I'm not sure I get northern brewer, but to me this years recipe doesn't seem the same....

Brewed on 11/6. Big 4L starter on the stir plate. Pitched 48 hours after brewing, with 5+ min of air pump. Hit again 12 hours into fermentation. Transferred to secondary and dry hopped for a week with 6 oz Simcoe on 11/19. Cold crashed until 12/15 at 30-32F. Primed 4.4 gal with 2.6 oz sucrose - target 2 vols.

I dry-hopped with a crapload of Simcoe and it's super, super sweet-smelling and floral. I'd like to have it finish a bit lower, maybe 1.009. Not quite balanced enough on the back of the palate to pass for Hopslam.

6 weeks later, this was spot on. I had the opportunity to have a Hopslam on draft in Michigan, then go back home and try mine. Super close.

How is the alcohol burn? That's what always amazes me about these high abv beer is how soon they're ready. looks like you've got it down.

So what helps make a beer ready earlier? Is it your air infusion? Cold crashing?

Why did you wait 48 hours to pitch?

Nice work, sounds delicious!

Psychonaut · 02-22-2012, 02:28 PM

Thanks. No alcohol burn - you wouldn't guess it's almost 9%. Pitching a lot of a neutral yeast and fermenting fairly cold (64F) helps keep the profile clean. I think I waited 48 hours to pitch because I couldn't get the wort cold enough with my immersion chiller, so I put it in a chest freezer to take it to pitching temp.

Part of what helps make a big IPA ready earlier than other big beers is the absence of a lot of the compounds that would need aging in a complex beer, such as a RIS or a barleywine. For example, both of those do well with some light oxidization and hop degradation to eliminate harsh notes. Other beers may need time to allow tannins from dark grains to mellow out. IPAs tend to have a lot of straightforward malt, and all of the fresh hop characteristics are in style.

Psychonaut · 02-22-2012, 02:39 PM

Oh yeah, the air. Good aeration or oxygenation helps keep the yeast happy. Early in the fermentation process, yeast consume oxygen to reproduce. Next they consume oxygen and sugar to grow. When oxygen runs out, they start fermenting. Pitching a lot of yeast ensures that the lag phase (reproduction) is short and that not a lot of oxygen is consumed there, making it available for the growth phase. Hitting it again at 12 hours, before actual fermentation starts, is a way to ensure the yeast have enough. Pure oxygen would be better, but I haven't found a store near me that will refill a tank.

If you do it right, you end up with a lot of yeast and a lot of oxygen, so they get super strong and your fermentation finishes with no problems. That's important for big beers where the yeast is going to have a lot of work to do to hit your final gravity.

I have decided to clone this recipe.

so if you're cloning a hopslam clone recipe that means your doing a hopslam clone clone. Cool.

Second, I'm going to harvest some yeast from a bottle of Bells's Brown Best and make some slants. (And probably make a big-ass starter and brink it.)

Then I'm going to make about ten 600ml grain-bills, strike at 155ish, do a 90 minute boil, chill to 65 and mini-ferment them all inside of erlenmeyer flasks.

Then I'm going to bottle each one and drink them in a few weeks, with a comparative bottle.

Finally, I will take notes and adjust one variable in nine of the mini recipes and maintain a control of the "best one".

I hope I get to repeat this a few times; I like beer.
