Liquid Yeast YF‑116 St Hedwig 100 mL

YF‑116 St Hedwig is a traditional Polish liquid yeast designed for Grodziskie and smoked ales. This hybrid strain preserves the woody and grainy character of smoked wheat malt at lower temperatures while producing delicate pear esters as fermentation rises. It offers a subtle balance between historical authenticity and modern finesse, allowing brewers to create light, dry, and elegant beers. Recommended by Dr. Márton Pelles (Sördoktor), it embodies the nobility of the Polish Grodziskie style.
