Default First all grain taste grainy/husky. What went wrong?

The question says it all. Here is the recipe:

Ingredients Amount Item Type % or IBU

0.50 lb Rice Hulls (0.0 SRM) Adjunct 4.3 %
5.50 lb Pale Malt (2 Row) US (2.0 SRM) Grain 47.8 %
5.50 lb Wheat Malt, Ger (2.0 SRM) Grain 47.8 %
1.00 oz Hallertauer Mittelfrueh [4.20%] (60 min) Hops 15.1 IBU
1.00 tsp Yeast Nutrient (Primary 3.0 days) Misc
1 Pkgs Hefeweizen Ale (White Labs #WLP300) Yeast-Wheat

Beer Profile Estimated Original Gravity: 1.041 SG (1.044-1.052 SG)
Measured Original Gravity: 1.040 SG
Estimated Final Gravity: 1.010 SG (1.010-1.014 SG)
Measured Final Gravity: 1.004 SG
Estimated Color: 3.9 SRM (2.0-8.0 SRM) Color [Color]
Bitterness: 15.1 IBU (8.0-15.0 IBU) Alpha Acid Units: 0.8 AAU


I had a little trouble with the mash temp. It was a little high, then a little low but finally got it right and mashed at 151 for 60 minutes, then batch sparged with 3 gal at 168 to achieve my boil volume of 6.5 gal.

What could be the reasons for the grainy/husky taste?

I mash my Hefe's for 90 minutes. Your OG is a bit low for a Hefe.

Did you vorlauf your sparge?

Yeah, I was pretty disappointed with the OG. My efficiency was crap(55%), but I just chalked that up to my first AG attempt. My second attempt was about 65% so I guess I am learning.

I vorlaufed about a gallon back through the tun.

I would say 50% wheat is pretty high.

However, the crush. How did you crush and what was the dispersion of particle sizes? Crush coarser and see if it helps next time. I always add around a half pound rice hulls, so I don't think that is it.

Hmmm, now that I see the two posts before mine...

What is your mash tun hardware?

On the other hand, I think too fine a crush can kill efficiency too. This may still be the reason.

Since you are tasting it, have you brewed a second and even third batch since this one?

Do you have particles floating in the beer or is it pretty clear?

Its a hefe so its not clear. My mash tun is a 5 gal igloo w/ a ss braid. I have brewed a 2nd batch and the wort runoff looked pretty clear with no floating grain particles.

I had the grains crushed at my lhbs so I wouldn't know whether it was a course or fine grind. Is there a good way to tell what grind I am getting?

do you have a water report for the water you were using. Maybe your pH was off and you extracted an excessive amount of tannins. This could also be the reason for the poor efficiency.

Too high a sparge temperture and too much sparge water will also cause it.

My city water report says the pH is 7.9. Is that too high and if so, what should I do to lower it?

My sparge water was dead on at 168.
