It’s been a while since I did this one and the first time I did this as an experiment in “Reiterated Mashing”, but this time with a 20gal mash tun, there was no need to split the mashes. This was a 10 gal batch that I used essentially the same recipe:
Batch Size: 10.50 gal
Boil Size: 11.70 gal
Estimated OG: 1.080 SG
Estimated Color: 3.9 SRM
Estimated IBU: 15.7 IBU
Brewhouse Efficiency: 60.0 %
Boil Time: 45 Minutes
Amount Item Type % or IBU
30.00 lb Pilsner (2 Row) UK (1.0 SRM) Grain 75.0 %
8.00 lb Rice (1.0 SRM) Grain 20.0 %
2.00 lb Pale Malt (6 Row) US (2.0 SRM) Grain 5.0 %
3.00 oz Saaz [4.00%] (45 min) Hops 15.7 IBU
Munich Lager 2308
For the rice, I used off the shelf rice for this and cooked it before I was brewing this morning. I burnt some of the rice so I didn’t use that stuff in the mash. I cooked it like I would for a big batch of rice. It worked well enough. The mash lasted for 70min at 150f, it dropped about 3 or 4 degrees over the time, not bad considering it was in the teens in my garage.
The first running were 19brix (1.079) totaled about 6gal (out of 12.5gal of strike water). I only ran one sparge because the pump ran through the water pretty fast. The second running was 14brix (1.057) and brought the whole volume up to about 12 gal total. The pre-boil gravity was 18brix (1.075).
I dropped all 3 oz of hops in for the 45 min and let it go. No boil overs and a 1.074 OG made for a great brew day (I know, don’t ask me, there must have been a bad reading on my pre-boil gravity).
After airating and adding the four Beano pills per 5gal, I pitched the yeast and now it’s waiting to see the temp of my secret lager corner in my basement. I have to get my hands on some Kaffir Lime leaves for the secondary.
One quick note is that this was my first time using my brew tower pictured above. It worked awesome. There are wheels on it and it has breaks. It’s a sturdy tower and with my pump in my system, it allows me to do most of my brewing without having to hoist my mash tun up and down a bunch of times. Plus it doubles as an organizer for my keggles and burners.
That’s about it for now, cheers.
