What makes a quadruple IPA?

Answered by Louis Krause

When it comes to defining what makes a quadruple , there are a few key characteristics that can be relied upon. As an expert sommelier and brewer, I have had the pleasure of exploring and experiencing the world of craft extensively. Quadruple IPAs, also known as “quads,” are a unique and powerful style of beer that push the boundaries of traditional IPAs.

One defining feature of quadruple IPAs is their extreme hop content. These beers are often brewed with a staggering amount of , typically ranging from 7 to over 10 pounds per barrel. This abundance of hops contributes to the intense and robust hop flavors and aromas that are characteristic of quads. The hops used can vary, but popular choices include Citra, Mosaic, Simcoe, and Amarillo, among others. The combination of these hops creates a bold and complex hop profile that sets quadruple IPAs apart from their counterparts.

Another notable aspect of quadruple IPAs is their high by volume (ABV). These beers are known for their strength, often falling within the range of 10% to 15% ABV or even higher. This elevated alcohol content adds to the overall intensity and body of the beer, giving it a substantial and warming character. It's important to note that the high ABV in quadruple IPAs can have a significant impact on the flavor profile, with alcohol warmth and sweetness being more prevalent.

In terms of appearance, quadruple IPAs typically exhibit a deep golden to amber color, often with a slight haze. The substantial backbone in these beers helps to support the intense hop bitterness and provides a rich and robust base for the flavors to shine through. The head on a quadruple IPA can vary, but it is often creamy and persistent, adding to the overall sensory experience.

When it comes to flavor, quadruple IPAs are known for their intense hop bitterness and resinous qualities. The hop flavors can range from citrusy and tropical fruits to piney and floral notes, depending on the specific hop varieties used. The malt sweetness helps to balance the bitterness, creating a harmonious interplay of flavors. Despite the high alcohol content, the hops remain the star of the show, with their bold and assertive presence leaving a lasting impression.

It's worth noting that while quadruple IPAs share certain characteristics, there can be variations within the style. Some brewers may choose to experiment with different hop combinations or malt profiles, resulting in unique interpretations of the style. This diversity adds to the excitement and exploration of quadruple IPAs, as each brewer puts their own twist on this powerhouse style.

In my own experiences as a brewer and beer enthusiast, I have encountered a range of quadruple IPAs that exemplify the qualities I've described. From the explosive hop aromas that hit your senses as you crack open a can to the intense bitterness and warming alcohol on the palate, the experience of drinking a quadruple IPA is truly unforgettable. These beers are not for the faint of heart, but for those who appreciate bold and complex flavors, they offer a truly exceptional drinking experience.
