Batch 168, Guava IPA

Second attempt at this Guava IPA recipe. I made all the changes I thought about from last time:

  • Increased the Munich to 5 lbs
  • Increased the guava to 1.5 lbs
  • Used Magnum instead of Citra for bittering
  • Eliminated the crystal
  • Used London Ale III yeast

Notes

Guava paste didn't dissolve in hot wort, so put it in the blender with some hot wort until it was smooth. Poured it back into the boil kettle through a strainer, only caught some hops and a couple of pea sized pieces of guava paste.


May 11, 2015: I kept waiting for the FG to drop to around 1.015, then I realized the recipe says it should be 1.019, which is where it was last Friday. Transferred to another bucket for secondary, added 1 oz Citra for dry hopping.

Batch 167, Panama Red

We had a small party over the weekend, and the keg of Panama Red blew. Should have brewed a replacement batch some time ago.

This batch has a slight adjustment since I am out of Crystal 60, so I used a little Crystal 120 and a little extra 2-row to substitute.

Some brew day pictures:

The bin holding my 2-row slipped, that's about 20 lbs of grain on the floor.



Hit 154F with no adjustments, nice!



First wort hops, almost at boil



The hops smell delicious

Took this one the next day, fermentation is going well.

Batch 166, Guava IPA

This is a new recipe that I've been wanting to work on. I had a guava IPA in Chicago a few years ago, $18 for a 22 ounce bottle. I had two, they were that good. For this first attempt, I wanted to make sure there was enough malt backbone for the fruity flavors of the Citra hops and the guava, so I used some Munich malt. I also added a little Crystal malt to make sure there was some residual sweetness, which should help promote the guava. Wheat for head retention, of course.

The guava is actually a guava paste I found on Amazon. It's from Brazil, and comes in 1 kg blocks. The Brazilian name is "goiabada", and is actually a popular dessert there. In English speaking countries, it's also known as "guava cheese". The ingredients are just guava and sugar. It's pretty tasty as is. I thought it would be like honey, something to add at the end of the boil, but it didn't actually melt in a couple of quarts of hot wort. I put it in a blender with some hot wort and blended until smooth. I poured it back into the boil kettle through a strainer, but all I got was a few hops and a couple of pea-sized pieces of guava. Having never used guava paste before, this batch is really an experiment to see how it works. Pure guava nectar is almost impossible to find.



This is a 5 gallon batch.

Other notes --

I had meant to use Crystal 60, but I was out, so I used Crystal 10 instead.

Only Citra hops in this. As far as I can tell, that's all that the brewery in Chicago used in theirs. It's a real fruity smelling hop, so it should compliment the guava nicely.

The 158F mash temp is again to retain some residual sweetness. Hopefully, not too sweet.

Actual OG was 1.070.

Notes

Guava paste didn't dissolve in hot wort, so put it in the blender with some hot wort until it was smooth. Poured it back into the boil kettle through a strainer, only caught some hops and a couple of pea sized pieces of guava paste.

Dry hop with 1 oz Citra in secondary.

Updates:
April 10, really violent fermentation! It's not often that I get a blow off with a 6.5 gallon fermenter.

April 11, fermentation has slowed, but is still quite active. I tasted a small sample, it's still somewhat sweet, but the guava and the hops seem to be in a nice balance.

April 20, finally down to 1.016, so kegged it. I think some adjustments are in order:

  • Bump up the Munich. There isn't enough malt backbone. 
  • Bump up the guava. There is some guava flavor, but not quite enough.
  • Replace the 60 minute Citra with Magnum, and increase the amount. It's not quite bitter enough to offset the sweetness.
  • Drop the crystal. I don't think it needs the added sweetness.
  • Maybe go with London Ale III instead of American Ale II? I don't think the fruitiness from the American Ale II is needed, the London Ale yeast is more neutral flavored.
