Session Beer Brewing

Yeah I know, Light Lagers are the favorite target of beer snobs. The truth is, they could be considered the most popular session beers in the world. I'm not opposed to a nice light refreshing Lager every once in a while so I figured I'd give it a shot and try and brew one.

Technically speaking there's really no reason to homebrew a light lager except for the challenge. They're readily available & you can literally buy them cheaper than you can homebrew them.

For the first attempt, I wanted to keep it as close to the BJCP guidelines as possible. I went with the traditional 6-Row malt instead of the much more popular 2-Row variety for authenticity. Taste-wise they're pretty similar. A lot of people will describe the flavor of 6-Row as having a more pronounced "grain" flavor in comparison to 2-Row. This seems to be a pretty fair description from my experience. Also the extra enzymes in the 6-Row will help convert the starches in the corn, which does not contain any enzymes. I usually use rice in my lagers instead because I like the neutral flavor it gives to the beer but again corn is more traditional. 'Murica.

As with all session beers, the generally low alcohol/malt/hop flavor will allow any flaw to come out very easily. It's even more true for light lagers. Drinkability is also a key component of the style and the low flavors mixed with a light body make for a drink you can, well drink a lot of. You want the beer to finish dry but not so dry it becomes overly thin. I chose to use my favorite Lager yeast, the German Bock strain which attenuates well but still manages to leave behind the perception of a malty finish somehow.

Light American Lager (6 Gallons, ~80% Eff, Tinseth)

OG: 1.038
IBU: 10
ABV: 3.8%
SRM: 3

7 lbs - Domestic 6-Row
2 lbs - Briess Flaked Maize
1.5 oz. - Rice Hulls (added to the last 15 minutes of the mash)
.5 oz - Czech Saaz (Whole Leaf) 4.2% @ First Wort Hop
.25 oz - Czech Saaz (Whole Leaf) 4.2% @ 30 Min

Yeast: 2 packs WLP833 German Bock (2 liter starter, no stir plate)

Mashed 60 min @ 151, 1.5 qt/lb
Fermented for one month at 50 degrees.
Stored for two months at 42 degrees.

Look - Light yellow/straw colored, clear
Aroma - Sweet malt, grains, corn, light earthy hops
Mouthfeel - Light-medium, finishes dry but with a nice malt presence, slight carbonic bite
Taste - Sweet grains with a hint of corn, minimal spicy hop flavor lingers in the finish

Notes:
Overall this is a highly drinkable beer & I'm really happy with how it came out. I was surprised how much it tasted like your run of the mill light lager, except with more flavor. The only criticism I have is that it probably has too much hop & malt flavor. I underestimated how little the malt flavor would mask the hop flavor. I'm used to brewing all malt beers for the most part. 6-Row isn't necessarily a flavorless malt but when you combine it with such a high percentage of corn, the amount of malt you taste drops off pretty substantially.

This of course is the whole point of a light lager and contributes to its drinkability, so just keep it in mind. I would definitely drop the second hop addition and if I was to enter this into a competition I would probably enter it as a Standard American Lager, for fear of it being too flavorful, as weird as that sounds.

After moving from a house with a basement & a brewstand I had to make some changes in order to be able to brew the same amount in a 1 bedroom ~650 sq. ft. apartment. In full disclosure it helps to be a bachelor haha.

Brewing
Instead of the two natural gas Blichman burners I had on my previous system I only have my stove as my single heat source now. It has 4 burners but its small stove & as you can see from the pictures below, the boil kettle takes up all four burners. The stove does an OK job of bringing 12 gallons of wort to a boil. Not nearly as fast as the natural gas burners but not too terrible either. Maybe 45 min on average.

It's illegal to have a propane burner where I live & I don't have an accessible roof for a charcoal burner (which would be less than optimal anyway). I thought about an induction heater but ultimately decided against it because my HLT wasn't really magnetic enough & I was worried about the weight possibly damaging the element.

So in the end I decided to convert my HLT into an Electric HLT with a hot water heater element. There are people out there who brew entirely with electric water heaters and report good results. Lucky for me, there are a ton of really good tutorials on the internet for how to properly install a hot water heater element on an HLT. I ended up using these instructions which I would recommend The instructions were clear & all the parts meticulously listed. I'm not the most mechanically inclined but I can follow directions haha.

I went with a 120v heating element because I don't have a 220v outlet in my apartment. Also, I'm just using it to heat water so it doesn't have to be strong enough to boil or anything like that. The single heating element works just as well as my stove. It heats up the strike water to ~170 F in 45 minutes. In the future if I ever have the time I might add another heating element & insulation to the outside of the HLT, to speed it up.

Having an Electric Kettle helps to speed up the brewing process by allowing me to heat the sparge water while I'm mashing without having to move it off the stove to make room for the boil kettle. With only the stove as the heat source you have to sparge into buckets and then transfer that to the boil kettle after the HLT is empty & light enough to move.

Storage

The free standing shelf is from Ikea & the best part is you can move the shelves anywhere which makes it easy to fit large bulky things like the mash tun etc.

Brew Tower
It's a More Beer stainless pump & chiller stand. I also added my RV water filter to it to make things easier for me.

Fermenting
Fermentation temperature control is one of the most important factors for consistent & high quality beer. I have a 7 cu ft GE chest freezer which holds two 6 gallon Better Bottles perfectly. There's a little cut out in my living room and it fits nicely in there as you can see from the pictures.
