For your fermentation, using WLP001 (or the Wyeast/Safale equivalent) you want to hold it at about 64-66F for 2-3 days, then allow the temperature to rise freely up to about 70-72F, then keep it there until you hit FG.

As others have said, drop your mash temp down to the 148-152F range. Your FG at 1.017 is far too high for the style and is undoubtedly due to your high mash temperature. Mash around 150-152F and you should finish at 1.010 which is about right for an IPA.

WRT your grain bill, I'd keep it about the same. 1 or 2 pounds of either Munich or Vienna will add some good malty flavor to an IPA but won't make it sweet.

Also, unless you are using something like a corny keg for your secondary, skip the racking to secondary to dry hop. You are just *begging* to oxidize your beer during the transfer, and you're also probably going to skunk it if you rack into a clear carboy and it gets any sunlight on it. It sounds like you have a temperature controlled fermenter, so cold crash your fermenter then dry hop in your serving keg. Put your hops in a nice fine bag, suspend them in the cold beer for 3-4 days, remove the bag and serve!

Update...

In an attempt to remedy the diacetyl issue, I am going to let the keg sit for a few days at room temperature. Maybe the yeast can do a bit more clean up if the temp gets to 70 or so.

I also tossed a few ounces of cascades into a sanitized hop sock and added it to the keg to see if I can squeeze in some more hop aroma (it is lacking for sure). WE WILL SEE!!


Going to be brewing a German pilsner this weekend. Stoked!

More updates!

My attempt to remedy the off flavors with the IPA mentioned above were unsuccessful. I ended up dumping over half the keg...

The German pilsner I brewed turned out excellent -- very clean and crisp!

Just brewed a Citra session IPA and I think I have corrected my problems with off flavors.

Several suggestions given to me on this thread were helpful. The first, was mash temp.. I lowered my mash temp to around 150-152, which I know helped to reduce the "sweetness" I was perceiving when mashing at higher temps. The second suggestion mentioned here that helped was regarding the grain bill..

Citra Session IPA Grain Bill:

9.5 lb 2-row pale malt
0.3 lb Munich malt
0.5 lb Crystal 60 L

On this IPA I made sure that the specialty malts were no more than 8% of the grist, which also helped to reduce the sweetness.

The third, and one of the most important factors that helped to reduce off/sweet flavors in my IPA was increasing my primary fermentation time. I made a 1.2 L starter, aerated the wort well, and used yeast nutrient. Within 12 hrs of pitching I had a very active and vigorous fermentation. After 7 days the fermentation died down and the final gravity was close... BUT! I left it in the primary for a full 14 days before racking to dry hop. With my previous IPAs I was racking to the secondary for dry hopping once I had reached my final OG in the primary, which was usually around 6-7 days -- not enough time for the yeast to clean up! I thought that so many yeast cells would go along with the beer to the secondary that they would still be able to do their cleanup, but I guess this was not the case... I let my pilsner sit in primary for almost 4 weeks and I think this helped a great deal with making the beer taste clean (which it did!).

Furthermore, dry hopping in the secondary AFTER primary fermentation is finished helped this Citra IPA to obtain an intense hop aroma - much more so than dry hopping in the primary. HOORAY BEER!!

14 days is good. I don't even bother raising temp. Just stay at 65 for almost any yeast (including secondary and dry hop).

I haven't had good luck dry hopping cascades yet. Seems to have a sweet melon taste. I would try using something like Galaxy or Mosiac next time instead of Cascade.

Glad you got it sorted out.
