Don’t see much difference between these two bottles, do you? The bottle on the left is the regular Jester King Wytchmaker Rye IPA (my 2011 Beer of the Year!). The bottle on the right is the Wytchmaker Farmhouse Rye IPA.
The only difference between the two is the Farmhouse Rye IPA uses farmhouse yeast in place of the regular ale yeast. This gives it a slightly sour and funky flavor. It pours a little cloudier, and the aroma is just a touch funkier, with a touch of sourness added to the flavor. The difference is subtle, but nice. I don’t think it makes it a better beer, and it is not substantially different either, but it is still damn good, 9.5/10.
BONUS REVIEW!: The Farmhouse Black Metal is an improvement over the already excellent Black Metal Stout. The sourness from the farmhouse yeasts adds another flavor dimension and rounds out the dark chocolate, dried fruit, anise and dark brown sugar flavors. Again, any differences between the two beers is subtle, but liked the farmhouse version a touch more. I gave the regular Black Metal Stout a score of 8.5, but the farmhouse version gets a 9/10.
