It took me a little longer to get around to reviewing this
beer then I would have liked but I think the extra time actually helped it.
This might seem counterintuitive for an IPA, but I think the flavors and aromas
mellowed out and became more distinctive rather than muddled together. Part of
the reason for the delay I was because I had problems getting the keg to
carbonate. I’m not sure what the reason for this was, but I finally used the
old shake method to infuse CO2.
The last time I brewed this beer it did not come out the way
I would have liked. It developed a harsh astringent bitterness and was a weird
murky brown color. I placed the blame on mash pH. This caused me to force
myself to learn about mash chemistry, which I think has overall improved my
brewing. I was able to adjust my pH for this beer, but I don’t think I got it
low enough. Lowering my pH did help with the color of the beer and I feel it
also helped to remove the astringent hop finish (the other problem could have
come from poor hop extract). The issue I had this time around came from my
yeast not fully attenuating. I don’t think I made a big enough starter after
going from the can and I think when I stepped up my starter it was too old.
That coupled with an inability to oxygenate didn’t help things for the yeast in
a stressful environment.
Never the less I’m much happier with this batch, but feel it
could still use some tweaking.
Appearance: It pours a hazy orange-yellow with a fluffy off
white head with crazy good retention. The head never really fades from a
centimeter thick lacing and clings to the side of the glass. I wouldn’t mind
clearing it up a little bit, but really I would have to filter in order to do
that. Conan yeast is a notoriously bad flocculater and chill haze from all of
the dry hopping isn’t helping anything.
Aroma: Dank hops up front with peach notes peeking through.
As it warms up some more citrus aromas come up but it’s still pretty dank. I’m
thinking next time I will reduce the amount of Columbus hops and maybe increase
the Amarillo hops. I think I will also cut the dry hopping in half. I usually
notice the best aroma after the first hopping but then the aroma becomes mixed
after the second addition. I was at first disappointed by aroma because it didn’t
remind me of Heady, but the more I drank the more I realized that it was
similar to Alpine Purehoppiness, which I can’t really complain about.
Flavor: Due to the under attenuation of the yeast there is
some residual sweetness that I’m not too fond of but it’s not a cloying
sweetness. The flavor is bitterness up front with piney notes and some orange
flavor blended and some caramel notes. When I was initially drinking the beer I
thought it was too sweet, but the more I drank I started to feel like it was
actually fruity hop flavor.
Mouthfeel: Medium carbonation and a full body with a
lingering bitter finish. I would have preferred for the beer to be dryer and
maybe for the bitterness to be a touch softer. I might dial back the extract
some next time around.
Overall: I think one of the things that I’m going to try to
do next time for sure is to lower the pH a little bit more. I took a reading of
Sierra Nevada Celebration Ale and it came in at 4.44 which is about 0.2 lower
then my beer. I added a few drops of lactic acid to a glass and felt like it
cleaned it up a bit and brightened up the aroma a little. I think the extra stage
of dry hopping also caused the reverse affect then what I was looking for so I
think next time I’ll cut that addition out or I’ll split the first dry hop into
two additions for better extraction. I’m sure getting full attenuation will
probably help as well.
Interesting comparison of the final pH. I wonder how direct of an impact kettle pH has on final pH- I am guessing its not as simple as lowering the mash pH by 0.2 and lowering the resultant pH by the same amount. It might be an interesting pre- keg/ bottling tool to measure and tweak the post-ferment pH directly as you mentioned. I don't think I have heard of anyone doing that.
ReplyDeleteTo your point on sweetness- perhaps you could switch to a less sweet base malt, say some combo of pils and 2-row brewers instead of Perle? All that carapils is probably also killing your attenuation.

I've used a combination base malt before and it does provide a crisper finish. The last time I brewed this beer it finished at 1.012 so it wasn't sweet. I think the sweetness came from the under attenuation. I figured the sugar would help since its only at 6% carapils. Good thing I can always brew it again!
DeleteI don't normally take a boil pH reading but I do know that it should drop anywhere from .1 to .3 over the boil depending on the length and starting pH. I should probably start to check it. Most of the pH drop comes from the yeast. I haven't heard of anyone doing that either, but you'd have to be careful because too much and you can definitely taste the lactic acid.
