social setting where style takes precedence over the optimal drinking experience, then feel free to carry your flask however you prefer.
In my personal experience as a sommelier and brewer, I've found that carrying a flask in an inside jacket pocket has been the best choice for preserving the quality of the liquor. There have been occasions where I've kept a flask in my back pocket, only to find that the warmth has affected the taste and overall enjoyment of the drink. Since then, I've made it a habit to always carry my flask in an inside pocket, especially when I'm attending events or gatherings where I want to savor every sip.
To summarize, the most common flask size is 8 ounces, which can hold approximately 5 shots of liquor. Carrying your flask in the back pocket of your trousers may seem cool, but it can warm up your whiskey due to body heat. If you're someone who cares about maintaining the optimal temperature and taste of your drink, it's best to carry your flask in an inside jacket pocket. However, the choice ultimately comes down to personal preference and the occasion at hand.
