CellarScience – HAZY New England Ale Yeast x 12g

CellarScience HAZY New England Ale Yeast 12g is a specialised ale yeast developed for brewers who want to maximise hop aroma, tropical fruit character, and the signature haze associated with modern New England-style beers. Designed specifically for hop-forward recipes, this yeast enhances juicy hop expression while contributing its own distinctive ester profile.

The flavour profile of CellarScience HAZY New England Ale Yeast 12g features vibrant notes of peach, citrus, mango, and passionfruit. As a result, it works exceptionally well with modern hop varieties such as Citra, Mosaic, Galaxy, El Dorado, and Nectaron. The yeast promotes the soft, juicy character that has made New England IPAs one of the most popular beer styles in the world.

One of the key advantages of CellarScience HAZY New England Ale Yeast 12g is its ability to maintain the hazy appearance that brewers expect from the style. Its medium-low flocculation helps keep hop compounds and proteins suspended in the finished beer, creating the attractive haze and smooth mouthfeel associated with premium NEIPAs.

Every batch undergoes PCR testing to ensure contamination-free yeast and consistent fermentation performance. Furthermore, the yeast is produced using an advanced aerobic growth process that allows direct pitching without the need for oxygenation during the initial stages of fermentation.

Whether you’re brewing a juicy New England IPA, Hazy Pale Ale, Tropical IPA, or other hop-forward beer style, CellarScience HAZY New England Ale Yeast 12g delivers exceptional fruit character, reliable fermentation, and the haze modern craft brewers love.

Direct Pitch Method

1. Cool wort to the desired fermentation temperature.
2. Sprinkle the yeast directly onto the wort surface.
3. No oxygenation is required during the initial fermentation stage.
4. Ferment within the recommended temperature range.
5. Allow fermentation to complete before conditioning and packaging.

The advanced aerobic growth process produces high sterol levels and excellent viability, making direct pitching simple and effective.

Rehydration Method

While direct pitching is recommended, rehydration can also be used.

1. Sanitize the yeast sachet and scissors.
2. Prepare sterilised water at 29-35°C.
3. Use 10g of water mixed with 0.25g of FermStart per gram of yeast.
4. Sprinkle yeast onto the water surface.
5. Allow to stand undisturbed for 20 minutes.
6. Gently swirl to form a slurry.
7. Adjust slurry temperature to within 6°C of wort temperature before pitching.
