Froth Spectra | FT03 (Hazy / English Ale) BB: 20/11/2025

Explore the more delicate textures and indulge in a spectrum of radiant flavour & aroma. Spectra boasts a more robust attenuation capacity than many of its counterparts, while exhibiting an elegant ester profile and velvety mouthfeel. This prolific strain dances with hops & protein to offer a mesmerising glow in New England IPA’s, while its Old English origins make it a wise choice for amber & dark ales.

Attenuation: 72-85% - Flocculation: Low-Med - Alcohol Tolerance: 10% - Temp: 17-21°C
Assumed Origin: Unknown (London)

One pouch of yeast is good for:

23L of wort up to 1.048 or

20L of wort up to 1.060

Contains more than 200B yeast cells. For Lagers or high gravity ales use two pouches or make a starter.

How To:
- Refrigerate until ready to use.
- Massage pouch contents to mix into consistent slurry.
- Sanitise the outside of the pouch.
- Tear open pouch and pitch your yeast into well aerated wort at the desired temp.

Swelling of the pack is not an indication of a problem with the yeast. The yeast is still perfectly fine to use (assuming it is within date and has been stored properly). We store all of our Froth Yeast in the fridge between 2℃ - 4℃ and include an ice pack with each order to keep the yeast cold whilst in transit.

Here is a great article from Omega Yeast that explains what causes yeast pouches to swell and why it is not something to be concerned with in and of itself.

I ncludes an ice pack for shipping at no additional cost to keep your yeast cool during transit. Refrigerate as soon as you receive your order.
