Last year was the first time since having the freezer that I didn't brew any lagers. This happened for two reasons: 1) I was kind of on a big hoppy kick and kept brewing APAs, IPAs, etc., and 2) my fermentation chamber had become a keezer; with 3-4 taps flowing at a time, there just wasn't enough room for a carboy, let alone two. This year, however, I figured that I could take the time to brew at least one or two; by cleverly using the back, closed-off room of my garage for fermentation (acting as my beer cellar, it's kept at a perfect 48-50 F thanks to a simple digital thermostat), and the garage itself for lagering (it's typically 2-4 F during January and February), I thought I could make it work.
So, in early January I brewed a Festbier (think paler, more-bitter Oktoberfest) using a private collection strain from Wyeast, Munich Lager II. I've used this strain before in a Vienna Lager and a Schwarzbier, and was quite happy with it... good malt character, decent attenuation, less diacetyl-producing. The Festbier turned out pretty decent, and - as usual for my method to brewing lagers - I kept lots of slurry to re-use for another beer. I had full intentions of brewing a bigger beer, like a Bock or Doppelbock, but as usual, all those hops in the freezer were calling to me...
While India Pale Lager is not a defined "style" of beer (at least, it isn't in the BJCP), that - as usual - doesn't keep plenty of commercial breweries from brewing it. I don't think I have to get too technical here: an IPL is basically an American IPA fermented with a Lager yeast strain. I believe the idea is that since Lager strains generally give a very clean beer (if brewed properly), an IPL should bring the hops (and supporting malt) even more forward than when used in an IPA (even one featuring a generally-neutral yeast strain, such as US-05). I can't really comment on whether this is true; I've never brewed an IPL, and I haven't tried many of them either. The standout for me is one that is definitely impressive to have been brewed well, TrIPL, a 10% monster with CTZ, Chinook and Citra from Jack's Abby, probably one of the best Lager breweries in North America.
Well, I decided to give it a go, if only to see if there was really a difference between a heavily-hopped Lager vs. a heavily-hopped Ale. When putting together the recipe, I didn't want a beer that was too dark, of course, but maybe something that wasn't Light Lager yellow, either. I was originally going to go with all-Pilsner malt for the base, as I would with a lot of pale Lagers, but after a bit of reading online, I decided to add some 2-row in. I made up the rest with some Munich, Wheat malt, and Melanoiden, trying to give the beer a bit of body and provide some breadiness. A bit of Acid malt, as usual, and that was that. I mashed fairly low, at 150 F; I wanted a fairly-dry beer, and with the attenuation of the Munich Lager II not being super-high, I hoped this would give me a good balance of enough-body with not-too-sweet.
I went with three hop varieties, one that I've used plenty of times, one I've used once and really enjoyed, and one that I've never brewed with before:
- Cascade - We've all used Cascade, and it often gets forgotten in the mad rush of new, hot hops out there... and it's a shame. Sure, it may not be as potent as Galaxy, Azacca, Citra, Mosaic, etc., but its citrus and grapefruit characteristics can be truly wonderful in a hoppy beer, and I've been trying to use it more often lately.
- Comet - I think this one has been around for awhile, but I hadn't brewed with it since my 2015 Meek Celebration (Christmas giveaway beer), and I really liked it in that beer. Described by the Bear Flavored hop guide as "intense wild American grapefruit/citrus character, extremely dank"; it doesn't disappoint. So obviously, I'm looking for grapefruit in this beer.
- Vic Secret - A new (~2013) Australian variety, this hop has been doing well - I see it popping up in a lot of beers lately, and I tried a single-hop beer from Fredericton's TrailWay awhile back that was quite good. Described as exhibiting flavours of passionfruit, pineapple and some light herbs and resin, I thought it would work nicely with the Cascade and Comet.
I mixed it up a bit as per the hopping schedule below, with an ounce or slightly more (when using up stock) of all three in a single dry-hop. But that raised the question: what is the best way to dry-hop an IPL? Do you lager the beer first, and then dry-hop? Or is the lagering period also the dry-hop period? Problem is, even light lagers are lagered for longer than your typical dry-hopping time (which is often no longer than 5-7 days, or even shorter). I looked into it some, and turns out that - surprise! - there are a lot of different opinions on the "best" way to dry-hop a lagered beer. So, I chose the following method: brew the beer, ferment cool as expected, raise temp for a short diacetyl rest, bring back down to ~50 F again, then after a couple weeks total, rack to a keg and lager the beer. After several weeks, throw the dry hops in that keg, move the keg inside to a warmer temperature for 5 days, then transfer the beer from that dry-hop keg into the serving keg, chill and carb. Make sense?
The brew day was fine, if a little longer than usual - with a 90-minute boil, a hop steep of 15 minutes, and having to chill to 50 F or lower, it definitely stretched out compared to an Ale brew. Fermentation was going about 24-36 hours after pitching, and in true Lager fashion for me, never got crazy... the airlock bubbling every 2 seconds for several days is what I'm used to for Lagers. After about 5 days the bubbling started slowing down, so I moved the fermentor inside for a 2-day diacetyl rest in the mid-60s F, then moved it back to 50 F ambient. After two weeks total, I racked the beer to my "dry-hop" keg and left it in the garage to lager... not exactly the most regulated way to do so, but my garage was holding at about 40 F or so, consistently, so it would have to do. Two weeks later I threw in the dry-hops, moved the keg inside for 5 days, and then transferred via CO2 to a purged serving keg, and started carbing.
And how did it turn out? I've got to say, I quite enjoy this beer. Really smooth and creamy, it's got a fruity, candy-like sweetness to it that in no way overshadows the citrusy, fruity, slightly-herbal flavours from the hops. The malt also complements the hops well, but be very clear, this is a hop-forward beer. It just seems a little less dry than a lot of hoppy ales I've brewed, but it's still juicy. That's the best way I can think to explain it. I'm sure a different Lager yeast with a bit higher attenuation would result in a drier beer, but I like how this tastes, and I'm a big fan of the mouthfeel.
This is something I'll definitely try again, although now it's probably going to have to wait until next winter. Lots of room for experimentation here - with many Lager yeast strains to play with, not to mention all those wonderful, wonderful hop varieties, this is a style I look forward to revisiting again. In the meantime, I need to track down some more commercial examples...

Appearance: Pours with a moderate-large size white head that shows good retention, eventually fading to 1/2-finger. Body is a deep-golden colour, with very good clarity.
Aroma: Pleasant bready malt character, with a strong hop presence that is fruity and tropical, for the most part. Clean, no diacetyl, no sulfur.
Taste: Lots of hops, tropical, citrusy, with a bit of an herbal-like quality that two fellow beer geeks picked out. Backed by the malt sufficiently, but definitely a hoppy beer. Finishes crisp and fairly dry, smooth and easy-drinking.
Mouthfeel: Medium-bodied, moderate carbonation. Very smooth and creamy.
Overall: Very enjoyable; I haven't had a lot of IPLs but this is one of the better ones I've had for awhile. Definitely a recipe to play around with; changing hop varieties and yeast strains really opens the possibilities.
Hey there, two years later I'm trying this recipe changing some supplies (because I live in the other edge of the world and there aren't some hops and malts here). Can I ask you a question? What do you mean "In primary" when dry hopping?
