All Grain Brewing Made Easy

Traditonal homebrewers who make the switch to all grain brewing (no extract syrup) have fairly complex setups with at least two, but more likely three vessels: a hot water tun (holder), a mash tun, and the brew kettle.

Being that I live in a 600 sq. ft. condo, this isn't really feasible for me. So I did some research and found out about an innovative technique originated in Australia called Brew in a Bag.

In essence, instead of mashing and sparging (rinsing) the grains in a separate vessel, I used a $2 nylon mesh paint straining bag to mash the grains in the full boil volume of water in my brew kettle. Join me on my adventure...

Brew day starts like any other: sanitizing, getting ingredients ready, weighing out hops, etc.

On this brew day, I was trying a Kirin Ichiban clone, using 4 lbs of American 6-row barley and 1 lb of flaked rice adjunct, 1 oz Hallertauer Hops, and dry lager yeast (to save a bit o' green).

Since we are using flaked rice, this will require a multi-step mash to adequately break down the fermentable sugars in our grains. The first step is to heat up the strike water that the grain will be added to. I want my final volume into the fermentor to be 2.5 gallons, so I have 3.5 gallons in the brew kettle to start to compensate for the grains soaking up water and whatever will steam off during the boil.

As you can see, the paint strainer bag fits nicely over my 5 gallon brew kettle. Once the water is sufficiently heated, we dump in the grain and stir, stir, stir.

My lager recipe call for rests at 122°, 140°, 158° and mash-out at 170°F. Traditional brewers accomplish these rests by starting with less water and adding more hot water as they go along. But I just used my stove top and the last few minutes of one rest to ramp up to the next one. Seemed to work ok.

Once the mash is complete and most of the fermentable sugars have been steeped out of the grains, we simply lift the strainer bag out of the brew kettle and the sweet wort is left behind. I put the moist grains in a colander resting on top of my brew kettle and let it drip for a few more minutes.

After that, brewing proceeds as normal, with three hop additions splitting up the hour-long boil.
After the boil, I chilled the wort off in the sink. I may need to buy a bag of ice for my next brew, since there is a lot of thermal mass in there and just sitting in cool sink water led to about a 45 mintue wait until it had reached yeast pitching temperature.
Since this is a lager, I let it begin fermentation for one day at room temp, and then stuck it in the fridge. Hopefully this will produce a clean, crisp summer beer.
.
I have tried the BIAB technique once before, with an American Pale Ale. I cracked open the first one of those this week:
As you can see, it's a bit hazy with a decent white head. It is less hoppy than most examples, with a smell I can only describe as beery (in the most positive sense one can take that). It has a sweet, bready and fruity taste, and finishes with an ever-so-slightly hoppy and crisp aftertaste.
I love this beer. I predict that it will not last long.
.
So if anyone out there wants to get into all grain brewing but doesn't think they have the chops or space, give Brew in a Bag a try. The freshness you get from using grains instead of extract is worth the additional equipment investment and grains are much cheaper than syrup anyway, so you'll save money in the long run!
.
Happy brewing and drinking!

American Pale Ale

I had to let my American Pale Ale ferment longer than usual, as it was still very cloudy with active yeast at the 2 week mark. But, but Sunday evening it had cleared up and it was time to bottle.

As my fans know, bottling can be a pain. I had not found a good way to add the necessary priming sugar to the bottles for the yeast to eat and carbonate the beer. Adding sugar to each bottle was tedious and imprecise, and led to sticky bottlenecks.

So then I tried CarbTabs, which are premeasured, compressed sugar pills that can be dumped in the bottle. The problem with these was they never dissolved all the way, so there were white bits floating around in the finished product. They didn't taste like anything or register as a texture on the tongue, but they definitely made the beer look like crap.

So, I decided to use my two container system for bottling. I added the priming sugar (1/3 cup of sugar, boiled in 1 cup water and cooled) to the Mr. Beer fermentor, bought some vinyl tubing, and let the beer run from the bucket fermentor, through the tubing, and mix with the priming solution in the Mr. Beer keg. I did not snap a pic, but my mad Photoshop skillz can offer this approximation:



Truly a thing of beauty, yes?

So after the beer was mixed with the priming solution, I sanitized the bottles and filled and capped them. Should be nice and carbonated in 2 weeks, but I usually pop one at 1 week, just to see how things are going.

Tastes out of the fermentor have been promising. The "fresh" taste from doing it all-grain vs. using the extract syrup is very apparent and once it's carbonated and chilled, I think I'll have some great beer on hand.

Stay tuned for a full work-up on an all-grain batch, and reviews of the Pale Ale.

¡Salud!

Lazy, Picture-less Post: Steam thoughts

So I've had a few of my steam beers side-by-side with the real-deal Anchor Steam and it's a mixed bag. My steam is a very good beer, if a little too yeasty, but it doesn't really taste anything like Anchor Steam. Anchor's variety has a very crisp taste, while mine has the aforementioned yeasty and fruity character.

Possible reasons

1. It's too damn hot. Technically, the yeast I bought works best at around 65°F, but I'm sure the daytime temp of my condo in DC hovers close to 80 when I'm not home. This could've led to more fruity esthers and phenols during fermentation.

2. No secondary. In all my brewing adventures, I have only used one vessel for the whole fermentation process. It hasn't been a problem before, but I probably should have decanted the fermenting beer off of the primary yeast cake after about a week. This should lead to cleaner, crisper-tasting beer. Will probably do this with my future batches.

3. The yeast isn't very flocculant. "Flocculant" means that it comes out of suspension and settles at the bottom of the bottle. My previous batches with dry yeast always had a solid layer of yeast on the bottom of the bottle. I used a liquid yeast for this batch, and it will swirl up back into suspension (even when chilled) if you so much as look at it, which leads to lots of yeast in your glass, and lots of gas out your... well, you know.

So, I was successful in making a tasty beer, but failed at cloning an Anchor Steam.

In other brew news, I did my first all-grain batch on Thursday. An American Pale Ale, stay tuned for the results...

Brew Day: Partial Mashing

Apologies for the lateness of this post.

The partial mash went very well. In a couple weeks, I will be drinking my Steam beer.

Recipe:
~3 lbs of Pale/Gold Malt Extract
1/2 lb of Crystal 40 Malted Barley
2 oz of Maltodextrin powder (non-fermentable sugar that adds body but little to no flavor)
1 oz of Perle pellet hops (3/4 oz boiled for 1 hour, 1/4 oz boiled for 10 minutes)
1 pouch California Lager liquid yeast (made into a starter)
Lots and lots of DC tap water. MMMMM-mmmm


The first thing you do on any brew day is boil a bunch of water. You need boiled water to go in the fermentor, but also to do lots of small little things like rinse off things that need to stay sanitized.



While that's boiling, sanitize all equipment that will touch the wort once it's cool. That means the fermentor, thermometer, stirring spoon (maybe), etc.

Take a gallon of your pre-boiled water and cool it off in a water bath in the sink. It doesn't have to get all the way down to yeast-pitching temp, but you don't want to melt your fermentor, either.

And now, the big new step for a partial mash: Steeping your specialty grain.


There are dozens of kinds of grain that are used in brewing. The variety above is called Crystal 40. It is barley malt that has been kilned at higher temperatures, caramelizing some of the sugars. The number indicates how caramelized/dark it is. Crystal malts range from 20 (very light) to 120 (very dark).


We will steep this grain in 160 degree water for a half hour to extract a bunch of color and flavor. The grain sock is used so that it can be easily removed once steeping is complete.


While steeping, it smelled very sweet and bready. I was also very surprised at how quickly the color of the water changed.

After the grain steeped, brew day proceeded as it usually has for my previous extract batches. We add the Gold Malt Extract syrup:


I added the bulk of the hops at the beginning of the hour long boil. This is the "bittering stage." The alpha acids in the hop isomerize in the hot water, and cut a lot of the malty sweetness of the grain and extract.


Then, with 10 minutes left for the boil, I threw in the last 1/4 oz of hops. This is the "flavor and aroma stage." While the bittering hops' acids are cutting the sweetness, all of the aromatic oils are being boiled away. So in order to have some hoppy taste and smell, we add some hops here at the end of the boil.


Once the boil is over, we quickly chill the wort in a water bath in the sink. Then we pour that chilled wort into the fermentor and add our yeast from the start we made on Wednesday. A lot of liquid had evaporated during the boil, so I added some cooled boiled water to get back up the 2.5 gallon mark.

Give the whole thing a good shake to make sure there's plenty of oxygen for the yeast to party with.


And voila! Our Steam beer is fermenting happily in the Mr. Beer keg. It had a nice, thick kreusen on it by Sunday evening, indicating healthy and vigorous fermentation. Bottling on May 2! Stay tuned!

Steam Beer Step 2: Making a starter

Yesterday, I smacked my smak-pak of yeast. If the pack swelled, that was my sign that I had healthy, strapping young yeast to work with. Judge for yourself:


So, now that the yeast pack is definitely viable, we brew up a starter wort. To do this, I boiled 1 cup of extract with 1 quart of water for 10 minutes. I also added a little baking yeast to the boil. These yeast cells are killed in the boil, and dead yeast cells make excellent food for our living (and much more expensive) yeast cells.


After the boil, I cooled the starter wort by placing the covered pot in a pool of cold water in the sink. While that was cooling, I sanitized the large water bottle that would be holding the starter, as well as the outside of the yeast pack and a pair of scissors (can't be too careful when it comes to sanitation).

Then I added the wort and yeast to the bottle. The liquid yeast is a very light tan, sort of like cat formula:


Once it was all together, i gave it a good shake to make sure there was enough dissolved oxygen for the yeast to party with. Then i put the cap on loosely and put a piece of plastic wrap over the top. This is to allow gases to escape, and hopefully keep any bad nasties out.


And there it is, a finished yeast starter. I will let this ferment until brew day on Saturday, when the whole thing will be pitched into the main wort.

Stay tuned for the main event! Beermageddon!

The Setup...

Due to popular demand, I'm going to show you good people our homebrew setup.

The one that started it all...


My Weizenbock is fermenting happily on our kitchen shelf next to some salvaged, pry-off bottles that it will go into this weekend. The two-handled thing is the bottle capper.

And the fermentor that we made ourselves.

A good fermentor only has two requirements: it can hold liquid, and have some method of allowing gases to escape, while not letting any bad nasties in. We used a rubber stopper and airlock setup. The liquid in the airlock is vodka. You want something that won't harbor bacteria.

In order to avoid buying (and having to store) any siphon equipment, I recommend installing a bottling spigot on the fermentor as well. If the bottom of the spigot inlet is about 1/2 inch from the bottom of the bucket, you should be safe from getting any trub (gunk from the bottom) in your bottles. Also, avoid the spring-loaded spigots, as the spring will lose tension over time and you will lose your airtight seal.

I got the bucket and lid from usplastics.com and the stopper, airlock, and spigot from stompthemgrapes.com. All together with shipping, it was about $20. Also, you will need a 1 inch spade drill bit and an electric drill to make the holes in your bucket.
