General Homebrew Discussion / Magic Hat #9 Clone
« on: February 20, 2013, 01:19:13 PM »
I brewed this and just now getting to taste it....really like it. Magic Hat#9 is a vermont brewer (http://www.magichat.net/elixirs/9).  found this recipe and went with it. must say its very close and tastes great. the apricot puree gives it the same fruit taste without the sweetness, very similar to magic hat #9.

anyway, here's the recipe if interested:

You're well below the gravity where I would worry about temperature, so I say go ahead and start letting it warm up.

ok appreciate it. and would you let it warm up and let it stay there until finished, or move it back to freezer after a few days and slowly drop temp to 45F..then transfer to keg after 2 weeks for lagering at 32?
Warm it up. Fermentation will speed up and finish in 2 days in my experience. Then cool.

thanks again so much..as you can see im new to lagers...been an ale guy exclusively until recently. already learned something today..pitch below target temp..around 45F next time!  question on that - i use copper chiller and can get wort down to about 60F. should i then stick the brew kettle in my freezer and wait for it to hit 45F, or transfer to carboy with airlock into freezer and wait for it to drop to 45F? not sure if the time in the kettle even with lid would expose wort to too much oxygen, and therefore carboy with airlock would be better.

If you are going to a secondary, you can do the d-rest now, but I just leave mine in the primary for a month without D-rests.  The yeast finish the lager off without a problem.

no secondary...right to keg after fermentation is done. but considering i have diacetyl present now at 1.020 (75% of target 1.010) im questioning moving it now to d-rest or waiting for it to move a little lower just in case the beer actually finished up lower than 1.010..get what im saying?

i will have to experiment with lower pitching temps and compare.

Yeah, you should.  I found that my lagers turned out better when I started pitching a bit below fermentation temp and letting it rise to the temp intended.  Give it a try and compare the results to what you're doing now.

+1 - much, much better...

i believe you guys..probably my mistake last time also denny where i had slight diacetyl in the last lager Denny.

right now its at 1.020, and i tasted a touch of diacetyl. should i pull it now for d-rest or wait for it to move a few more points? i know my target FG is 1.010, which would make 1.020 the appropriate d-rest...but what if the beer intends to finish lower at 1.008-9. i'd hate to pull it early at 1.020 if that were the case...what would you guys do?

just wondering if waiting another day or two fermenting at 50-51F is better than pulling it now for d-rest, just in case it does end up at under 1.010.....any suggestions would be greatly appreciated!!! thanks

Quote from: BrewQwest
.....IMHO, your fermentation stage is only 61% completed from what you described so why would you want to do the D-rest this early? my math may be wrong and if so I apologize...cheers!!-
Man, I apologize... For some reason I computed your attenuation rate reached at point 1.020 which was (51-20)/51 = 60.7% instead of your completion percentage... And when plugging your starter size into yeastcalc it helps if I remember to put it in gallons instead of liters ...No wonder I had the cell count off by so much... doh!!!... Sorry again...

no worries  ;D

denny- this is the beer cleaned up diacetyl with dry yeast a few weeks ago with you awesome tip!
What dry yeast?

Most of my lagers of that OG range are done in 5 or 6 days. I pitch at about 44 to 45 F, so a wrmer pitch means it will start faster, but may make more VDKs.

Time to do the D rest at 1.020 for a 1.050 beer Is about 1.020 so I agree.

thanks for confirming the math... i guess i figured pitching at 60F was only slightly higher than my target ferm temp of 52F.  once i put it into lager chamber, it didn't take long to drop down to my set temp of 52F. hopefully this isn't a negative in the final product. i will have to experiment with lower pitching temps and compare.

maybe my math for figuring % fermentation is off...if im looking for about 75% completion, whats the formula?

thanks

Looking at Mr. Malty and Yeastcalc, you needed 375 Billion cells if that was a 5.25G batch.  If you pitched 500B, then that speed would not surprise me.  That being the case, take a taste and see whether you need a diacetyl rest at all.  You pitched plenty of yeast and sounds like they were quite healthy!

Dave


dave- thanks for the constructive feedback. my fault for not saying, but i was 5.75 gallons in the carboy.  mr.malty and other calcs called for about 410bil, so you are correct stating i pitched a little high (by design).

i was just surprised how quickly its moved. im targeting around 1.016-.017 to do the d-rest...i just prefer to do it as matter of practice vs. skipping it and getting burned by the butter...so to speak. ;D

thanks again for the feedback.

First off....pitching your gallon starter is not really what you did...you made two of the one-half gallon starters which is not the same at all... did you use a stir plate? did you aerate with an aquarium pump? did you use oxygen? forgive me if I do not know your past posts, but many people coming to this forum would not know either unless you specified with more information......IMHO, your fermentation stage is only 61% completed from what you described so why would you want to do the D-rest this early? my math may be wrong and if so I apologize...cheers!!-


right.... ;)   you can relax now.

So I pitched my 1gal starter of wlp802 ( .5 gal stepped to another .5 gal...estimated at 500 bill cells) into my pilsner at 1.051OG. I pitched decanted starter into 60f wort and It started fermenting after 6 hours, and now at about 81 hours of fermentation, it's at 1.020. I'm thinking tomorrow night I better do the d-rest, as at 1.019 I'm at about 80% complete since my final should be about 1.010.  My fermentation temp has been 51-52f.  This just seems really fast to me...but I've never used this yeast before.  Ay thoughts?

So I ran the test- thermowell vs. probe attached to outside of carboy, insulated. The Johnson control probe is in my thermowell, and does not register decimal temp...just whole numbers(52f)My probe on outside of carboy runs decimals(51.5f). so the difference seems to be about 1 to max 1.5f ,as I would have expected.
Please pm me the particulars of your test....as a 1.5 degree temp swing (especially with a johnson controller) between actual and ambient, does not seem to follow the test curves plotted by many of the home brewers....especially since you just started a fermentation less than a week ago and my posts are only a couple days old...thank you and cheers!!

My fermentation started Saturday....3 days ago .  Using a Taylor probe thermo and my Johnson controls. When both were strapped to outside of carboy, they registered no difference ( 51 and 51.5f....)As I stated, Johnson controls probe temp is whole numbers, and Taylor is decimals. I'm not sure if the Johnson controls turns off at my set temp of 51f at 51.0' or 51.9f....there lies the unknown differential between the two test probes. I watched my probe attached to outside off carboy drop to 50.5 before my freezer kicked off, and Johnson control registered 51f.  So I'm figuring about 1.5f differential between the two.  If I'm reading your post correctly, you indicated 1.5-2f difference between thermowell and insulated probe.....so I'm basically stating my results are the same at about 1.5f difference.

While it's true that ambient can be much warmer than actual wort temp, when you place your probe in contact with fermenter and insulate it, you're not measuring ambient - you're within no more than +/- 1 degree of the wort temp.

I used to think the same as your quote above, but I am one who questioned it the more I thought about it...So I performed an experiment placing three thermometers inside my fermentation chamber.  T1 was placed in a thermowell at the center of the glass carboy. T2 was taped to the outside of the glass carboy half way up its height and then insulated from the surrounding ambient air in the fermentation chamber. T3 was placed inside the chamber only to read ambient temps. Throughout the fermentation process all probes were within a degree of each other until the yeast activity began to really ramp up. At that time, T1 would follow the increase in yeast activity. T2 would lag behind a couple degrees and T3 would continue to read the ambient which was nearing 1.5 degrees lower than T2 which was 1.5-2 degrees lower than T1 which was reading the interior of the vessel. So at max yeast activity, there was a 3-3.5 degree spread between ambient and internal temps. Now if I want my yeast to ferment a lager at 52F, I want my yeast to ferment at 52F...not 55-55.5F...Ergo, the temp controller is hooked to the probe reading the internal vessel temp, not the other two... YMMV...If you have not performed this test on your own fermentations you may want to give it a try... cheers!!!

not as rigorous as your tests, but when I got my first conical, I tested the actual wort temperature versus the temp read by the probe velcro-ed to the side of the cone at various points during fermentation (i was seeing if it was worth it to get a thermowell), and even at high krausen the dead center of the wort was within a degree (as measured by my 24" SS thermocouple probe and Palmer Wahl reader) of the probe affixed to the side.  It was enough to make me forgo the thermowell - I always ferment on the lower side of the range anyway, so even if its 1df off, no biggie.

never tested ambient - figured it was irrelevant.


So I ran the test- thermowell vs. probe attached to outside of carboy, insulated. The Johnson control probe is in my thermowell, and does not register decimal temp...just whole numbers(52f)My probe on outside of carboy runs decimals(51.5f). so the difference seems to be about 1 to max 1.5f ,as I would have expected.
