Re-read his post. He mentions the final gravities were the same. I'm confident in US05 for big beers. In fact, I find that US05 usually attenuates a little more than WLP001. I find it's also a little less flocculate than 001, so that pretty much explains why. US05 takes my 8.5% DIPA down to 1.008-1.009 every time. This beer has more dextrose, and a lower mash temp, so we'll see.

I think i'm going to roll with 2 packs of US05 (properly re-hydrated, of course). I might get a little crazy and pitch 2.5 packs.

I was talking about the 1.089 Younger the OP is brewing... not 1.070 Elder that JonW brewed.

I feel WLP001 will lend different results than US-05 for that particular beer.

That's fair, to each his own.

35ml of hopshot!

am i wrong or does this chart suggest 7.7 ML, not 7 total viles:

Im all sort of wrong here I think

You are right if the PDF is right.

Each vial only contains 5ml.

If their chart is accurate @ OG 1.050 and 5 Gallons, (5ml hopshot = 10 IBU) and (15ml = 30 IBU), then 15ml of hopshot is equal to about 1oz of 10%AA hops, give or take a few IBUs here or there.

I would normally put at least 3 oz of 10 AA% hops into any DIPA. 15ml x 3 =45ml so the 40ml listed in he recipe doesnt seem completely out of whack, based on that math.

EDIT:

Wait that chart is per ml like you said. so 1ml= 10 IBU in 5 gallons?

that means 3ml equals 1 oz of 10AA% hops. If that is right, 40ml is equivolent to 13.3 oz of 10% AA hops!!!

Weird I wonder which is right.

mewithstewpid · 05-30-2012, 09:20 PM

yes the charts is indicating volume in milliliters, not volume in total number of hopshots

mewithstewpid · 05-30-2012, 09:24 PM

the chart also says 90 min boil decreases the need for hopshot by 10%, so, for 1.090 wort boiled for 90 min to 100IBUs you will need 10mL of hop extract, or 2 hopshots.

I took the chart and threw it in the trash. It's useless without knowing which formula they are using. I went to the Hop Union website, and found out the following.

Their generic CO2 hop extract (what I'm 95% sure hopshots are) weighs 1g per ml. Therefore 5ml weighs ~ 5g. The extract is ~ 50-60% AA. So 5ml of extract contain 2.5-3.0g of actual Alpha Acids; I'll split the difference and say 2.75g.

Now let's convert that to hops. 28g = 1oz. 28g of say....Amarillo @ 10% AA would have 2.8g AA. So that's why I say a 5ml syringe of hopshot equates to 1oz of a 10% AA hop. This takes the IBU formulas out of the equation. The extract efficiency between extract and pellets is surprisingly about the same, so that doesn't factor in.

Yes, this is a ton of IBUs depending on the calculator you use. I get 203IBU with the Tinseth formula (what I use) or 340IBU from the Rager formula. Keep in mind the popular PTE recipe calcs at 168/253 IBUS (tinseth/rager).

The PTE recipe calls for 48.5 AAU of bittering hops at 90 minutes (3.5oz CTZ @13.9%). I went with around 68AAU of bittering at 90 minutes. It's a pinch less than the 50% increase in hops the recipe uses everywhere else.

mewithstewpid · 05-30-2012, 09:31 PM

so i see what you did. if you are doing something similar to themadfermentationists recipe, its bittered to (gasp) 300IBU's.

so, 30mL of hop extract needed for 90 minutes. (already excluding the 10% for extended boil, 33mL w/o 10% decrease)

crazy. good luck

Ya, if you use the Rager formula, it's like a 340IBU beer. I think that'll be about right.
