dirt flavor

[wacko]

I'm having a weird flavor in my beers recently. Best I can describe it as "dirty"

I do biab method and I have been asking my lhbs to double or triple mill my grains and I'm wondering if that flavor could be coming from the grain husks getting over crushed?

 

[nealf]

What hops did you use? What was your grainbill?

 

[devilishprune]

Have you changed anything else on your brewing lately? Since you said it was for a few beers, is there any ingredient that you used consistently between them?

 

[wacko]

No, nothing the same. Different hops and different grains for 2 batches.

Do you have a picture of your husks you could post?

Typically shredded husks result in a tannin flavor. Which to me tastes like an over cooked black tea bag.

I make wine as well, so I know tanin flavor. Its not that.

We needs a recipe.

I did this one:

Recipe Type: All Grain
Yeast: dry, neutral
Yeast Starter: recommended
Batch Size (Gallons): 5.5
Original Gravity: 1.084
Final Gravity: 1.020
IBU: 81.4
Boiling Time (Minutes): 90
Color: 15.9
Primary Fermentation (# of Days & Temp): 7 days at 65º
Secondary Fermentation (# of Days & Temp): 14 days at 65º

I found this recipe on the internet somewhere, and I've made it in the past. If it's not spot on to the original, then it's pretty frickin close. I use pacman yeast to ferment this, but any dry or neutral yeast will work fine.

I think I might have it figured out. I'm wondering if I didn't clean my mesh bag well enough on those batches.
