Beer Recipes / Re: issue with Summertime Ginger Ale for Big Brew 2016

There is 0.5 lb of lactose, which should not ferment, so it seems that the final gravity should be above 1.000.

Any differences are likely to be quite subtle and not necessarily better so go for the 2 row.

Thanks. I'm going with mp3 because my stock software doesn't do AAC and because I've converted a lot of my vinyl to mp3.

All Grain Brewing / Re: How do I start all grain brewing
« on: June 07, 2016, 02:55:32 PM »
There is a bit of a learning curve to this.  Join your local homebrew club to shorten the learning curve the most.  Someone there will surely invite you to brew with them so you can get a hands on experience and give you some tips.

All Grain Brewing / Re: How to add coffee to a stout
« on: June 04, 2016, 02:45:27 PM »
I find that the coffee flavor fades and when it does it tastes off so I like to add the coffee beans to the keg and leave it in there until the keg kicks.  On the other hand, I would not keg a RIS.  I think Hoosier's recommendations are good; you get a beer that has coffee flavor rather than carbonated coffee.

Thick Ass Stout by Skankin' Pickle is my official theme song.

Nice! https://www.youtube.com/watch?v=t7CpTC9fm68

The Pub / Best beer themed songs
« on: June 03, 2016, 02:28:22 PM »
I searched for a thread on this and was surprised to not find one here.  My current no.1 is Too Drunk to Fu*k but I suspect that is only because I haven't see your no. 1.  What is your favorite beer-themed song?

The Pub / Best digital format

I've begun converting all my CDs to play in the car.  Which format is better, mp3, wma or aac?

Fidel tell us how you've set up the thermocouple.

Yeast and Fermentation / Re: Doh! Yeast starter blunder.
« on: June 02, 2016, 04:02:54 PM »
My guess is that the hefeweizen yeast will not be active at lager temperatures and thus have negligible impact on your current lager and your future lagers.  I don't have enough experience with hefeweizen yeasts to make a more educated guess.

Equipment and Software / Re: Chest Freezer/Temperature Control
« on: June 02, 2016, 02:35:29 PM »
My point is about the temperature of the freezer when the fermentation temp controller turns the freezer off.  Do you want the freezer to be 40*F, 20*F, 0*F, etc?  If it is 0 *F, the fermenter temp will drop significantly below the desired temp.  The OP says it drops 3 *F below his setpoint.   Of course the temp undershoot also depends on the mass of the freezer versus the mass of the beer.

General Homebrew Discussion / Re: rolling boil?
« on: June 02, 2016, 02:26:23 PM »
What is the deal with "thermal stress?"  The last time I checked boiling wort was a liquid without feelings and without a metabolism.

I thought that lowering the boil rate in commercial brewing systems was driven by energy savings, which conceivably can be very substantial for a big operation.  Could be entirely wrong on this point.

I suppose that the temperature of boils can be "considerably" higher than 100 *C if the kettle is deep enough, which is not a concern for homebrewers.  For grins, I looked at a steam table.  The boiling point of water/water at the bottom of 15-16 ft of water/wort is 232 *F, which could be a concern for commercial brewers.

5.  Warmest, assuming that the freezer temp setting is cooler than the desired ferment temp.  Having it on warmest reduces the temperature overshoot (3 F in your experience) because the freezer is much colder than the desired fermenter temp.
Really? My understanding is that the compressor is either on or off and that the freezer's built-in thermostat simply changes the set-point. Since even the warmest setting would ostensibly be "below" 32F this shouldn't matter. That said, since we're already using the temp controller to cycle the power on and off it seems that setting the freezer to "coldest" would be the safest, since it minimizes the chance for the freezer thermostat ever doing anything. Am I missing something?
If the thermostat cuts a freezer off at say at 32 F, then the freezer is still cooling the fermenter.  Stable temps are better than fluctuating fermentation temps.

Think you're partially wrong here. The dial on the freezer is a thermostat, basically a switch that cuts off at a given temp. It is functioning the same as the external controller, but at a lower range. That said, warm on the chest freezer might be warmer than 32 which is where I crash. I set both my keezer and ferm feeezer to the cold side of the dial.

The OP said the following: "3:  I have the freezer set up, but empty.  The controller is set at 63F and the controller shuts the compressor off at the set temp.  The freezer, however continues to chill to below 60F even after it is shut off."

To reduce the overshoot of the cooling, the freezer thermostat should be set to a warmer temperature that is still below the desired temperature, say 10 *F below.  If the freezer thermostat cuts off the freezer at 10 *F below the ferment temp, it will still be cooling the fermenter.  Eventually, as the freezer warms up it will turn back on unless the ferment temp has hit its target in the meantime.

I wonder if homebrewers who did not like black patent were not properly adjusting the mash pH.  The pH readings suggest that black patent is more acidic than the other dark malts even at the same nominal lovibond value.

Would it make a difference if the black patent were to be added to the mash just before vorlauf?
Greg Noonan, RIP, suggested doing just that, but the flavor impact from dark grains added after the mash is a lot less than added at the start of the mash.
