SPAb3 + bringing yeast back from the frosty grave
Now, I probably looked at the starter every 15 minutes for the next 5 hours, until I went to bed that night. Took a big sniff before I went to bed to see if I could sense any hint of fermentation going on.

Leon: brewed
- Added 5 vials of Wyeast 1056 to the frozen yeast bank
- Dry hopped and racked the 2nd batch of Stonington Pale Ale to secondary. This pale ale smells fantastic already...I can't wait to see what additional layer of hoppiness the dry hopping will impart on the beer. And 1056 is a terrible flocculator. I really wish I could cold crash this beer. I'll hit it with gelatin at the end of the dry hopping to give it some chance at clarity.
- Brewed up a big DIPA (who's moniker is also Leon). We didn't have the Simcoe, so replaced those additions with more Centennial. No worries, as there's always a next time, and it'll be interesting to see about changing this one element to the DIPA in a future batch of Leon. Jason and I intend this beer to play back up role to the late fall/early winter encore of what will surely be a stellar showing for Leon (the beer's namesake):
I also had to take the good with the bad, as my prized 50L Pyrex reactor cum fermentor shattered in to many life threatening shards of glass. Thankfully, its loss was the worst of it, as I only suffered a small cut on my left hand and many gallons of sanitizer (not beer) dumped on to the kitchen floor. Enormous jugular hungry shards of non-safety glass lay before me in a soapy mess that made Jason ask nervously 'are you alright, buddy?'

Frozen Yeast Banking
- some plastic screw top tubes (a fellow Boston wort, thanks Byron, donated some 50ml sterile centrifuge tubes to my cause). Otherwise, you can find them in bulk (100 tubes/pack) for about a buck a tube, or in smaller quantities on ebay. You could certainly use smaller tubes, and if you don't get the sterile tubes, you can sanitize them before you put your yeast/glycerine solution in to them. If you choose to boil sanitize, make sure the tops can be boiled, some are made from a lower temp compliant HDPE than the tubes themselves. Screw tops are important to ensure a good seal.
- 100% glycerin. This is the key to freezing yeast. It acts as a cryoprotectant, which means that it helps to prevent large ice crystals from puncturing the yeast cell walls. That's what would otherwise kill your slumbering yeast cells. With some internet shopping, and some trips to 3 local (massachusetts) pharmacies and the health food supplement section at whole foods, the best option I found was a double-16oz.bottle pack at amazon.com for ~16bucks, free shipping, no tax. tough to beat amazon, for price and convinience, once again. I understand that once opened, the glycerine doesn't 'go bad' either, so no worries about getting such a large quantity. If the link goes down, just search amazon for Now Foods Vegetable Glycerine. Found some glycerine at whole foods, but it was 10 bucks for 4ozs. uh... yeah.
- Turkey baster
- Santizer
- Freezer
- Save yeast slurry from a starter or from a primary, and wash the yeast, if desired. I didn't wash, which isn't ideal, but sometimes extra steps are just another chance to introduce contamination. At least that's what I tell myself sometimes. Store the slurry in the fridge. I can't quickly find the reference, but storing the yeast in chilling temps causes the yeast to build up trehalose in the cell wall, further increasing its ability to survive the freezing/thawing cycle.
- Make a 50/50 solution of glycerine with water (glycerine is soluble in water), and microwave to boil to sanitize for a few minutes, cover with plastic wrap and cool in the fridge.
- In order to make 15% glycerine solution, I'd need 7.5ml of glycerine in my 50ml tube (50 x .15 = 7.5), if I fill them. I don't plan to completely fill them, in order to leave some headspace to allow for expansion when freezing, but I'll still shoot for 15ml of the sanitized cryoprotectant solution. I made 1/4 cup + 1/4 cup, way more than what I needed for this small batch of tubes. Those 16oz bottles will last me a while, which is great.
- Insert your santized turkey baster in to your yeast slurry, holding down on the bulb, then when you hit the top of the slurry, try to suck up the top most part (highest yeast cell concentration, if you didn't wash).
- Store the mixed yeast slurry/glycerine in the fridge for a couple days, before freezing. Rationale here.
- Ideally, you'd then store in a chest freezer vs. a regular home freezer to prevent damaging multiple freeze/thaw cycles, but I don't have one. I've read anecdotally that other homebrewers store their frozen yeast in the 'coldest' part of their freezer with very acceptable results, so I feel pretty good about trying this.

an Indian Brown Ale plus lots of firsts
About 1/2 of this batch was put in to 12oz bottles, and is currently conditioning at the office. Final destination is the group of guys who kindly donated the reactors to my homebrew cause. I put the rest in larger flip tops, as I expect to drink this one in its peak condition, which would be within 2months.
Finished at ~6.5%abv.
____________________________________________________________
Back from Phoenix yesterday (26April), and racked the IBA to secondary on to an ounce each of Cascade and Centennial. The fermentation vessels don't have an airtight seal on the screw caps, so I wasn't able to dry hop in the primary as I intended. No worries there, but I'll probably put a bead of silicone on the inside of the caps to get that good seal for future brews. While stuffing the whole hops in to the 5 gallon carboy neck, I was reminded why the wide top opening in the reactors would expedite the process vs. a regular carboy neck. Keeping the carboy in a water bath in the spare bathroom tub, as springtime temps expectedly jumped up to the 80s over the weekend.
The primary ferment was done before this happened, so I'm hoping no off flavors from a warmer than optimal fermentation. holding in the mid to high 60s in the water bath now.
______________________________________
Brewed up this Indian Brown Ale tonight as a thanks for the fermentation vessels. here's a nice shot of the beautiful foamy wort after squeezing out the hop matter post wort cooling.
I had 6lbs of northwestern amber LME that I received as a gift from my sister Chelynn, so this recipe is a partial mash. The taste of this LME was phenomenal...rich, fresh, smooth. Almost like a soft and sweet molasses with no 'iron bite' that can sometimes be associated with it.
Anyhow, I chose a hoppy american brown ale, as I figured the guys will appreciate a decidedly hoppy brown. Oh, and plus I've really been wanting to make one. The roasty chocolate malt combined with a touch of caramelized sugars from the crystal30, and some soft belgian biscuit malt will play a backup role to the bitterness provided by the zeus and american aroma and dry hop thoroughbreds: Cascade and Centennial. If Centennial is good enough for Bigfoot and Ruination, its plenty good for my little 5 gallon batch of IBA.
I added alot of new variables to my brew day:
- Tore in to my 25kg Canada Malting ltd pale ale malt. This is base grain that I'll be using for the to-be-determined 3rd wedding beer, so it'll be good to get a sneak peak.
- Of course all of this grain is uncrushed, so I unleased my barley crusher for the first time... here's a snippet of the titillating video!
It tore through the 5.5 lbs of grain to reveal a wonderfully fresh and aromatic crush. From the mill and in to mash in minutes...I can already tell this is going to improve my beer.
- I used 1 teaspoon of 5.2pH stabilizer in my mini mash...I'll have to wait to get a taste of the brew to see if it made much of an impact. I added 1oz of burton water salts to my nearly naked boston sparge water, so I'm not too sure if this was the best time to introduce the 5.2pH stabilizer variable (to discern effect), but I figured it couldn't hurt and would probably help.
- I finally cracked in to my freshops stash. wow. the 16.4AA% zeus is almost sticky. what fun. I suspect freshops will become my sole retail hops provider to supplement my (eventual) 6 variety hops field (more on that in a future post).
- And of course, the inaugural fermentation in my 25L reactor. The larger central opening is going to really help when it comes time to add the dry hop addition. It could also be useful for top cropping, should I ever want to do that.

O Rings, Corny Kegs and you
McMaster Carr is the most inexpensive source of bulk replacement o-rings for your corny kegs...homebrew shops (most) will set a set of these to you for $5-7, so it probably makes sense just to get them in bulk.(1) Dip Tube O-Rings5/16" ID x 1/2"OD x 3/32" width
9452K172 BunaN #109
Pkg 100/$1.89
(2) Post O-Rings7/16" ID x 5/8" OD x 3/32" width

Pkg 100/$2.15
(3) Lid O-Rings3 1/2" ID x 4" OD x 1/4" width
9452K218 BunaN #417
Pkg 10/$12.31
total cost, shipped was 33.66, with $5.00 shipping.
or, here's a cheap source for O ring sets ($2.50) and poppet valves, and, well... pretty much anything corny keg related:

Wort Chiller
takes about 10-25 minutes to chill work to pitching temps, depending on the time of year. I place the chiller in the kettle at flame out to sanitize, if not doing a flame out hop addition. If doing a flame out hop addition, then I'll add with 5 minutes left in the boil. I wish there was a way for me to use the hot/warm water that is dumped out the other end of the chiller, but I don't have a garden to water (well, not one that's close enough for this to be feasible), I don't have a washing machine to load up. Something I'll do when I get out of the condo.
