So far, it's been a hot summer and a short summer. And that's to say summer hasn't officially yet begun. As manic as winter had been, summer crept around the Twin Cities like a lurking radioactive monster. From windy to above average hot, that was only after the tornado season began in north Minneapolis.
One can imagine how fun it is to be a siren enthusiast. Oh yes! There is such an internet culture that posts homemade videos of rotating civil defense sirens for those who seek. A huge variety of people across the globe are into it. Truly they make up a fraction of homebrewers' ranks, but I'll say that the first Wednesday of the month or possibly a storm-laden afternoon summons my hobbyist ambitions as first-wort hopping would.
My spare time fascinations led me to envision drinking an IPA with the wailing taste of the iconic yellow-orange Thunderbolt siren. To me, the contrast of bittering & aromatic uses of Simcoe lay one & the same with the ominously beckoning tone of those long-necked, square-horned sirens of the 1950's.
Hey, if terrible weather or nuclear attack sends you to the basement, why not have something bottled in the cellar to match taste & ambient sound when the event arises? I made a recipe late last summer and tweaked it over the course of two more batches (one all-grain & one extract). By the third batch I had what I was looking for: a balanced IPA that matched the color of the deafening object from beside which I wanted to drink. But the tale got seized up, come this summer...
Like a Thunderbolt with a bad air compressor, the supply of Simcoe hadn't weathered the winter well. Though the hop only occupies two additions in the recipe, the valid consensus among fellow brewers remains that no hop can replicate the resiny-piney-grapefruity-ness of Simcoe.
So would I bow to the supply scenario & put away the recipe like so many cities across America have done away with their old supercharged sirens? Would I favor a cheaper recipe that 'does the job' in the same way Thunderbolts have been replaced with new sirens that are little more than giant electronic speakers?
No, my friends... I am rebuilding the recipe with new parts to give this wailing barley beast continued year-round life! Lucky for me, one of the homebrew clubs of which I'm a member hosted a single-hop pale ale tasting comparison this past winter & Simcoe was featured. My notes recalled resinous pine flavor riding a wave of orange flavored bitterness. Grapefruit zest was well-represented too. Other dried fruit flavors were in the Simcoe cocktail too. These club notes were very helpful, much easier to reference than the countless other pales, homebrewed & commercial which featured 'Sims (why else would it have gone scarce?).
The multitude of characteristics suggest the need for a blend of varieties, proportional to the perceived flavor of Simcoe. Treading subjectively into this, I'm estimating the following blend for my initial experiment recipe:
1 oz. Simcoe pellets @ 14% AA =
0.15 oz. Chinook @ 11% AA
3.5 mL Amarillo Hopshot 7.8% AA
0.2 oz. Styrian Goldings @ 5.6% AA
In a definitely unscientific way, I judged the proportions of Sim's various flavors as they might be extracted from other hop varieties that share those characteristics. This experiment leaves out variables such as cohumulone rates, beta acids, and pays only lip service to the non-Sim flavors present in the replacement hops. Truly, it's not perfect. I have only my existing experience using these hops to guide me.
The product of this pursuit will shape the next trial recipe for my beloved pale. All the while, the real subject of comparison remains how my ear tells my mouth how a siren would taste if it were a beer. I'm exposing this experiment for advice & maybe some encouragement; either from homebrew hop blend scientists or possibly others that don't heed a siren's call but bask in it as if it could be held in a glass. Tasting notes to come. Please give input, advice or just plain banter!

Tasting notes for my Thunderbolt Pale Ale, using a blend of hops to approximate the profile of Simcoe: 7/11: 1.5 weeks in primary - 1.009 gravity. Hop bitterness is nearly the same as the original recipe. Centennial & Mt. Hood flavor totally unabridged. Hop aroma seems to be leaning toward pine, though at this early in fermentation it's not all that different from the aroma profile of the original recipe. Secondary transfer 7/12. 7/17: 1 oz. Columbus added to secondary. Estimated 7.7% ABV. 7/22: Dry hopping & secondary has mellowed the piney characteristic to a lull. Simcoe flavor is well-replicated, if only very slightly muted by the substitution blend. Really, there's little difference from earlier Thunderbolt brews.
7/29: First pint from the carbonated keg (3.0 vols CO2). Cleanly bitter, big malt character has a clean caramel taste, finish is balanced by lots of orange-like citrus hop flavor. Resinous hop character plays second fiddle to the orange/grapefruit/misc. old fruit aromas. Real Simcoe would have given more resin aroma, but the final beer is hardly deficient in that regard. Good yellow-orange color with a respectable white head. The finish leaves a pine flavor, yielding to citrus-zesty coating on the back of the mouth. It seems the Simcoe substitute blend did well for the T-bolt. I give thumbs up to the blend. Brew on!
