Tasting Notes
Great! Kirin-like!
Fellow brewers,

I have brewed a lot of mediocre beers lately so I am glad that I can report finally a full success again. This one was intended to be a type of Kirin Ichiban clone, with a little bit less abv. If you want it to be true Kirin abv, just increase the pilsner malt amount by about 15%.

When I have a sip, it reminds me of kirin and it is only one week in the bottle by the time I am writing this. The head retention is also already great, I am in love with this one here.

The Yeast is really clean at room temperature (around 20C), the beer tastes like a lager so don't be afraid to brew this, even if you have no temp controll. It can obviously be refined by controlling the temperature, but it still is a very good beer without it. I doubt anybody would notice that it is a warm fermented lager if unaware of the fermentation temperature.

I somehow miscalculated my hops a bit, so my version is more like a pilsner with more ibus but nevertheless a very good beer. Actually, now that I think about it, it tastes like Sabro. The malt shines, the hops also, job done!
Btw. I did not use any kettle finings and I intentionally did not remove ANY trub or floating stuff during the boil. EVERYTHING (except the hops) went into the fermenter. The result is the fastest clearing beer i have ever had. I have clear beer in my glass one week after bottling. Hard to beat!

If you want a clean and easy brew that is also a crowd pleaser, this is the one.

Cheers!

PS: Yes, the step mash is necessary. Because I am German and I have to do a Hochkurz Mash, otherwise the Beer gods might punish me for being naughty. I do not want that and you also do not want that.

Boil Time: 60 min

STATS:
Original Gravity: 1.040

Acidulated Malt (2%) (OPTIONAL for treating water alkalinity)

HOPS:

YEAST:
Lallemand - Diamond Lager Yeast
Starter: Yes
3g dry yeast in a 2l starter, stepped up once. Starter OG 1.03.
Form: Dry
Attenuation (custom): 77%

It would be fine to shorten the steps by 5 mintues I guess.

Looks like a very easy-drinking session beer. Barke Pils should give it a little biscuity flavor, and the Carafoam some decent head retention. A nice lawnmower beer.

Exactly! Somehow the Barke is really good at replicating this Kirin malt taste.
 
Would love to know how it compares. Usually when I do this I realize I didn't get it as close as I expected (Negra Modelo, Fullers ESB, Anchor Steam...) - I hope you have better luck!
My guess is that the hops were labelled falsely. The beer I got tastes like 30 or 35 ibus instead of the calculated 20. So that's already far off from the original but I should be able to judge how close the rest of the taste is to the original. And I'm a bit afraid that what you've experienced will be what I'm going to experience as well :D.
 
Taste off!

First the visuals:

Mine is more pale and has slightly better foam. I've waited one minute to see what happens to the foam afterwards, see last pic. Btw. both beers are actually clear. The glasses are a bit misty.

Taste wise, it's very interesting. Malt wise, it's like the colour difference suggests. The Kirin has more malt character but same perceived sweetness. It has zero sulphur, my version has a little bit. There's a maltiness below the little bitterness that is missing in my version. I might experiment with 10 to 20 percent Munich or Vienna to get there.

But the big surprise, the bitterness is spot on. It's exactly the same in both beers. Wow, I'm bad at guessing bitterness.

Overall we have to keep in mind that Kirin has about 1/5 more malt and abv, compared to my beer which obviously intensifies all the flavours.

The verdict: I brewed a great beer but malt-wise it's a bit off compared to the original. 20-30% Vienna or 10-20% Munich might help here.

And there's something else going on with Kirin.... I don't know. It's a bit like an acidic almost fruity flavour/smell but not an ester. I bet it's from Sauergut. I know this from some German Helles. I might have to try making Sauergut... Maybe that's what people call grapenut flavour?

Next time!

Cheers!

Have to drink two beers now! :)

Well alright then. Guess I'll ignore all the "clone" recipes that use flaked rice, rice syrup, or rice solids.
You are required by law to list all the ingridients on the label if you sell stuff in Germany. There is only barley malt listed. People think it is Asian, so it has to have rice. It is a little bit stupid to think that way tbh.

People also believe you should use smoked peat when making Scottish beers as well. Sometimes stereotypes and romantic myths invade peoples notions.
 
Ichiban (or No. 1) is all malt, though I wouldn't be surprised if other brands in Japan use rice. Interestingly, a decade or so ago I was in Japan and my host family thought that I, as a former farm boy, might like to see a grain elevator. Interesting tour, and I found that their processing revolved around two seasons. First was the rice harvest, after which the fields were drained, dried and planted to malting barley. At the time there was no rice in the facility, but lots of bulk bags (1 ton IIRC) filled with barley contracted to Kirin.

I'd love to see that too!
 
Did the sulfur go away with time? That's probably my #1 thing I don't like about lagers so I'm always interested if one is made without that characteristic.

Not really. But it wasn't strong to begin with. Maybe you can omit it with a bit of yeast nutrient. Or you just choose another yeast.
 
It is on my list.

This is my boosted version that is updated using 20% Munich (I only have Barke).... going to 1.049 OG on a 6.5gallon (fermenter) batch

You got a higher OG, so you might want to up the Ibus a bit... like 25 ibus instead of 21. Still 21 should work for this type of beer.

The longer boil will also accentuate malt flavours, which is a good thing.

Good catch. I will up the IBUs. Thanks for the input. I will post when I brew it. Got a few different beers ahead of it.
