Hi
I have made a couple of batches of wheat beer recently with equal amounts of pale and wheat malt and noticed a fall off in mash efficiency (80% down to 68%). Temp and PH of most recent mash were ok.
I am starting to wonder if this is a function of the lower conversion power of the wheat malt. any thoughts?

Yes potential yeild is higher I think which makes all the more puzzling, but I suppose I was thinking 
about the diastatic power of wheat malt which I think is low and the mash will rely more on enzymes from the pale malt.
with everything else being equal compared to mashes with 80 to 90% pale malt perhaps the best thing to try are longer mash times (normally do 60 minute mashes) and see if that gives an improvement if only to satisfy my curiosity for in practise I will just increase the grain bill by 0.5 a kilo
