General Information
Method: All Grain

This beer is dedicated to my dog Bolt who passed away recently. He was my duck hunting partner and will be missed. To quote Neil Young - "we found things to do in stormy weather, long may you run".

Over the past year I've taken the Northern Brewer Tongue Splitter recipe and modified the hop schedule to a single hop variety - Simcoe - my personal favorite hop. I've also tried to imitate Surly brewing Furious a time or two and used Amarillo hops in the process. I've also made the NB Three Hearted Ale which has a higher malt bill than the Tongue Splitter or the Furious.

This beer is a blend of all three. A malt bill similar to the Three Hearted and a blend of the hops that are used in all three. I used fresh hop cones ordered on-line from They smell so good you can taste them!

I design my beers using BeerSmith software. According to the beer style, this one's a bit higher on the IBU's than the style guide but I'm OK with that!


11/29/09 - Day 8 and I've racked this brew into a glass carbouy for a week to let it settle prior to putting into the keg with the dry hops. It smelled good and looks good. Did not taste or measure specific gravity.

12/10/09 - took a sample today. Specific gravity measured out at 1.008. It's got the golden hue I was shooting for and it tastes quite good pre-dry hopping. At this point it seems very well balanced - maybe a bit leaning towards maltyness so the dry hop should round that out nicely. It's not heavy on the tongue and has a nice bitter finish. Based on the flavor of this sample I decided to transfer to keg and dry hop with 1.5 ounce of Simcoe. It is also quite clear and bright for this stage of the game.


12/13/2009 - put in the fridge and applied CO2. It smells so dang good!
