Brew Day – My Mosaic – 12/17/2018

Founder’s makes a really good Mosaic centered IPA (called Mosaic Promise). Makes me really appreciate the taste and aroma of the Mosaic hop, so I wanted to design a beer around it. Not quite a SMaSH beer (since the grain bill will have some speciality in it), but kind of close. I learned from my SMaSH experiments that either a touch of caramel 20 or caramel 40 is a nice addition to an IPA.

Going to call this creating “My Mosaic.” If you want to understand why, just sing “My Mosaic” instead of “My Sharona.”

Okay – I’ll stop now.

The recipe:

I’ll admit, I’m going a little nuts on the dry hopping. I’m doing a full ounce of Mosaic for a 1.5 gallon batch! That is crazy. Ideally, I’d like to hone this recipe and make it part of my regular rotation, so I figured I’d go to an EXTREME fence post, and see if that big of a dry addition will make it undrinkable. If it does – oh well, I’ll cut it in half next time. If it doesn’t, I’ll add more next time. I can’t imagine that I can do too much more though. I guess we’ll see.

The Steps:

  • 75 minute mash
  • 60 minute boil
  • Hops @ 60/10, and dry after primary is done
  • Yeast nutrient and fining agent at 10 minutes
  • 1 pack of rehydrated S-05

The Numbers:

  • Pre boil volume target: 2.12 gallon
    • nailed it
  • Pre boil gravity target: 1.047
    • exceeded @ 1.052
  • Post boil volume target: 1.72 gallon (1.65 into the fermenter)
    • had to top off with cold water
  • Post boil gravity (OG) target: 1.060
    • exceeded @ 1.072
  • Final gravity target: 1.011
    • nailed it
  • Est ABV (actual): 7.9% (yowza!) – very high end for this style

Misc Notes:

  • BIAB stovetop (small batch)
  • No sparge method
  • Everything pretty much went as planned!

Fermentation Notes:

  • Brought a space heater in to the basement to help fermentation area stay around 70 degrees
  • 12/18 – FINALLY bubbling
  • 12/24 – gravity reading at 1.011 – terminal gravity reached
  • 12/24 – added 1.38oz of mosaic hops (dry hop add)
    • Note – the recipe I wrote called for only 1 oz of dry hops. I had .38 oz extra in the fridge, so I figured – what the hell??? Throw it in!

Tasting Notes:

  • 12/24 – slightly bitter – will definitely benefit from the dry hopping!
  • 12/29 – drew a couple samples for my buddies – AMAZING. Rave reviews. The aroma and hoppiness were very pleasant. Looks like I could have added more!
  • 12/30 – bottled – ready to drink in a week or two
