I've not had this beer, but is it super flavorful or just bitter as hell? 130 IBU from the 60 minute addition is a ton IMO, but again I've not had the beer in question..

wonderbread23 09-06-2011 07:42 PM

Way too much crystal malts for this beer. It has a very lean malt profile akin to PtE.

heywatchthis 09-07-2011 12:09 AM

Agreed with the crystal. You really need to use mostly base malt with a little sugar and maybe .25 to .5 pounds crystal malt...no more. Hop schedule looks nice.

this beer is pretty epic, here's my video review of it:

theveganbrewer 07-25-2012 01:11 AM

I can't take credit for any of this except the listening and re-writing, but the brewer was on the brewing show with Jamil. Here's the recipe.

Adjust Hops additions as follows once you know what % your hops are:

@60 minutes-Nugget - 30-35IBUs
@30 minutes- Citra- 17-19 IBUs

Then add the same amount of Citra for the 15,10,5 additions. Proceed to dry hop with the values in the original recipe, do not adjust like the bittering additions.

2# is 15,10,5 Citra.

Calculated IBUs, ProMash. Whirlpool, but no addition. Flame-out, start whirlpool for 20 minutes, then knockout. Cool to 70-78. Add yeast inbetween boil kettle and yeast via a oxygen stone. California Ale, White Labs 001. Pitch at 70 degrees, hold at 67.

Unfiltered water, same as Sierra Nevada. Hard water. 6-8 days in primary. Do not raise temp. Dry hop 2 days after

ferment is complete. Pull yeast off, then dry hop. All dry hopping done warm.

They cap off the fermenter after each DH. All Pellet hops.

Sugar is not added to this beer per the head brewer at Kern River.

bobbrews 08-06-2012 12:31 PM

I knew that already. However, if you're brewing an extract or partial mash version, you'll have to make some minor tweaks to the recipe in order to get it to attenuate lower than the AG version. For extract and partial mash IIPAs, you have little to no control over mash temp., so sugar additions in the appropriate %'s can help. I included both versions above so partial mash brewers who wish to attempt have some choice in the matter.

theveganbrewer 08-06-2012 06:47 PM

My fault bob, I thought this was the AG thread. Had both on my subscribed list.
