Kegging and Bottling / Re: Kegging with less oxygen
« on: February 26, 2016, 12:26:01 PM »
Some of us install spigots on our buckets and gravity drain into a purged keg. Less fiddly that way.

Yes, spigots are a good direction. I have a step bit and I'm not afraid to use it! For the rest, I'm contemplating the conversation between "gravity drain less fiddly" (done last time, on a stout, with good results) versus "hoppy beers better if limited access to CO2." For the latter model, the part that feels like a hassle, honestly, is the bucket that has no spigot on it. I prefer to clip the autosiphon to the bucket, but that gets back to that wide surface of beer exposed to air, assuming CO2 will drift away pretty quickly. I was even thinking, gee, what if I have saran wrap or waxed paper ready and drop some on the wort as soon as I pop open that bucket lid.

The rest of it doesn't sound that complex. It's just parts connected to parts. I could also go super-fiddly this time, and gravity feed next time.

General Homebrew Discussion / Re: yeast starter from dry yeast
« on: February 26, 2016, 06:32:43 AM »
I'm a primary user of dry yeast but they have to be handled properly. Or at least the Lallemand does. I expect they all have similar rehydrating and pitching characteristics.

Benefit is an "instant-starter" so making a starter out of dry yeast is redundant. However, mishandling causes problems enough to make you wish you'd made a starter. Reading the product sheet reveals essential tidbits like attemperating the yeast pitch to wort temp in 10* increments or risk yeast mutations in the case of Munich yeast.

Euge, thanks to you, I have learned the word "aliquot." In practice, it sounds as if attemperation would only need one interval (if the yeast is ca. 75f after 20 minutes, and your wort is even as low as 50f, and intervals are 50f, then it seems one dollop of wort for 10 minutes would do the trick??).

Kegging and Bottling / Kegging with less oxygen
« on: February 25, 2016, 11:03:56 PM »
I ferment 3-gallon batches in 5-gallon food-grade buckets. The more I focus on oxygen, the more I realize that my practice of keeping the fermenter closed until bottling time, unless I have to dry-hop or add ingredients, has contributed to better beer. I am also evaluating whether to keep using buckets, at least this size. But for now, since I have beer to keg in 9 days...

How's this look for a oxygen-limited kegging from a bucket to a keg?

* Attach an MFL swivel flare adapter to the end of a piece of siphon tubing
* Sew dry-hopping hops into large muslin square
* Drop hops into sanitized keg
* Close up keg
* Purge keg with CO2 -- push CO2 in, release PRV -- x 3
* Insert tubing into autosiphon
* Insert autosiphon into siphon-sized hole in bucket lid
* Start siphon into 2-cup pyrex, stop at 2/3 cup mark (to fill tubing and get enough for a reading)
* Attach ball lock disconnect to beer-out post
* Attach swivel nut to ball lock disconnect
* Open PRV
* Fill keg
* Purge headspace
* Set pressure and go away for a few days

I agree that temp is number one, but a close second is pH, so if you can monitor pH, and adjust as necessary, your beers will improve greatly.

Over the last three or four years I have used a fridge, I have noticed a big increase for most beers through temp control. Even if I've been fuzzy about the narrow range, keeping temps within the mid-60s is a big improvement over letting them swing way up and down, and my favorite Common went way up in quality once I was able to drop and hold it to mid-50s after the first 7-10 days, per the recipe. It sounds as if water adjustments and mash pH are logical next steps, particularly given that water sources in California can vary so much due to the drought. Just not quite there yet... more gear, more consumables, etc. Not so much a cost issue as just... more to learn, think about, do. Using filtered or spring water with a pinch of Campden has been my go-to, and anything else is... more.

General Homebrew Discussion / Re: Suggest an experiment!
« on: February 23, 2016, 10:38:24 AM »
Could also have been suggested, but in re-reading the various keg purging threads, another experiment could be splitting a ten-gallon batch of hoppy beer three ways and then racking to a non-purged keg, an unpressurized keg purged with N CO2, and a pressurized, purged keg. (You would need to define "purged" pretty clearly.) This experiment would benefit from replication using the same recipe and kegs of the same size.

Or you could do this instead as qualitative research and ask the kegs how they feel about being purged, and to share their purging experiences, then interview the beer as well. "Go on, share more." "That's interesting. Can you tell me more about that?"

Ok, thanks. I should listen to the podcast! (Which podcast?)

Thanks, Denny had noted "we discussed this on the last episode of the podcast" so I have been able to subscribe to the podcast and figure out which episode. The only downside of having a short commute these days is it has seriously cramped my podcast-listening time!

Thanks so much! I'll add to my queue. Also was able to swing by an LHBS today and pick up two thermometers for the fermenters I'm using these days.

As turbulent as fermentation is, I'd assume things are within a degree or two of uniform.

For temp controlled fermentations, I know myself and others usually just tape the controller's temp probe to the vessel and cover it in some sort of insulation. If measuring the temperature through the wall of the fermentation vessel wasn't close enough, I think we'd know it.

That's easy enough -- thanks.

Kegging and Bottling / Growing the kegging empire
« on: February 20, 2016, 07:48:19 PM »
I was very conservative on my first kegging venture, but instantly "got it." This may be because I had beginner's luck and everything has gone very smoothly, but I am feeling very post-bottle these days.

Because I was conservative, I bought one (3-gallon) keg, a 5-lb CO2 canister, and a Taprite single-body regulator (plus pre-assembled gas and beer lines). I brew small batches so the keg size is perrrrrfect. Sold on kegging, I have already bought another 3-gallon keg from AIH during their Presidents' Day sale and am contemplating taking advantage of the Williams keg sale this weekend on kegs to get one more.

So about regulators. My expectation for the next year or so is I'll have up to two 3-gallon kegs on CO2 at any one time, though with the fridge I have for my kegs (a hand-me-down from my landlord), I could fit three or possibly more. I expect to get busy next weekend and every weekend through the remainder of 2016 with my grad studies, so I am assuming I will brew more than 2015 (three batches) but less than 2014 (not sure, 6-10?). Life could change that, but it's a plan for now, anyway.

I brew different styles; right now I have an oatmeal stout on tap as my first kegged beer, and today brewed a rye IPA (*waves at Denny*), plus have a Belgian tripel in bottles. Should I try using a splitter? Get a dual-body regulator? Get another regulator and canister? What do people do?

Get one of those stick-on liquid crystal type thermometers, they're a great way to measure fermentation temps accurately.

And FWIW, I've had good results fermenting at ambient temps-but note that I typically brew British styles that benefit from fermenting a little warmer than American styles. Also, the beers this has worked with never got warmer than 66oF, as measured by a thermometer as described above.

I have used those stick-on thermometers on previous carboys, but always wondered if they were measuring the wort temp all that well. I suppose better than just guessing, but particularly with buckets, are they getting at the thermal heat created deep in the burbling depths of fermenting wort?

43
One of those questions I have hesitated to ask ("I should know this by now") is whether I should set the  the temp of the fridge a few degrees lower. In other words, if a recipe says "ferment at 68 degrees F," is that the wort, or the ambient temperature?

It's wort temp that matters.

If you don't have a thermometer in the wort, is there a rule-of-thumb offset?

Kegging and Bottling / Re: best fridge for kegging system
« on: February 19, 2016, 11:09:25 AM »
It sounds like you are looking for a mini-fridge.  I made a two tap kegerator out of this Danby from Walmart  http://www.walmart.com/ip/Danby-Designer-4.4-cu.ft.-All-Refrigerator/40487632.  Currently $193 with free shipping.  You have to modify the door to get two ball-lock corny kegs to fit, but it works great.

I bought the same fridge (though I haven't converted the door -- I have the newer model where the door is glued in, and for various reasons I just never had a need to embark on this project). If you're a CostCo member, I see them in stock quite a bit in-store and they're about $50 less than WalMart.
