Old Speckled Hen Clone

Time for another new recipe. One of my favorite English beers readily available in the USA is Old Speckled Hen, an ale that falls somewhere in the English Pale Ale / Extra Special Bitter style. A quick internet search turned up this recipe at BIABrewer.info (also available on the BeerSmith recipe cloud). BIABrewer user hashie posted the recipe, so it has their name at the helm. The original recipe was developed for the brew-in-a-bag technique, so I had to modify the grain bill slightly for my own batch sparge setup.

Hashie's Old Speckled Hen
  • 8.25 lbs. Maris Otter pale malt
  • 1 lb. 120° crystal malt
  • 0.90 oz. U.S. Northern Brewer hops pellets (9.9% alpha, 4.6% beta), 60 minute boil
  • 0.50 oz. U.K. Goldings (4.8% alpha), 15 minute boil
  • 0.5 oz. U.K. Goldings (4.8% alpha), 5 minute boil
  • 0.75 lb. Lyle's golden syrup, 5 minute boil
  • 1 tsp. Irish moss, 10 minute boil
  • 1 pkg. Nottingham yeast (Danstar)
Procedure
  • I mashed in with 3 gallons of water at 164°, hitting 151.4° for the mash start. The mash temperature was at 148.5° after 35 minutes and 146° after 60 minutes. 
  • I added 1.3 gallons of water at 180°, which raised the mash bed to 151°. I let this sit for 10 minutes, vorlaufed, and collected 2.75 gallons of wort.
  • Next, I added 3.25 gallons of water at 185°, which raised the mash bed temperature to 168°. I let this sit for 10 minutes, vorlaufed, and collected the rest of the wort.
  • In total, I collected 6.2 gallons of wort with a gravity of 1.043. This works out to ~69% efficiency. It's a little less than my best brews (~75%), so I wonder if that's because I didn't use 5.2 pH stabilizer on this batch.
  • I brought the wort to a boil and added the Northern Brewer hops.
  • After 45 minutes, I added the first dose of Goldings. After 50 minutes, I added the Irish moss. After 55 minutes, I added the second dose of Goldings and the golden syrup. The syrup has a really nice toffee note to it--I am interested to see how that will translate into the overall beer.
  • After 60 minutes, I turned off the flame and chilled the wort down to ~78°.
  • I transferred ~4.9 gallons of wort into the fermenter, with a starting gravity of 1.055.
  • After pitching the yeast, I sealed everything up and put it in the fermentation chamber. Temperature is set for 66°.

Summer Blonde Ale 1.1 Kegged

Tonight I kegged the Summer Blonde Ale that I brewed up on May 10. It has been in the primary for 12 days, with a very vigorous fermentation. Starting gravity was 1.047, with a final gravity of 1.009. This calculates out as 5.0% abv, nearly identical in stats to the first iteration of the recipe. The flavor is clean and lightly malty, at least in its uncarbonated state. Approximately 4.75 gallons of beer went into the keg. I'll be force carbonating this, with an aim to have it on tap within a few days.

Beer Tasting: Pannotia White IPA

My Pannotia White IPA has been on tap for about two weeks; it seems like a great time to evaluate the beer and reconfigure it for its next iteration (and there will be another iteration!).

  • The Basics
    • Starting gravity = 1.057; final gravity = 1.012; abv = 5.9%; IBU = 50 (estimated)
  • Appearance
    • Hazy, light golden hue; head is tall and persistent, with a creamy appearance and off-white color. The beer has gotten slightly less hazy since the first tastes a week or two ago.
  • Aroma
    • Dominated by citrus, secondarily with some floral and passionfruit aroma; very clean and fresh
  • Flavor
    • Hop-dominated; very citrusy and slightly floral. Any maltiness is subtle at best. There is an extended, smooth, and slightly sweet finish for the hops.
  • Mouthfeel
    • Nicely carbonated; body is perhaps a touch thin
  • Would I brew this again?
    • Absolutely! The white IPA style is a delightful and very drinkable variant change from the overbearing single/double/triple/quadruple American IPAs that are the norm for many microbreweries. My original goal was to recapture my memories of the Italian-made Vergött White IPA. I got partway there--particularly in its appearance and refreshing drinkability--but am lacking the somewhat lemony aroma and flavor that I recall from the original. Some more sleuthing on Italian-language websites revealed indications that they dry-hopped with Galaxy hops (and possibly some Mosaic), that the alcohol clocks in at 5.5% (rather than 5.9%), and that oats are part of the mix too. I would also like a little more body in my beer. So, I think for the next iteration I will use 2-row malt instead of pilsner malt, mash at a slightly higher temperature (perhaps ~152°), add some oats, notch the alcohol down a touch, and dry-hop with Galaxy instead of Citra. I will likely maintain the first wort hopping with American hops (probably Cascade), because the background hopping on this one is about perfect.

Refractometer Calibration

This is more of a sticky note for myself than anything...I did a bunch of calculations and regressions based on my brewery setup and my refractometer, and established the following equation to convert from the specific gravity reading on my refractometer to a close approximation of specific gravity from my hydrometer:

h=1.070743072r-0.070823104
where h is the hydrometer reading (s.g.) and r is the refractometer reading (s.g.)

This equation seems to do a very good job of matching my previous values.

Note: I estimated a Brix correction factor of 1.0645 for my system.

Red Oak Ale

Most of my beers recently have been fairly down-the-middle, aiming-for-a-particular-style kinds of brews. Most have turned out quite well, but I'm really feeling the need to do something a little wild and crazy. To heck with BJCP guidelines; let's brew something interesting!

So, I searched around a bit, searching inspiration from various recipes and beer kits. Then, my eyes landed on the Fire in the Hole Ale kit from More Beer. It had everything...ample hops, ingredients I hadn't used, a different yeast strain, and even some oak chips for good measure. I modified the ingredient list a bit for what was on hand in the brew store and in my hops stash, and came up with Red Oak Ale. It's a bit of a kitchen sink beer--gotta get rid of those spare hops in odd quantities after all--but at the least it will be something different.

Red Oak Ale

  • 11 lbs. 2-row malt (Great Western Malting)
  • 1 lbs. 80° crystal malt
  • 1 lb. flaked wheat
  • 0.5 lb. Munich malt
  • 0.5 lb. rye malt
  • 0.15 lb. Carafa II malt
  • 1.15 oz. Magnum hops pellets (12.5% alpha), boil 60 minutes
  • 1 oz. Northern Brewer hops pellets (7.8% alpha), add at flame-out
  • 1 oz. Willamette hops pellets (5.2% alpha), add at flame-out
  • 0.59 oz. El Dorado hops pellets (12.6% alpha), add at flame-out
  • 0.41 oz. Magnum hops pellets (12.5% alpha), add at flame-out
  • 1 tsp. Irish moss, boil for 10 minutes
  • 2 pkg. Pacific Ale liquid yeast (WLP041), in 1.5 L starter prepared 24 hours in advance
  • 2 oz. Willamette hops pellets (5.5% alpha), 14 days dry hop
  • 2 oz. French oak chips, 7 days in secondary
Procedure
  • Because the yeast were ~2 months past prime, I used two vials and made a 1.5L starter (4 oz. DME to 1.5 L water). The starter was a little slow to krausen, but within ~16 hours it was satisfactorily foaming on the stir plate.
  • I mashed in with 4.5 gallons of water at 169°. This hit a mash temperature of 157°, which was down to 155.5° after 15 minutes and 153° after 40 minutes.
  • I added .36 gallons of water at 200°, let it sit for 10 minutes, vorlaufed, and collected 2.8 gallons of wort.
  • I added 3.15 gallons of water at 180°; the mash bed rose to 168°. After 10 minutes, I vorlaufed and collected the remainder of the wort.
  • All told, I collected 6.25 gallons of wort at 1.059 s.g. This works out to ~72% efficiency. A little lower than normal; I wonder if this is because I skipped the pH 5.2 stabilizer? Or maybe because it's a fairly high gravity recipe with a lot of flaked ingredients?
  • Once reaching a boil, I added the Magnum hops bittering addition.
  • After 50 minutes, I added the Irish moss.
  • Over 60 minutes, I boiled the wort down to 5.5 gallons; at flame-out, I added the aroma hops. These are partly randomly chosen to accentuate earthy aromas, and partly chosen to use up spare stock.
  • I cooled the wort down to ~76°, and transferred to my fermenter while aerating with the Venturi pump. I pitched the yeast, and sealed everything up. I'll be fermenting at 66°.
  • Starting gravity was 1.070, with ~4.75 gallons into the fermenter.
  • I plan to ferment for ~10 days, transfer to the keg, and dry-hop for 14 days. For the last 7 days, I'll add the oak chips (boiled in water to sterilize them). Then, carbonation!
  • I brewed the beer on the evening of 15 May 2015. Within 8 hours, the beer had krausened nicely and was fermenting along at a good clip. I expect I'll agitate it a bit in a few days (as some have recommended for WLP041) to help fermentation along.
A note on refractometer calibration
  • I've been noting that the specific gravity scale on my refractometer is not terribly reliable, at least relative to my hydrometer. For instance, the refractometer read 1.065 when the hydrometer read 1.070, and for another batch 1.049 and 1.052, respectively. I had initially assumed a 0.02 difference, but the relationship is not strictly 1:1. So, I gathered up readings from a few batches, and came up with this equation:
    • h=1.1037604457r-0.105597493
      • Where h = hydrometer reading and r = refractometer reading
  • I plan to investigate this a little more thoroughly to come up with a quick-and-easy conversion.

Summer Blonde Ale 1.1

Thanks to a few recent gatherings at which I have served my homebrew, my three kegs all kicked this past week. That means...more brewing! My Pannotia White IPA just came online this weekend (and wow is it tasty!), but I've got two taps to fill as soon as possible. So, I'm fulfilling this "obligation" first with a blonde ale and second with a "wild and crazy brew" (more on that one in a subsequent post).

For tonight's brew, I elected to rebrew a blonde ale that I did last summer. That one turned out pretty nicely, and the warm summer months are approaching, so on we go again! I made a few minor modifications, partly to account for the efficiency of my equipment but also to use up some hops I had on-hand. Also, I switched yeast strains from US-05 to WLP001.

Summer Blonde Ale 1.1
  • 9 lbs. 2-row malt (Great Western Malting Co.)
  • 8 oz. 15° crystal malt
  • 1.10 oz. Willamette hops pellets (5.2% alpha, 3.7% beta), 60 minute boil
  • 1 tsp. Irish moss (10 minute boil)
  • 1 pkg. California Ale Yeast (WLP001, prepared in 1L starter)
Procedure
  • I mashed in with 3.1 gallons of water at 160°. The temperature stabilized at 151°, was down to 148° after 35 minutes, and was down to 147° after 55 minutes.
  • After 60 minutes, I added 1.25 gallons of water at 160° to the mash, let the mash sit for 10 minutes, vorlaufed, and collected 3.3 gallons of wort.
  • Then, I added 3.1 gallons of water at 185°, which raised the mash bed to 168°. I let it sit for 10 minutes and vorlaufed.
  • All told, I collected 6.6 gallons of wort with a gravity of 1.039. This works out to 74% mash efficiency.
  • Once the wort came to a boil, I added the hops and boiled the mixture for 60 minutes. 10 minutes prior to flame-out, I added the Irish moss.
  • After removing the kettle from the heat, I chilled the wort down to 70° and transferred all to the fermenter (aerating with the Venturi pump). I pitched the starter (which I had put together five days previous; cold-crashed for two days, and decanted spent wort leaving all but ~0.5 L yeast slurry).
  • My starting gravity is 1.047, with 5 gallons of wort into the fermenter. I'll be fermenting at 65°.

Beer Tasting: Lab Bench Pale Ale

My Lab Bench Pale Ale has turned into a pretty nice brew; I did a formal tasting at the end of April (as well as a run-through with my homebrew club). Results are below.

  • The Basics
    • Starting gravity = 1.047; final gravity = 1.010; abv = 4.8%. Estimated IBU = 38
  • Aroma
    • Crisp and hoppy, as expected for a dry-hopped beer. A touch citrusy.
  • Appearance
    • Clear, rich golden hue; off-white head with fine bubbles and excellent persistance. 
  • Flavor
    • Hop-forward, only a hint of maltiness. Smooth bitterness on the finish.
  • Mouthfeel
    • A touch thin (but not overly so); excellent carbonation for the style
  • Would I brew this again?
    • I think so, but with a little modification. My mash temperature seems to have been about right, but perhaps a little carapils would help with body. I am pretty pleased with how the first wort hopping seems to have created a smooth bitterness for the beer. The aroma is also just about perfect!
  • Overall rating
    • 7.5/10
