| The Cascade Wet Hop Harvest Ale |
Now with the brewing and serving of O Hike Ale over with, I am excited to get into brewing more outside of the 1056 American Ale brewing. Brewing the test batch of the O Hike, the Terrapin Rye Pale Ale, the American Wheat Ale, the O Hike final batch, and the Wet Hopped IPA has allowed me to brew a lot with the very typical and very common 1056 strain a lot in the last few weeks. It's a grain strain to use; very resilient to any mistakes you make as a brewer and often produces a great beer, but I'd like to produce beers with some additional variety for the fall and winter months.
The Trappist High Gravity 3787 strain from Wyeast should get me out of my American Ale yeast funk. I've wanted to brew either a Belgian Tripel, Belgian Golden Strong, Belgian Quad, and/or a Belgian Strong Dark for some time now, and I think this yeast will make for a fantastic Belgian strong ale if I use it correctly. Since I have a few dark strong ales available at the moment, I thought that a Tripel or Golden Strong would make the most sense, possibly a brew for mid-winter. Jamil Zainascheff had yet another seemingly straightforward yet quality recipe for the Tripel style, so I chose to go with it.

Yeast
Propagated 3787 Trappist High Gravity propagator pack three times to produce ~150 mL of yeast. Pitched ~110 mL of thick yeast slurry, pitched remaining yeast from starter diluted with water. Aimed and hit to pitch between 112 mL and 150 mL of yeast. 112 mL suggested pitching rate for 1.060 OG (when fermentation began), 150 mL suggested rate for 1.080 OG (after additions of cane sugar).

Ca: 85 Mg: 2 SO4: 19 Na: 15 Cl: 17 HCO3: 164
(targeted Chimay water profile, carbonates lower than desired)
1 Whirlfloc tablet (5 min) 1/2 tsp yeast nutrient (5 min)
Mash Schedule:
Single Infusion 60 min (roughly 148-149 F, dropping at mash progressed)
10 min mashout at 170 F
1 g NaHCO3, 0.5 g CaSO4, 0.5 g CaCl2, 4.5 g CaCO3,
6.5 mL Lactic Acid (60 min), ~5.4 pH (30 min),
added additional 2.5 mL Lactic Acid (30 min, ~5.4 pH (5 min)
Yet another seemingly hellish brewday, but I'll have to see how the beer turns out to make the final judgement. My mill continues to create issues. I think at this point I will have to abandon wet milling altogether, if not for a while and begin wetting the grain to a lesser extent. The mill rollers, even though I am taking much better care of them now, still struggle towards the end of milling. The drill is unable to continue to mill once the rollers have turned the grains to mush. This can't be a good thing for mashing and could be resulting in tannin extraction, although I think overall wet milling has likely decreased tannin extraction. I'm not sure if the failure is the drill being weak, the grain being too wet, or this mill not being capable of handling wet grains. I'll have to go back to dry milling, and at some point, possibly begin experimenting with wetting the grains to a lesser extent.
My mash numbers seemed to be a bit off, and I continue to be a bit confused over what exactly I should be measuring when it comes to mash pH and mash temperature. I chose to measure temperature on top of the grain bed and below as I had on the previous brew. My measured temp I went with was the one I measured below the level of the grain bed (~148 F), but I have little way of knowing what temperature is most significant. I would like to get a thermowell and thermometer and install both in my mashtun, but this may be an upgrade for the future. In the meantime I'll have to monitor some area of the mashtun consistently to get an idea of the final that will be produced. pH was especially confusing since I initially hit a pH of 5.4, then added an additional 2.5 mL of Lactic Acid and still hit the 5.4 mash pH. This is a beer that is more likely to benefit from a "softer" texture, and so I am ok with a higher mash pH, but I am a bit confused as to how adding the additional acid resulted in no pH change. I think this is another area where investing in equipment to measure weight in grams, volume in mL, and a legitimate pH meter may come in handy in the future.
My issue with my mill would not ultimately be my only issue. I again had a stuck mash (2nd time in the last three brews), however this stuck mash was most likely due to me not attaching my outlet tubing in the mashtun to the false bottom with a hose clamp. Since first brewing with this mashtun assembly from Northern Brewer, I haven't been using the hose clamp that clamps the outlet tubing to the false bottom since I had one particular brew where I had a stuck mash due to the outlet tubing being twisted, crimping, and making it impossible for any wort to drain from the mash. In the future, I'll either have to either clamp this tube as I should be doing and make sure not to twist the outlet tubing, or clamp tubing that is unlikely to crimp due to the high temperatures silicone tubing experiences in the mash. This issue, as with the mill, are most likely only frustrations on brew day, and are not likely to result in a lower quality final beer, but the mash issue most likely did result in my lower efficiency (67%). It would make things more enjoyable to avoid issues like this altogether in future brews.
For the first time, I had a blockage in the flow of wort into the fermenter after chilling. I've never had this happen, and after this particular brewday, it didn't really surprise me. With such a small addition of hops, I had not idea how the strainer could be blocked. After using a sanitized ruler to strip away some of the hops from the strainer, I was finally able to collect a little over 5.5 gallons. It looked like it was only hops that clogged the filter, not protein. I'm thinking this is most likely due to not allowing enough time for the trub to settle to the bottom before draining the boil kettle. Again, I'll have to see how the strainer works during the next couple brews, although I've never had an issue with it before so I'm confident it won't be a reoccurring problem.
One issue that I think may be more significant in the resultant beer is the fact that I think I was given CaraAroma malt instead of Aromatic malt at my local homebrew store. I guy filling in for the homebrew store owner I think must have seen "aroma" when I asked for "aromatic" and thought it was the same type of malt. The CaraAroma is much much darker and will likely result in a different flavor, similar to the flavors in a Belgian Dubbel or Belgian Dark Strong, but it will be interesting to see how this malt plays out in a Tripel. The beer came out of the boil kettle a dark amber, so I'm hoping the flavor isn't overpowered by this malt.
Once the equipment I have ordered for the fermentation chamber arrives, I hope to keep this fermentation under control as I add the additional cane sugar needed to dry out and strengthen this brew. Then, I may or may not repropagate this particular yeast, and either try brewing a dubbel or dark strong for the colder months.
