Review: Heart Murmur - Atrium

It is always fun to test different ingredients and how they work and produce different attributes. A single malt, a single hop, a single yeast strain. Different combinations can produce different results. In this case, a single change of yeast strain produces vastly different results. One batch of wort, 100% Great Western Pale Malt, 3.0 oz of EKG hops to finish the beer (Magnum for bittering), to make 8 gallons of 1.052 wort, split two-ways. One received WY 1469 West Yorkshire, this one WY 1968 London ESB. It is amazing how the two yeast produced 2 vastly different beers, one malty, complex, hoppy, but not bitter, medium body, yet dry and light on the tongue; very impressive beer. As the following review shows, the second yeast, not so much, bitterness is pronounced, as are the hops, no malt character at all, dry, thinnish, light fruity esters, phenols, acetaldehyde. As with the West Yorkshire, the name comes from a flutter in a heart test called a Heart Murmur, which triggered some more tests; seeing as I was using all EKG hops, I decided to run with that as the name. Atrium comes from the location of the heart, in the lower section of the heart as is London in England when compared to West Yorkshire (the yeast for the other half of the beer).

Look: Pours a light orange with 1/2 finger pure white head, brilliant clarity, head fades slow to a thick cap that sticks around and leaves a great lace throughout.

Aroma: Hoppy, grassy, floral hops, light nuttiness, not much malt character, hoppiness is pronounced. Light banana esters, spicy.

Taste: Tastes of hops, floral, spicy phenols upfront and carry through, lots of cloves and pepper, clean malt but not much more. Banana, and some other light fruitiness. Phenols dominate the palate, covers up what should be there, wish there was more of a malt backbone.

Mouthfeel: Bitterness is pronounced, malt is missing, light, somewhat bland and watery, dry phenolic finish with a lasting bitterness.  Acetaldehyde leaves a sticky mouthfeel, and astringent as well.

Overall: Not at all the blend of malt and hops, complex, balanced beer that the same wort produced with the West Yorkshire Yeast. Amazing how different these beers turned out. This beer has the bitterness and tons of flawed fermentation characters thanks to the brewery pitch of hop sludge. The more I drink this version, the more I want to pour it out.

Review: Heart Murmur - Ventricle

I honestly am very impressed with this brew. The more I drink it, the more I think it needs to become my house beer. It's simple, light, balanced, and delicious. It's actually quite complex for being only one malt and one hop. I will be posting a second review of "this beer" soon. I brewed 8 gallons of this wort and split it to 2 different Better Bottles and pitched 2 different yeast strains. This beer is all Great Western Pale Malt (3L) to 1.052, mashed for 1 hour @ 147*F. It has a bittering charge of 1oz Magnums for 60 minutes, and an ounce each of EKGs @ 15, 5, and FO (8 gallons). FG was 1.009 for an ABV of 5.7%. This batch was fermented w/ WY 1469 West Yorkshire. During an EKG for my blood pressure spike a few months ago, there was a flutter in the test called a Heart Murmur, which triggered some more tests; seeing as I was using all EKG hops, I decided to run with that as the name. Ventricle comes from the location of the heart, the ventricle is in the lower section of the heart as is West Yorkshire in England when compared to London (London ESB was the yeast for the other half of the beer).


Appearance: Pours a hazy golden-orange with a tight, pure white 1/2 finger head that persists and fades to a thick cap on top. Lacing is thick and sticks nice along the top.


Aroma: Smells of peaches, nectarines, and bananas, floral hops, faint citrus fruits, grassy, white pepper, bread dough, yeast, honey, herbal.


Taste: Taste mirrors the nose, floral hops, fruity, not yet ripe apricots, spicy, grassy hops, bread dough and yeast, floral alcohol, honey.


Mouthfeel: Medium-Light body, light on the tongue but not thin, dry finish, lingering bitterness in the back of the throat. Crisp and refreshing. Carbonation is light.


Overall: Very impressed. Great marriage of malt and hops, complex hop and malt character for a SmAsH brew, yeast creates an amazing fruity bouquet and draws out a depth to the malt, the bitterness is subdued, yet balances well with the dry finish. Very refreshing. The yeast haze is not to style, but I could care less about clarity.

It's Been Awhile

As you can easily see, it's been awhile since I posted on the blog, and I thought that an update might be in order. Here are a few things I have been working on and brewing. After the last brew when I tested my efficiency, stabilized my system, and began to work on my own brewing "software" a lot has happened.

I brewed a partigyle Wee Heavy with Heather Tips and a Scottish 90- that was aged on Oak and Laproiage Islay Scotch. The beers didn't turn out as I'd liked. They are way too fruity and not very malty. The 90- is much further down this line than the Wee Heavy. All of this is recipe based. I added both c120 & Special B which added tons of fruit and none of the caramel and subtle dark fruits I was looking for. The peat malt came off quite phenolic. Using 1056 subdued any maltiness I was looking for and through off lots of fruit. I have already reworked the recipe to remove the c120 and Special B, and added French CaraMunich and CaraVienna for light caramel and toasted sugar, and British Dark Crystal for more of the same, and went for 1968 London ESB to pull of a heavily malty character.

I also brewed a second partigyle, a 10.6% Imperial Stout with Chipotle & Cherries, and a Session Stout with Orange and Cinnamon. The big beer was fermented for 3 1/2 weeks, then aged 1 week with Chipotle and 3.75# Sweet Cherries, then another 3 weeks with just the cherries, then aged 1 more week on its own before bottling. It is quite smooth, fruity, dark, rich, chocolaty, and a slight roast. The second beer was quite devoid of character. I took a tip from Gordon Strong and cold steep some more Chocolate Malt, C75, and Black Patent, boiled it with more orange zest, and added it to the fermenter. I also added Malto-Dextrin at bottling for some more body and also offset all the oil from the orange zest so there is still great foam and head retention.

For Christmas I got my refractometer and and an aquarium temp control unit (I will post more about this in another post). I also got a second Better Bottle which was great for my next brew session. I did a "SmAsH" (Single Malt and Single Hop) type beer. I say type because I used Magnums for the bittering addition since EKGs are low in Alpha Acids and way too expensive. I used Great Western Pale Malt, and finished the batch with 3oz of EKG hops in the last 15 minutes of the boil. I then split the 8 gallon batch into 2 Better Bottles and pitched 2 different yeasts: WY 1968 London ESB and WY 1469 West Yorkshire. Come end of fermentation I used the new temp controller to up the temp for a Diacetyl Rest. I then crashed the beers to clear them. The whole thing went great, but I ended up under carbonating them since the app calculates based on temp and I used the crashed temp not the ferment temp.

My library finally got Farmhouse Ales after a year of waiting for it. While reading it I brewed a simple Saison using the WY special Farmhouse Ale strain. I mashed at 147*F, the same that I did last Summer when I brewed my two Saisons using the Dupont strain WY 3724 Belgian Saison, but the beer didn't finish as low as I had hoped (the 3724 took the beers down to 1.004 & 1.005, 3726 to 1.008). After a week in the Better Bottle at a constant 75*F, I primed and bottled in champagne bottles for added stability against the higher carbonation and the possibility that the beer might not have been finished at bottling.

I have also made a lot more adjustments to the brewing spread sheet I created. I added a refractometer adjustment section that takes the Brix and calculates OG, efficiency, and once fermentation is finished converts for alcohol to give FG, and ABV. I also added all of the malts with gravity, Lovibond, and cost from the homebrew shop as well as flavor descriptions. I was able to get a list compiled of all the hops in one of the fridges with all the Alpha Acids. I will be adding the cost and flavor aroma profiles for all of the hops as well and adding the second fridge's stock as well.

I also used my temp controlled fridge to maintain a constant 71*F to carbonate the Saison and my Imperial Stout. I will be posting some taste reviews soon on all these beers once they are carbed up and ready, so be watching for these blogs as well as a how-to-build your own dual stage temp controller for $40 (why pay $150 for a Johnson or Ranco).
