Originating from Norway, YF-503 is a farmhouse ale yeast that tolerates high temperatures up to 40°C without producing harsh esters or off-flavors. It develops bright citrus and orange peel notes that evolve into gentle peach tones as temperature increases. This strain is forgiving and easy to work with for brewers lacking precise temperature control, delivering a clean, aromatic beer. Its consistent performance highlights subtle malt character while emphasizing hop and spice nuances.
