Reviews of English Mild v1, Design and Brewing of English Mild v2

Thanks to Eagle Rock Solidarity and Moorehouse Black Cat, English Mild is becoming one of my favorite styles of beer.  I really enjoy the layers of rich maltiness, roast, chocolate and fruitiness of the milds, especially when wrapped up in its low ABV package.  Both Solidarity and Black Cat almost taste like a scaled down Milk Stout without the lactose, which given my affinity for a good milk stout, equals awesomeness in a bottle.  

With my crazy schedule (Pregnant wife, finishing Ph.D., starting up company and working on my Post-Doc research on the side) I've found that I can't really drink a pint of a higher ABV beer in the evening, as they get me drunk and make me sluggish the next day.   In order build up a yeast cake for a massive Imperial Milk Stout and produce a stash of session beer, I brewed an English Mild a couple months back.  My local homebrew shop had some Briess Mild Malt on hand, and I figured it would be interesting to try and make a Mild using actual Mild Malt (Granted this is Breiss' version of it, so most likely not uber traditional).

I decided I wanted a fairly biscuity, thick (yet drinkable), slightly chocolatey and roasty Mild.  In order to really produce some strong biscuit notes I went with a large percentage of Breiss Victory Malt on top of the Mild Malt Base (Mild malt tastes a touch biscuity as well, with a slight sweetness and a chewy mouthfeel).  To up the body and give it a little caramel and toffee like sweetness I went with 7.5% English Medium Crystal (Simpson's) and 5% English Dark Crystal (Simpson's), with 5% English Pale Chocolate Malt for some roastyness and biscuity, milk chocolate like flavors.

The beer was mashed high (158F, Brew in a Bag) for 45 minutes, 90 minute boil, pure O2 (60 seconds) and fermented as a split batch at 62F (5 days), 70 F (3 days) with Wyeast 1968 and ECY Mild Ale.  

While the WY1968 produced a nice beer it lacked some malt sweetness and caramel notes so I bottled primed with turbinado.  The ECY Mild Ale was unfortunately infected from the get go (the original vial and starter smelt lactic) and as a result, I racked it into another fermenter, blended with some extra English Barleywine from a keg (1.5 gallons each) and a can of Lyle's Golden syrup and then pitched 1 pack Roselare, 1 pack Lambic blend (both sitting in fridge) and 1/4 pack BugFarm VI to make an impromptu sour (Souring as we speak).

The final recipe with details is below:

After the WY1968 Mild (Batch 60) spent 2 weeks in the bottle I cracked a bottle for review:

Appearance:  Crystal clear.  Dark ruby/brown with a big creamy head that dissipates quickly and leaves sticky lace on the glass.

Aroma:  Coffee, chocolate, roast, cola, bread crust, nutty malt, brown sugar & molasses, with a slight rasin and prune aroma and minimal fruity esters

Taste:  Light cola and coffee with moderate amount of bread crust upfront that fades very quickly into brown sugar and light roast, with a touch of smoke/flint and woodyness in the finish.

Mouthfeel: Thin!  Slight pricklyness in finish, with a tiny bit of astringency.  Carbonation is low and spot on.

Overall/Future Versions:   This beer, while tasty and flavorful, isn't quite where I want it.  It needs to have a much fuller mouthfeel (Mash higher, more crystal) with some caramel sweetness and in general more malt complexity.  Upping the roast and chocolate character a touch, should help balance out the increased sweetness and body so as not to come across as cloying.  A touch more ester production would help complexity even more.


In addition to my own review I've attached BJCP scoresheets from the Maltose Falcon's Mayfaire Competition (Judged Blind) and from a friend's blog, Kettle and Cellar.

A while back, a recipe for my Vanilla Chai Latte (VCL) Imperial Milk Stout was published in the homebrewing section of Beer Advocate Magazine.  The VCL was judged blind in the Maltose Falcon's Doug King Memorial Specialty and Experimental Beer Competition by Drew Beechum.   Drew commented on my scoresheet that he really liked the beer and asked for a recipe, so I of course contacted him and eventually it lead to the recipe being published in the BA Magazine (Thanks Drew!).  All that being said, Riley (Author of the Kettle and Cellar Blog, and JimmyTango on BA) was curious about the VCL so we set up a homebrew trade.  Below is Riley's review of the v1.0 Mild followed by scoresheets from the Maltose Falcon's Mayfaire Competition.

Barfdigg's English Dark Mild


This was the first beer Kel and I opened from the beertrade. It was a mellow Sunday afternoon and the beer was great daytime drinker—although it would have been more fitting on a rainy day.

Appearance: Clear brown-to red with a thin off white head that looks pretty and creamy but falls quickly to a thin film… but can’t blame a low carbonation beer for being a little shy.

Smell: Rich coffee and bread crusty notes with some roasted nut tones and a hint of cola sweetness in the background. Pretty aromatic for a small beer, with a complex depth that fades from fruit to roast and a lot of layers in between.

Taste: Smooth and rich with more toffee than the nose. Nicely full without being too sweet (the beauty of the style when done right IMO). Rich and nutty… almost a hint of poppy seeds. Finish is long and cozy, clean and light, pleasant.

Mouthfeel: Light bodied with light to moderate carbonation. I’d say it could use a bit more body—preferably more “cheweyness” from oats or flaked wheat/barley, but some extra “stickyness” from more c-malts would be fine too.

Overall: I love the layers of yeast and malt. It is quite captivating for such a low gravity beer. I’d love to know what is lending the subtle herbal and cola notes, and I think the super low bitterness (low even for the style) is a nice touch.

If it were my beer what would I tweak? It’s hard to say exactly because I don’t know what the recipe looks like, but I’d probably add some [more?] oats or up the mash temp quite a bit to try to get more body out of it. And, although I generally stay away from it I may make the [switch?] to Marris Otter as a base in an effort to bring even more malty flavors to the party. Really though, I think the yeast choice, malt bill, hopping, and water treatments are right on.

Any of y’all that haven’t had the pleasure of drinking an English Dark Mild, go find one!



BJCP Scoresheets for English Mild Ale from Maltose Falcon's Mayfaire Competition:





So with all of that being said, I'd really like to rebrew this beer but make some changes to the grain bill to add complexity to the beer. As noted above in Riley's blog, the BJCP scoresheets and my review, this beer needs some increased malt flavor/richness and maybe a little more sweetness.  Additionally, I feel like adding a touch more creamyness and a little more coffee and chocolate roastiness to the beer will help round it out on top of the increased malt sweetness/richness I'm shooting for (something I've noticed in Eagle Rock Solidarity, a kickass dark mild brewed by a local brewery, also featured on Brewing Network Can You Brew It).

In order to add some malt sweetness and richness, I'll be switching from Briess Mild Malt as the base malt to Fawcett/Simpsons or Muntons Marris Otter (I love Warminster Floor Malted, but it gives off this peanut butter cookie flavor that I feel would clash with everything else going on in this beer).  The Briess Mild Malt really didn't add much flavor, maybe a touch of toastiness (grain doesn't taste like anything).  Fawcett/Simons/Muntons Marris Otter all have a very nice, yet hard to describe, richness (Nutty, sweet, melanoidins) to them, which should make a nice base for this beer.  Additionally, I'll be upping the English Medium Crystal from 7.5% to 10% to produce a little more body and a touch more sweetness and malt complexity.  Will also be increasing the mash temp up to 160 for this one, to try and add some more body (NOTE:  My beers tend to finish a little drier than Beersmith predicts, so I'm constantly mashing way higher than some of you guys out there).

The other big changes include the addition of golden naked oats at 4.5% of the grist and a slight reduction in pale chocolate malt (5% to 4.5%), and the inclusion of Franco Belges Kiln Coffee malt at 1.3% of the grist.  I find the golden naked oats aid in head retention and give the head a nice creamy, shaving cream like consistency while adding minimal sweetness, almost like an oat version of carapils or crystal 10.  The inclusion of Kiln Coffee malt should up the roast factor just a touch and lend a little more aggressive chocolate and coffee notes to the beer.

On the yeast front, I originally planned to replicate my earlier strain choices and do a split between ECY Mild Ale and Wyeast 1968, however the fresh ECY Mild vial I picked up was again infected when I did a starter of it so I scrapped the idea of using it in this brew.  Instead I picked up some White Labs Bedford British (WLP006 Platinum), as I remember really enjoying the ester profile of this strain when I tried it at White Labs (Lightly fruity, medium attenuation, slight mineral character).  The Wyeast 1968 is a great yeast, and one of my go tos for English Ales, so it will serve as the benchmark.  For this batch I may under pitch slightly and fermenter around 72 F to promote a little more ester production, as some fruitiness from the yeast could really make this a well rounded and interesting beer.

Here is the updated English Mild 2.0 Recipe.  It was brewed on 08/10/2013.

Berliner Weisse Test

NOTE:  Brew day should be last weekend in July or first weekend in August.  Will update with brewday notes and pictures, and review when finished.

Berliner weisse is one of my favorite sour beer styles.  On a hot summer day in Southern Cal the spritzy carbonation, lactic-lemony tartness, grainy wheat character and fruitiness really seem to hit the spot.

About ten months back I attempted my first Berliner as a partigyle beer from a large batch of single decocted Bavarian Hefeweizen I was preparing for an event (The Caltech Sausage Fest... yes, that is seriously an event).  I ended up blending some of the first and second runnings to hit an O.G. of 1.028, and after a 15 minute boil with some EKG to hit 8 IBU, chilled it to 100 F and pitched 2 vials of White Labs Lactobacillus bacteria (WLP677).  I kept the beer around 100 F for 7 days before slowly cooling to 70 F and pitching 1 packet of Wyeast German Ale Yeast (1007).  After gravity was stable for 7 days (1.006), I racked to a bottling bucket, pitched Brettanomyces Bruxellensis and primed to 2.5 volumes of CO2 assuming that the gravity would drop to somewhere around 1.000 (It did).  Upon tasting the beer at 3, 6 and 9 months, it had a great effervescent carbonation, floral/fruitiness and grainy wheat character, but just a touch of tartness.

I found this quite interesting as I assumed pitching Lactobacillus bacteria would produce a good deal of lactic acid.  However, when doing a little research I found some interesting facts about Lactobacillus metabolism (Excerpt from Wikipedia, followed by information from http://textbookofbacteriology.net/lactics_2.html):

Many lactobacilli are unusual in that they operate using homofermentative metabolism (that is, they produce only lactic acid from sugars in contrast to heterofermentative lactobacilli which can produce either alcohol or lactic acid from sugars) and are aerotolerant despite the complete absence of a respiratory chain[citation needed]. This aerotolerance is manganese-dependent and has been explored (and explained) in Lactobacillus plantarum. Many lactobacilli do not require iron for growth and have an extremely high hydrogen peroxide tolerance.

According to metabolism, Lactobacillus species can be divided into three groups:

Obligately homofermentative (Group I) including:
L. acidophilus, L. delbrueckii, L. helveticus, L. salivarius

Facultatively heterofermentative (Group II) including:
L. casei, L. curvatus, L. plantarum, L. sakei

Obligately heterofermentative (Group III) including:
L. brevis, L. buchneri, L. fermentum, L. reuteri

Heterofermentative (Left) and Homofermentative Metabolism (Right)
From http://textbookofbacteriology.net/lactics_2.html

                            Heterofermentative                                            Homofermentative


Heterofermentative (Heterolactic)= One mole of glucose is converted (via the (via the pentose phosphate pathway) into equimolar quantities (1 each) of CO2, Ethanol and Lactic acid.

Homofermentative (Homolactic) = Under conditions of excess glucose and limited oxygen lactic acid bacteria can produce lactic acid via the catabolism of one mole of glucose (via the Embden-Meyerhof pathway) into 2 moles of pyruvate, which is eventually reduced to lactic acid.

Note that the Whitelabs WLP677 is referred to as Lactobacillus bacteria, which only lists a genus (Lactobacillus) and not a species (delbrueckii), which to me suggests a blend of species or un-named subspecies.  Information from White Labs on the Mad Fermentationist's Blog (http://www.themadfermentationist.com/2012/06/100-lactobacillus-berliner-weisse.html) suggests that WLP677 is indeed heterofermentative and can produce lactic acid, CO2 and alcohol, in contrast to the Wyeast 5335 Lactobacillus delbrueckii (Genus and Species) that only produces lactic acid.  Interestingly, a recent post on the Mad Fermentationist's blog reviewing his 100% WLP677 Lactobacillus fermented berliner weiss produced a similar result to my beer, namely a nice nose with some lactic acid like aromas, but a taste that falls pretty flat in the acid department (e.g. almost none).

One other note of import from the Mad Fermentationist's blog comes from Chad Yakobson at Crooked Stave, that mentioned "Lacto produces a protein degrading enzyme which is active at higher pH values. By lowering the pH (e.g., acid malt, or food grade acid) to 4.5-4.8 pre-pitching you can yield better foam stability. I decided to skip this technique on my first attempt however to see if it is a necessary step."  Interestingly, the cited proteolytic activity is of critical importance for lactobacillus survival, and is important in flavor development in cheese production.  In order to grow to high cell density some strains of lactobacillus require amino acids in quantities not available in their growth medium and thus must secrete proteases to liberate the amino acids from proteins.  In cheese making this apparently is responsible for the production of desirable flavor tones.   I'm curious if the strains available to homebrewers are auxotrophs (Prototrophs can synthesize all required amino acids themselves) and are required to secrete proteases for cell growth and survival.  The notoriously poor foam stability in Berliner Weiss could most likely stem from the secreted proteases required for cell growth if lactic acid bacteria used for fermentation of Berliner weisse are indeed auxotrophic.

So, with all that long winded inner monologue about lactic acid bacteria, WTF am I going to do for my Berliner Weiss Test??

I'd really like to brew a series of Berliner Weiss' with varying fermentation and microbe/yeast profiles in order to find the sweet spot for my Berliner Weiss': very dry and effervescent, with sharp lactic/lemonade like sourness, moderate fruitiness and a nice grainy wheat flavor.  In order to hit that mark I'll be utilizing the following strains:

Wyeast German Ale Yeast (1007)
Wyeast Berlinerweisse blend (3191 PC)
Wyeast Lactobacillus (5335)
White Labs Berlinerweisse blend (WLP630)
White Labs Brett Clausenii Trois (WLP644)
White Labs Lactobacillus (WLP677)
Non-fat Yogurt Mixed Culture

The use of Brett Clausenii Trois might be a bit weird to some, but I like its fruity aroma and mild Brett character, so I'll be using it instead of the normal Brett Clausenii (Lambicus used in the first Berliner was too funky/horsey/hay).  Additionally, the use of a mixed yogurt culture may seem odd, but it is a source of lactobacillus (granted its not a pure culture), and provides an additional source of lactobacillus not produced by Wyeast or White Labs.  While many people swear by sour mashing in corny kegs, I'm concerned with repeatability, so will not be performing sour mashes in this experiment.

As far as the grain bill, I'm just doing a simple 23 gallon extract batch with a mini-mash.  24 Gallon boil volume with straight up Wheat Extract LME & DME (65% Wheat, 35% Pilsner) with a mini-mash of Malted Wheat and Torrified Wheat for just a little extra dextrin content and raw wheat flavor (Not traditional, but I like it, so fuck tradition).  Will be doing a short 30 minute boil with EKG hops to hit 5 IBU, then chilling down to 100 F for the Lacto ferments and racking off, then chilling the remainder down to 75 F for the Berliner Weisse Blend fermentations.

Heres the breakdown of the split batches and fermentation schedule:

5 gal - Wyeast Lacto and cup of non-fat yogurt for 7 days, White Labs Lacto to Finish
1 gal - Wyeast Lacto for 7 days, White Labs Lacto to finish
1 gal - Wyeast Lacto for 7 days, White Labs BrettCT to finish
5 gal - Wyeast Lacto for 7 days, White Labs Lacto 7 days, White Labs BrettCT at bottling
5 gal - Wyeast Lacto for 7 days, Wyeast German Ale Yeast to finish, White Labs BrettCT at bottling
1 gal - White Labs Berlinerweisse Blend
1 gal - Wyeast Berlinerweisse Blend
Prior Batch - White Labs Lacto for 7 days, Wyeast German Ale Yeast to finish, White Labs Brett Lambicus at bottling

All batches containing Brettanomyces added at bottling will be primed to 2.5 volumes CO2, all batches without Brettanomyces will be primed to 3.0 volumes of CO2.

Note Additional volume of wort (4-5 gallons) will be innoculated with BugFarm VI and a bunch of maltodextrin to make a Golden sour that will be racked onto homegrown peaches in a couple months.

Notes:
------
Original batch using White Labs Lacto only, followed by German Ale Yeast then Brett Lambicus at bottling.  Batch wasn't sour at all (almost like a funky lager), which seems to be common amongst other people who used only White Labs Lacto, whereas Wyeast users using their Berliner Blend have got a good deal of tart.  Also, pitch brett trois or claus next time instead of lambicus, to get more tropical fruit and less barnyard funk.  I still have bottles of White Labs Lacto, Wyeast German Ale and White Labs Brett Clausennii Berliner to compare against.
