Hop Mothra IPA by Jim Nielsen (Malt Extract Kit)

Hop Mothra IPA by Jim Nielsen (Malt Extract Kit)

Please select from the following option(s) to see pricing and availability.

If you have a monstrous craving for intense hop flavor, you’ll need a beast of equal proportion to do battle. Enter Hop Mothra! This liquid kaiju isn’t interested in saving (or destroying) Tokyo. Her only motive is to slake your thirst and leave you yearning for more – so much so that you’d swim to Infant Island for another taste. With a nice malt backbone (err thorax?) this beast will soar over your tongue and, with a flap of her wings, send a hurricane of hop flavor to assault your taste buds.

Jim Nielsen’s Hop Mothra IPA uses 10 lbs of Ultralight Malt Extract, 1 pound of Light DME, and a trio of crystal malts that give this beer a beautiful pale to medium amber color. Perle, Cascade, and Liberty hops lend a spicy aroma with flavors of grape fruit and citrus.

Jim began home brewing in 1994, but it wasn’t until the Great American Beer Festival of ‘98 that he came across a beer that would alter the course of his hobby. Grant’s Brewing Company made a batch of beer especially for the festival – Hopzilla! This beer made such an impression on Jim that he decided to take his passion for home brewing to the next level, and he began his search for a brew system that would allow him to do everything the pros can do. He helped MoreBeer! develop one of our first digitally controlled brew sculptures, and not long after he had brewed his own version of Hopzilla that he (unsurprisingly) enjoyed more than the original – HOP MOTHRA! Raise a glass to Jim, and give thanks for this monster of an IPA.

Please Note: In order to better serve our customers, we are now offering our extract recipe kits with either Liquid Malt Extract (LME) or Dried Malt Extract (DME). The majority of our DME kits were converted from the LME version, which is why you may notice slight variances in the extract names and quantities on your recipe sheet. You may also find that your Specific Gravity and ABV% are slightly higher if you choose DME. Whether LME or DME, add all extracts provided according to the recipe sheet.

Not my favorite
I brewed this once. I don't really have any desire to brew it again. There isn't anything bad about it but it doesn't fit into the category of beers that I drink.

Great Beer
This is only my second brew. I followed the recipe and then dry hopped with four ounces of whole Williamette hops for about two weeks. I am absolutely in love with this beer. I would like to do it 3, 4, 500 more times and experiment with it to dial it in some more to my tastes. Great recipe; I am a self diagnosed hop head and this beer, while slightly lacking in bitterness for my tastes, kicks butt. I will be brewing this one again soon.
