Kveik Yeastery K.14 Eitrheim Kveik Yeast

Ferment fast, clean, and fruit-forward with Kveik Yeastery K.14 Eitrheim Kveik Yeast, a Norwegian strain known for producing vibrant apricot and peach esters with subtle orange and pineapple notes. It delivers expressive, juicy flavor even at high temperatures, making it ideal for hazy ales, hop-forward IPAs, and farmhouse styles that benefit from soft fruit character and rapid turnaround.

K.14 Eitrheim ferments reliably within a broad temperature range of 59–100°F and completes most fermentations in just 3 to 4 days when pitched at 88–95°F. Despite the warm fermentation profile, the yeast maintains a clean, controlled finish without producing harsh off-flavors, allowing hop aroma and fruit esters to shine.

Each 7-gram packet is calibrated for a standard 5-gallon batch and can be pitched directly into wort without hydration or a starter. Its high heat tolerance and efficient fermentation performance make it suitable for brewers without strict temperature control, as well as those looking to accelerate production timelines.

For best results, ferment warm to enhance apricot and peach character, or ferment cooler within the strain’s range for a cleaner, more restrained ester profile. This versatility allows K.14 Eitrheim to support a wide variety of modern ale styles, from NEIPAs and pale ales to farmhouse ales and experimental fruit beers.

With rapid fermentation speed, broad temperature flexibility, and expressive fruit esters, K.14 Eitrheim offers dependable performance for homebrewers seeking bold, aromatic beers with minimal equipment requirements.
