The Brett Tasting: comparing Brett types, pre/post fermentation additions

Standard

Blind tastings are fun with friends

Here is another section of my journey into souring beers.  For this part, I really wanted to focus on Brettanomyces and the impact it can have on beer.  While Brett is not the main souring organism in sour beers, I have heard far too many different opinions, so I decided the only way to really grasp what this yeast does is to try it myself.  I decided to make 5 one gallon batches (X, Y, 1, 2, 3). Of these 5 batches; Y was the control with only Saccharomyces, X was Brett B added after Saccharomyces fermentation was complete, 1 was only Brett L, 2 was only Brett B, and 3 was both Saccharomyces and Brett B pitched together at the beginning of fermentation.  All Brett was from Wyeast.

tastings:

Y (control): a mild flavor with light chocolate, roast, and fruit flavor. some bread character with a slit astringency. big bodied

X and Y

 

X (Brett B added after Fermentation): a light cherry citrus nose with hints of strawberry, some cardboard in the taste but the flavor stands out more. chocolate in the front and a solid head. mild astringency

1 (Brett L only) Smells like sour strawberry and Worcester sauce.  The taste was reminiscent of ketchup and chocolate. no head retention

2 (Brett B only) An acetic hint in the nose with the same citrus cherry character.  Tasted very chocolate and was mild and balanced. best beer!

1 and 2, 3 was so gross that there is no pic, just bad memories

3 (Brett B and Sacc pitched together) smelled and tasted like vinegar. sharp acetic. ack. vinegar!

These beers were vastly different, more than I would have thought.  I can still run through this experiment two more times, can’t wait to see what changes.

Citrus IPA: version $#!@

Standard

My.p.a.

This is a style of beer that I have been working on for the majority of this year. I think I am finally honing in on a very smooth IPA that focuses on late hop additions to give wonderful aroma but doesn’t hit very hard with bitterness.  A very hoppy beer that you can also double as a guzzler.  I’ve really fallen in love with using Galaxy hops for bittering hops, then a melody of Citra, Cascade, and Galaxy in the last 15 minutes.  Dry hopped with 2 ounces of Citra to really bring out the citrus, grapefruit, and lemon character.  I used British Ale 1 from Wyeast, which is my preferred yeast for IPA’s, due to its ability to emphasize hop characteristics in a beer.

Citrus IPA Tasting:

Nose:  The scent comes up in the front with Citra characteristic, big lemon and citrus scents with some grapefruit underneath.

Appearance:  Very cloudy with an amber brown color.

Taste: The beer begins with a smooth round bitterness that blends into a lemon/grapefruit flavor.

mouthfeel: medium bodied, more bitter than not, but very easy to drink.

overall: This is the way it should taste.  Easy drinking citrus fruit that is mild enough to drink a few pints.    8.3/10

Brewing with Potassium Metabisulphate and Potassium Sorbate

Standard
Perhaps it was during a Basic Brewing Radio episode,  maybe it was a wine making class I took at Brooklyn Homebrew, or simply having a roommate that is a sommelier, but treating beer like wine is an approach that i have been interested in using for the better part of a year.  In wine production, sometimes after fermentation is complete, chemicals like Potassium Metabisulphate (KMS)(K2S2O5) and Potassium Sorbate (C6H7KO2) are used to not only stabilize wine, but also to slow oxidation.  If anyone that you know is allergic to Sulfites, their trouble with wine is caused from this practice.
The purpose of adding KMS is to add self life to wine, since this treatment kills off lots of microorganisms, but it also slows the process of oxidation, which is tremendously important when aging wine for decades.  Potassium Sorbate stops yeast replication, so even after treatment, fermentation can continue, but the yeast do not reproduce and they eventually die.
For my first step into this technique, I brewed a basic wheat beer.  Once fermentation was done, I then treated 2.5 gallons of the batch with both KMS and Potassium Sorbate.  I made a chunky puree of fresh cherry’s from the corner store with about 2 lbs of Cherries and 2 cups of white sugar.  The puree went into both batches of beer.  The treated beer ended up with a Final Gravity of 1.014, while the untreated beer finished off at 1.011.  To treat the 2.5 gallon batch, I used 3/4 teaspoon of KMS and 2.5 teaspoons of Potassium Sorbate

Untreated (left) vs Treated (right)

Tasting of Treated vs Untreated:

Untreated:

appearance: a hazy pink that has a very white head.  There is almost an orange hue to the pink

nose: A very light scent of wheat with undertones of cherry

flavor: very light in flavor, a slight hop bitterness slips into a dry finish of wheat and cherry.

mouth feel: nice and balanced with a light body, the head does leave quickly but the carbonation is medium

overall: very pleasant summer beer.  The balance of the wheat and cherry works really well and the dry finish.  7.5/ 10

treated:

appearance: the head stays around longer than the untreated beer.  Color is identical

nose: Very similar to the untreated beer, but a very very slight chemical scent is at the end of the nose

Flavor:  that’s definitely sweeter than the untreated. The white sugar sweetness removes the dryness from this beer completely.  The wheat character is also faded.  The Cherry perception is increased.

mouthfeel: a rounder body with that chemical taste that is nearly undetectable. Medium bodied and the carbonation seems higher.

overall:  This worked better than I thought it would, the white sugar and the slight chemical flavor really brought out the carbonation and the cherry flavor.  Next time I will use a different sweetener and less chemicals, but this was a worthwhile endeavor.  This opens up very many possibilities!!!!

This process definitely worked, but it needs a lot of tinkering to make beer that is truly outstanding.  Luckily, I learned a whole lot about this process on my recent visit to Sam Adams. The end product I am hoping to make is a fruit beer that actually tastes sweet enough to be considered a dessert beer, but one that tastes very similar to the fruit used.  This could also really help in my cider, which I have yet to be fully satisfied.  Much more to come.

“Coaching” Session at Boston Brewery

Standard

One of the perks of winning last autumn’s Brooklyn Wort was a one on one coaching session with an employee of Boston Brewing. By the way, the next Brooklyn Wort is being held in Manhattan in October and entries start Aug 11 for the preliminary round.  Details are here. (http://www.brooklynwort.com/)

I was offered a bunch of options, like a phone conference with a marketing specialist, but I was really interested in speaking with a brewer that could help me out with some of the more experimental things I’m playing with in my kitchen, I mean brewery. I was hoping that one of the biggest Micros would be willing to let me take up an hour of time to really pick a pro brewers brain.

After months of failure trying to work out a date that I could make it up to Boston to actually get face time with someone, summer finally came to my rescue.  I grabbed two friends who happened to have a weekday off and drove up to Boston.

Rolling up to the “Boston Brewery” I was immediately taken back by how small the scale was.  It turns out that they only use a 10 barrel system up in Boston, be it a nice one, the vast majority of their beer is brewed at two other major breweries in other parts of the country.

that’s it?

The shock of that quickly wore off when I learned that the Boston Brewery is responsible for their cask room releases.  The brewery is all set up for nice tours and cool pictures with plenty of history about Sam Adams and lots of awards that they have won hung above.  I would recommend a visit for someone who hasn’t really toured breweries before, you get to smell hops, check out grains, and walk the floor of the brew house.

big barrels!

Luckily, the majority of my visit was spent with Grant,  a recent addition to Boston Brewing, who is one of the brewers there.  After a few minutes, Grant figured out that I wasn’t there for some fun chat about pitching rate, but that I had a few more in depth questions that I would like to discuss.

Grant dropping knowledge

The talk very quickly turned into a great coaching session with ideas being shared about wild yeast identification and pH adjustment, with a little bit of info about KMS and stabilizing bigger beers.  Having someone with this kind of brewing knowledge really explain some of the science behind my ideas essentially leapfrogged my experiments about 2 years forward.  On the way out, he even hit me up with a couple of online resources that are exactly what I was looking for.  Grant made the four hour drive worth it.

This experience really renewed my affection for Sam Adams.  Sam was one of the first Micros that I ever tasted and many times, it was their brew that was my first exposure to different styles of beer.  Having them treat me with such a high level of respect and openness really boosted this beer back to the top of the pile for me. I know what I’ll be drinking next time I’m at a normal bar.  Much more on the information that I learned about in the coming posts, I hope Sam Adams starts a beer school!

Many thanks must be said to both Michelle and Grant.

Thai Tea Pale Ale (extract)

Standard

A good friend of mine wanted to get one more batch of brewing in before he moves far far far away to Mississippi and becomes a father.  In a recent adventure, he stumbled upon a thai iced tea that was simply splendid.  He decided to brew an extract pale ale with the thai tea.  A pretty straight forward brew day, with only 1 hop addition of Galaxy at 60 min made this one of the easiest brew days I have had in a very long time.  The tea went directly into the secondary fermentation after we brewed a strong cup of the tea.  We brought it up to a camping trip and the keg went quickly.

Thai tea pale ale

appearance: a light orange brown color that is hazy. poor head

nose: a bunch of esters, but also a lot of tea and mint scents, kind of twangy

flavor: an earthy flavor that is a combination of the full flavored tea and the Galaxy hop bitterness, while dry, it is pleasant.

mouth feel: the tannin pushes the bitterness to a bit of astringency, but is still a very drinkable beer.  medium bodied and needs more carbonation.

overall: not bad for an extract brew. next time, I would like to dry out the beer, ease up on the tea, and hop with an english hop like Willamette. 6.0 / 10

How gose it. Weird beer tasting

Standard

This beer is my first attempt at brewing a Gose beer, one of the few german beers that has ingredients outside of the Reinheitsgebot, the german beer purity law. It is a pleasant sour beer with salt and coriander, but I used Acid Malt for the first time. Kind of a weird flavor, but delicious for a sour that I brewed only a few months ago.

How Gose it

appearance: A golden straw yellow with a slight haze, but not cloudy. A big thick white head sits on top and hangs around for awhile

nose: Lemony and wheaty. a mild funkiness underneath

taste: A sweet wheat flavor is the foundation of a salty lemon character with a slight tartness. A definite funkiness underneath leaving the flavor a bit big for this style

mouthfeel: big bodied and very highly carbonated.  I would prefer this a little dryer.

Overall: not terrible for my first attempt of a weird beer. 4.5/ 10

The Arrival of Summer, Pineapple IPA Tasting

Standard

This last month has been a hectic one.  The end of the school year is always a fun time and with the month of June comes a real urge to drink some awesome fruit beers.  Being a beach bum summer guy, I really enjoy a whole bunch of tropically influence beers, and this is my latest attempt at one.  This beer is a citrus hopped IPA with around 95 IBU’s of Warrior/Citra/Pacific Gem being added predominately in the last 15 min of the boil.  After fermentation, I chopped up a whole pineapple that I had let “ripen” for about 1 -2 weeks and put that into a keg with the IPA.  A month later, I transferred off the beer and tapped it, here is what it tasted like:

Pineapple IPA

Appearance: A honey/ straw color that is semi clear with just a slight cloudiness, poor head retention, but highly carbonated

Nose: A big citrus nose with the Pineapple shinning brightly.  Mango and apricot undertones.

Taste:  A light beginning with a slight hop bitterness coming forward, followed by a big tropical finish.  A bitter pith of grapefruit and tart pineapple end into a dry finish.

Mouthfeel: Balanced, but big.  The dryness causes the taste to linger.

Overall:  a bit too dry for what I was going for, but for a highly hopped IPA, it was pretty delicious.  This will go great at the beach or a BBQ.  7/10.  Add a lot more specialty grains next time.
