“Obsv” is a specific designation used by Four Roses to describe one of the recipes for their bourbon. Each letter in the code represents different characteristics of the whiskey, giving consumers a glimpse into what they can expect from that particular expression.
In the case of “Obsv,” the “O” signifies that the bourbon is from Four Roses’ distillery. This is important because Four Roses has two different distilleries, and each one produces bourbon with its own unique flavor profile. So, when you see “O” on a bottle of Four Roses bourbon, you know it’s coming from their original distillery.
Moving on to the next letter, “B,” this represents the mash bill or the ratio of grains used in the bourbon. In this case, “B” indicates that the mash bill is made up of 60% corn, 35% rye, and 5% malted barley. This specific combination of grains contributes to the overall flavor and character of the bourbon.
Now, let’s delve into the third letter, “S.” This letter tells us that the bourbon is classified as straight whiskey. Straight whiskey has specific regulations it must meet, such as being aged for at least two years in new charred oak barrels. So, when you see the “S” designation, you can be assured that the bourbon has met these criteria.
Lastly, we have the letter “V,” which represents the yeast strain used in fermentation. Four Roses utilizes five different yeast strains, each with its own distinct characteristics. In the case of “V,” it stands for Delicate Fruit. This yeast strain imparts a delicate fruity flavor to the bourbon, adding another layer of complexity to the final product.
By decoding the “Obsv” designation, we can gather that the bourbon is from Four Roses’ original distillery, has a mash bill consisting of 60% corn, 35% rye, and 5% malted barley, is classified as straight whiskey, and is made with the Delicate Fruit yeast strain, providing it with a unique and fruity flavor profile.
It’s important to note that this is just one of the many recipes Four Roses uses to create their range of bourbons. Each recipe offers a different combination of grains and yeast strains, resulting in a diverse portfolio of flavors to cater to various preferences. Exploring the different recipes is a delightful journey for bourbon enthusiasts, as it allows them to discover their own favorite expressions within the Four Roses lineup.
