Here's a wheat beer brewed with 100% wheat as based malt. Had no issues at all with my mash tun, no stuck mashing.
This is the recipe:
8# Briess white wheat malt
1# Briess Carapils
1# Briess Vienna
1# Briess Aromatic
1# Rice hulls
Mashed at 154F for 60min.
Hops were as follow:
1.65oz for 20min
2.55oz for 5min
Fermented at 67F with dry yeast S04
Irish moss was added on last 20min of boil, and here are the beer numbers:
It came out looking like a bluemoon, without the orange and coriander flavors, but very refreshing.
