The Flavor: Sour


Greetings citizens,

Today's flavor of the day on Sesame Street is: Sour.  The first thing that comes to my mind when I think about sour is my favorite candy, sour Warheads!  I have tried all the sour warheads products from the traditional hard candy to the breath mints and sour spray.  To my knowledge they do not make a beer yet, but they should!  My first sour beer was quite the experience: La Folie by New Belgium Brewing Company in Fort Collins, CO.  Think cherry warheads, cold, carbonated, and wrapped in a mild brown ale background.  It was my first and still stands to this day as being my favorite, at least the 2010 vintage anyways.  After buying 8-10 bottles over the course of about a year from the Brookings Liquor store at $13.99 a piece they finally ran out of that 2010 vintage.  At this time I knew that I must learn more and brew my own.  The main thing that scares me about trying to make something like this is that it is expensive for a reason, and it says so right on the bottle "Reddish brown ale fermented 1 to 3 years in french oak barrels for mouth picking perfection".  I would have to commit a $30 fermenter and about $30 of ingredients for 3 years in order to make this stuff?  My accountant brain said the NPV of a fermenter, a brew day and ingredients exceeds the return I would get in 3 years so, I had to find an easier way. 
Fast forward about a year to the summer of 2012 and I find myself consuming more and more different sour ales, and I happened upon Oarsman by Bell's Brewery of Kalamazoo, MI.  Oarsman is a light in color and body, sour mashed wheat ale.  Picture a light, tangy, lemony, tart and refreshing beer that would take everything you love about a shandy and crank it to the next level by blending it with a sour beer.   First thing I was thinking, as after every new beer style I find, is that I had to do some more research on how to make me some of my own!  My discovery was astounding, I found out that I could make this sour mash ale in not 3 years, 2 years, or 1 year, I could make this stuff in just 2 weeks for a total cost of $12 for 5 gallons.  In the words of Phil Robertson(Duck Dynasty), "Now we are cookin' with peanut oil!"  Needless to say I had to try it, and it was the weirdest brewing I have ever done.  I was quite skeptical.

I will try to keep this simple but an all-grain brewing knowledge would be helpful.
Here is what I did:
5 pounds Briess Pilsen Malt and 4 pounds Rahr White Wheat Malt mashed at 154F for the duration of the Brookings Bobcats vs. Yankton Bucks Boys BB game with a 1.25 qt/lb grain ratio.  Added the rest of my brewing water for the whole batch to my igloo cooler to lower the temp to 120F.  Toss in .9 more pounds of uncrushed Pilsen malt , flood the head space in the cooler with CO2 and cover with a few layers of saran wrap.   Come back in 48 hours (yeah, 2 days!).  It will most likely smell like your garbage can on a hot summer day, but that is a good thing. Then pull off a majority of the mash into a pot and bring to a boil and add it back to the cooler in order to raise the mash temp to 170 for the run-off(mash out).  Bring to a boil, add in just enough hops to call it a beer and boil for 15 mins.  Cool to 65F and toss in a packet of Fermentis S-04 yeast.  It finished fermenting in a couple days and I kegged most of it with some making its way into a 64 oz growler with 20 little carbonating tabs. 

Here are the results:  A murky lemonade looking, headless treat with a taste that follows the appearance.  It is everything that I ever imagined I wanted a sour mash ale to taste like and more.  I am both amazed and excited to see that this is so easy, cheap, and quick!

Intro to Fermentation


Hello all, my name is Richard Drawdy, a husband and father of one son, an employee at Daktronics, and the part that leads me to this blog is a home brewer of about 27 months now. About a year ago I began talking to Matt about his homebrewing adventures which I originally discovered through this blog.  Then a couple months ago I got the chance to brew with the AnderHoff duo.  I noticed that they are in the beginning stages of the home brewers learning curve with myself being a little closer towards the apex.  At that point I figured there may be a few things that I could lend in the way of advanced brewing tips that could be a helpful contribution to the blog.  In my tenure I have made about 300 gallons of the home made libation we all love, totaling about 50 different recipes. It's not all about volume in this art its more about quality which leads me to my first topic I would like to present in my series of initial blog posts about improving your home brewed batches: quality fermentation.



There are many things that go into producing a malt sugar filled liquid which brewer's call wort, I will focus today on handling that wort once you get it into your fermenter. There are many variables that go into fermentation: wort composition, wort temperature, yeast variety, yeast cell count, yeast health, and fermenter size.  All of this may seem like a lot to worry about and it is! But, to keep it simple you can follow these couple of steps in preparation for your brew day:
Review the specifications for your yeast. This will tell you important things like pitching rate requirements, temperature tolerance and alcohol tolerance.  Effective fermentation is easily accomplished by shooting for the middle range on each of these requirements for your batch of home brew. Once you know the pitching rate requirements for your yeast you can use calculators available at yeastcalc.com or mrmalty.comin order to propagate or know how much to buy for your specific wort. Under pitching your yeast quantity can cause the wort to finish short of the targeted alcohol content as well as increase the amount of abrasive flavors produced by the yeast. Over pitching your yeast is less harmful but can cause the yeast to produce less flavors that you may want in the finished product.
Once you have the correct amount of yeast in your wort you then will want to focus on temperatures for the fermentation. Shooting for the lower end of your temperature range will restrain yeast flavor production, while the opposite will cause flavor production, some of which may be undesirable in the higher temperature ranges.
Now that we know the basics of fermentation lets walk through an example: Northern Brewer's Dead Ringer IPA Kit. When you buy the kit you also need to consider your schedule and whether you will have the time or equipment to make yeast starters, if not you will need to buy more than one liquid pack of yeast. This kit calls for a fermentation volume of 5 gallons of wort at an original gravity of 1.064. Yeastcalc.com says that this requires 222 billion cells of yeast or a pitching rate of 11.7 million cells per milliliter of wort. The Wyeast American Ale 1056 that comes with the kit contains 100 billion cells of yeast at the day it is produced. Based on the production date of the yeast pack you would need to buy 2 or 3 yeast packs. Or make a starter with 1 packet with a volume of 2-4 liters of starter wort again depending on the yeast packet age.  I will assume that the yeast pack is 1 month old, meaning I will have 85 billion cells to start with. I will either need to buy 2 more yeast packs or make a 2.8 liter yeast starter to get to 222 billion cells needed for this healthy fermentation. Wyeast American Ale 1056 has a fermentation temp range of 60-72 F, 15-22 C. For this IPA I do not really want any yeast flavor contribution so I will shoot for 62 F on this fermentation.  In order to achieve this temperature with some consistency but there are a variety of methods available.  You could be sure that you brew during a time of the year that you have a room in your house will be the optimal temperature, or you could build yourself a fermentation control system with a fridge like I have done.



Thanks for reading, and happy fermenting! Cheers - Rich
