Hi all, new to this thread and Homebrewtalk generally. Some quick background for reference. I have been homebrewing for five years, only getting more and more avid, with 62 brews completed. I share a 15 gallon system I built over the years with a friend, but have been using a Brewzilla for the last couple of years for solo, experimental batches. Given my predilection to brewing, I decided to invest in the 20 G Spike Solo + recently to take advantage of the 220V power and the potential of larger batches. Got a great bargain bin deal but do wish I had just gone with the 15...prior to purchasing I didn't think I could do full 10 gallon batches in the 15 not realizing I just couldn't do HUGE 10 gallon batches. Oh well. I have done 5 batches in the Solo and am starting to learn its ways. I have a couple of overarching thoughts and some questions I thought I would pose to the group.
Thoughts:
-Brewing 5 G batches on the 20 is tricky. I switched to no sparge for the first time ever using Brewsmith software for grain/water estimates. Otherwise the grist was so dry it was ridiculous.
-I just always mash for 90 minutes now - especially if using Pilsner malt. Otherwise my mash efficiency was spotty as others have noted.
-Doing a 90 minute boil is also tricky. My wort gravity is always way below the Brewsmith or my own estimate or previous experience, but my OG is way high (and wort volume way low) after a 90 minute boil, even if I lower the element to 70% as recommended by Spike. So I end up adding even more water to the mash, which lowers the wort gravity even more! This thing is tricky...my Brewzilla and the big 15 gallon system are just so reliable and predictable....
-End of boil waste is so high. Between the kettle deadspace and hoses, it really compounds the above issues. I read some folks actually drain the kettle through a strainer to up fermenter volume. Lifting the 20 with a couple gallons of liquid in it alone seems daunting though.
So, on to questions:
-Has anyone attached their pump directly to the kettle output? Would have to remove the butterfly valve and rely upon the pump valve I guess? The Uni-Brau is set up this way.
-I use an Exchilerator and like the water savings by racking directly into the fermenter rather than recirculating...but since the whirlpool never gets a nice chill to it, my kettle is full of loose trub at the end of the boil that I either pump into my fermenter or have a BUNCH of waste. What do you all do about this?
-Has anyone come up with a good hop/trub blocker for the outlet of the kettle to help alleviate this? My first batch I used whole cone hops thrown into the kettle and the Exhilerator clogged within about 15 milliseconds. THAT was quite the first brew day on the Solo.
-And has anyone made some sort of sparge fitting for it? Given relatively low mash efficiency, coupled with a clear (no pun intended) need of a good long vorlauf to keep the boil relatively free of husk material, it seems like it would be a good thing.
-Lastly, Spike, if you ever look at these posts, have you considered a kettle hop/trub attachment for the kettle output or a sparge fitting like some of your competitors have? If not, you might want to consider it...
All for now, thanks in advance for the information dump! Super excited to be part of this.
And total side note - if you are in the Portland, OR area and are interested in setting up a yeast sharing program, let me know. I hate to dump great yeast just because I won't be brewing a certain style for a while. I have a conical so harvesting healthy and happy yeast is super easy and I am happy to share.
Thanks all,
Tobin
