What Makes a New England IPA Hazy

New England IPAs, also known as hazy or juicy IPAs, have become super popular in recent years. One of the defining characteristics of these beers is their cloudy appearance, which is often attributed to the high level of protein and hop particles suspended in the liquid.

Hop additions are essential in creating the hazy look for New England IPAs. Hops contain a variety of compounds that contribute to a beer’s aroma, flavor, and appearance. Essential oils from hops, such as myrcene and humulene, can contribute to haze formation.

During the brewing process, hops are added at different stages, including the boil, fermentation, and post-fermentation. The type and timing of these hop additions can affect the final haze level of the beer.
For example, late hop additions, which are added to the wort during the last minutes of the boil or during fermentation, can contribute to haze formation. This is because the essential oils in the hops are not fully boiled off and are instead carried over into the final beer.

Dry-hopping, which is the process of adding hops to the beer after fermentation is complete, can also contribute to haze formation. Dry-hopped beers often have a more intense hop aroma and flavor, as well as a hazy appearance due to the hop particles suspended in the liquid.

Another way to create haze is by using high-protein grains, such as wheat, oats, and barley. These grains can contribute to the haziness of the beer by providing more proteins to the wort.

But it’s not just about the hops, the yeast also plays a crucial role in beer fermentation, and the type of yeast used can greatly affect the final haze level of the beer.

Some yeast strains, such as London Ale III, Vermont Ale, and American Ale II, are known to promote haze formation. These strains have a high level of enzymes that encourage biotransformation and, therefore, break down hops and proteins more efficiently, which leads to a stable and opaque haze. They also tend to be low flocculation, which means they have a lower ability to form clumps and settle at the bottom of the fermenter, which helps keep the yeast and proteins suspended in the beer.

To sustain haze, it is essential to use yeast strains that are known to promote biotransformation and to carefully control the fermentation temperature. This will help the yeast to continue to work on breaking down the hops and grains, contributing to a stable haze in the final beer.

In summary, hop additions, biotransformation, and specific yeast strains play an important role in creating the hazy appearance that New England IPAs are known for. Late hop additions, dry-hopping, and using high-protein grains are effective techniques for adding haze. Yeast strains like London Ale III, Vermont Ale, and American Ale II, and low flocculation strains also promote haze formation. In contrast, proper yeast and temperature control will help create a stable haze in the final beer.
