Saisons are sturdy farmhouse ales that were traditionally brewed in the winter, to be consumed throughout the summer months. Not so long ago it was close to being an endangered style, but over recent years there's been a massive revival; especially in the US.
This is a very complex style; many are very fruity in the aroma and flavor. Look for earthy yeast tones, mild to moderate tartness. Lots of spice and with a medium bitterness. They tend to be semi-dry with many only having touch of sweetness.
