"Found" Beer?

Can you call something "found" if you never knew it was lost in the first place? It was there all along, after all.

I've spent a few hours over the past couple of nights screwing around in the brew garage - listening to music, organizing small bits into storage drawers, putting away stuff that I finally got around cleaning... I even recorded a video for "Home Brew Wednesday" on YouTube (https://youtu.be/TfaZyKQWk6Y).

I'm not sure what possessed me to move some stuff at the front of the shelf where I cellar beer, but I discovered a long-lost gem at the back: one of my first Rye Pale Ales (based on the Can You Brew It Terrapin Rye). That episode aired in the middle of 2010, and I ordered the ingredients from Northern Brewer on my lunch hour at work, so that had to be in May or June of 2010.

I don't think I can adequately express in words the feelings I had when I made this discovery... Excitement? Elation? Anticipation? Amazement? Intellectually, I do know a couple of things about that discovery however... I loved that beer, and have loved it every time I have made it; and I was going to drink it. Soon.

I was already set for that evening as far as beer intake goes. Plus, I wanted to set myself up right for this tasting: clean palate, note taking materials, proper chilling, etc. So I placed it in the laundry room fridge, careful not to disturb the yeast at the bottom of the bottle.

It was remarkable how brilliant the beer appeared in the bottle: I could easily read 12 point print through the beer in the bottle! The ring of sediment at the bottom was further evidence of how time had cleared this beer. I went to bed longing to try this nearly-five-year-old beer! In fact, I dreamt about the tasting session - a surreal dream where several of us sampled the beer and discussed its merits and detractors...

The next day, there was a break in the weather, and I opted for the responsible choice and began my evening by mowing our lawn for the first time this year... That 2010 Rye Pale would have to wait. And then I had to make dinner. It was beginning to feel like I would never get to the beer!

With my tasting notebook and a purple fountain pen in hand, I finally settled in to pour my 2010 Terrapin Rye Pale clone at about 8:30 PM. I was excited and nervous at the same time! It was a great beer in its prime, but had it stood the test of time?

Appearance:
As previously mentioned, I could sense its brilliant clarity in the bottle - a careful decant preserved that. It poured a brilliant copper with a tall, white, rocky head that lasted and lasted - it simply would not dissipate. I'm sure the rye malt had something to do with that, and the fact that it had a good foam stand was a good indication that there was no contamination. The carbonation was lively, with tiny bubbles rising to the head. As I drank the beer, the head did not fade, and it left a heavy lacing on the glass.

Aroma:
Virtually no hop aroma remained - at least given the original hop schedule (over an ounce added at 10 minutes and flameout and 1.25 oz of Amarillo as a dry hop). There was a subtle spiciness in the nose - perhaps the rye, perhaps the Goldings or Fuggles hops? I picked up something else in the aroma, something elusive... I couldn't put my finger on it. The closest I could come was slightly vanilla-toffee, just a hint.

Taste:
The only hop character that remained was the overall bitterness - no definable hop character. In other words, I could no longer detect any of the distinct hop flavors: no Fugg

le, no Goldings, no Cascade, no Amarillo - no identifiable hop character. There was bitterness to balance the malt, even after 5 years. The malt had definitely moved forward as the beer aged - it used to be a hop-forward ale, with a spicy-rye malt undertone.

That ambiguous/fleeting aroma that I had a hard time naming was also present in the flavor, which is no surprise given how much smell factors into taste. I believe that aroma/flavor is oxidation-related, because I associate it most closely with bottled British ales, like those from Fuller's or Samuel Smith. It was a bit caramel-like - sort of toffee? It was not nearly as strong as in the aroma, but it was definitely there almost as a subtext... There was a bit of oxidative twang as well, but nowhere near enough to be unpleasant.

Mouthfeel:
I was pleased to find that the beer had not thinned over the half decade it cellared in the garage. I do believe that all of the hop character dropping out of the beer did affect the mouthfeel, because when it was fresh, between the rye and the hops, it had a strong medium mouthfeel, falling just short of chewy. Over time, it had now settled into the medium-light mouthfeel range, and the carbonation helped contribute to that as well.

Overall:
Wow. My excitement at the discovery of this beer was tempered with a heavy dose of apprehension: time is the enemy. Oxygen, contamination, temperature swings - any number of variables could have crushed this beer. It is nowhere near the original beer, but it held up OK. It was enjoyable. Not as zippy as the original, it did have the pleasant oxidative character I like in bottled imported British ales. The clarity, head retention, and lacing were amazing. I kind of wish I had discovered this bottle 2-3 years ago, because I can imagine a happy medium between the original beer and the 5-year beer, and in my mind's eye, that seems amazing!

"Lost" beer? "Found" beer? It is gone forever now. But the record of its tasting will live on...

Time for a Brew Kettle Modification?



SS Brewtech Trub Dam
While reading a brewing magazine recently, I saw SS Brewtech's Trub Dam. I currently have a copper tube, perforated with holes and covered with stainless steel braid; it is prone to clogging with
My current kettle screen
trub and protein break... at the very least, it slows WAAAAAY
down towards the end of the draining process.

1" copper pipe, flattened/notched 3/4" copper coupling, 90° elbow
I sketched up a similar trub dam which used copper fittings. Some cutting, simple soldering - it was possible. I decided it was at least worth a try.

Materials:
1/2" x 1/2" threaded adapter
1/2" copper pipe (1")
1/2" copper 90° elbow
3/4" copper coupling
1/2" copper tube strap





  • I soldered the copper pipe section into the threaded adapter. This gets screwed directly to the threaded valve on the kettle. 
  • I had hoped to find some copper flashing for the main portion of the dam/diverter, but I could not source any locally. I got creative and cut the 3/4" copper coupling lengthwise, then bent it open and flattened it out; I notched it about 1/2" and bent that up for a soldering surface to connect to the 90° elbow.
  • I worked the 1/2" copper tube strap into a "C" shape to match the width of the flattened coupling. I filled the screw holes with solder, then soldered that 90° to the flattened coupling as the diverter on the dam. I trimmed the base to fit

I'm hoping that I can get the wort going in a "whirlpool" as I chill it, and use this new diverter/dam fitting to keep the trub and hop mass out of my wort as I drain it into the carboy...

Brew Day: Two Dry Stouts!

With Saint Patrick's Day a couple of short weeks away, I find myself without anything appropriate on tap! I always try to have something dark and roasty on - either a stout or a porter, o
r both! I am not the type who thinks of darker beers as winter seasonals... I can drink a porter anytime, and a dry stout functions just fine as a "lawnmower beer" for me.
Sláinte Mhaith - my dry stout

I have a standby (award winning) dry stout recipe that I brew at least 2-3 times per year. It is consistent and a pleaser for any fan of the style. I call it 'Sláinte Mhaith' (SLAHN-cha wa - Irish Gaelic for 'Good Health'). It is really just the recipe from Brewing Classic Styles (http://www.amazon.com/Brewing-Classic-Styles-Winning-Recipes/dp/0937381926) by Jamil Zainasheff (@mrmalty) and John Palmer with whatever uniqueness my system/process lends:
70% Maris Otter British Pale Malt
20% Flaked Barley
10% Roasted Barley
I use WY1098 British Ale as my yeast...

I have always loved stout - I was among the first people I knew to like Guinness (I will not admit how early). Like many brewers, I originally fell prey to the "more is better" thinking when formulating my stout recipes. When I sat down to write this blog entry, I looked back through my recipe binders and brew logs... There were TEN stout recipes (American and dry). Each was decent - I don't believe I ever made a terrible stout (I have made a few terrible beers though). But none of them was what I was looking for - thus the ten different recipes, none brewed a second time.

Then I listened to Jamil's Dry Stout  episode on The Jamil Show (http://thebrewingnetwork.com/shows/The-Jamil-Show) - the original one, not the Brewing with Style newer one... He talked about the simplicity of classic Dry Irish Stout. I brewed that recipe, which he later included in the book referenced above: it was exactly what I had been pursuing! I have been brewing that exclusively as my dry stout recipe ever since.

2015. The year is young, and I have been immersing myself in brewing media: Basic Brewing Radio/Video, the beer engineChop & Brew, Brewing Network... Was it time to brew a different stout? Should I put more than one stout on tap? An episode of Chop & Brew and an entry in the beer engine blog featured a Beamish-inspired dry stout - I had tried clones of Beamish in the past, but they had fallen short. This recipe, and the subsequent tasting on Chop & Brew, seemed compelling.

I talked through my ideas with my local brewery's tasting room manager (and former student), and he mentioned he had a nitro system that was not currently in use. What?! He offered it to me on loan! That iced it - I was going to brew both, and serve them both on nitrogen!

Brewed and ready for March 17th. No green beer here - only proper stout!
