3/11/2018 4:08 AM over 6 years ago	+2	Mash Complete	1.046	5.8 Gallons	2/20/2021 3:43 AM over 3 years ago	I read Bru'n water wrong and thought it calculated adding 69 mL of 10% phosphoric. I used 50 mL and it shot the pH down to 4.6. Then I added about 5.8 g of baking soda and it shot up to 6.9. Then added about 15 mL phosphoric to bring it down. At least on the first time with a new recipe. Final mash pH 5.38 LESSON: Once again, use half of what any calculator suggests as a precaution, then adjust.

3/11/2018 4:11 AM over 6 years ago	+2	Yeast Starter	1.040	2 Liters	2/20/2021 3:43 AM over 3 years ago	Pitched almost entire starter after cold crashing for 6 hours. Poured off top layer that looked less cloudy.
3/11/2018 4:17 AM over 6 years ago	+2	Other			2/20/2021 3:43 AM over 3 years ago	Strike temp calculated target was 154.9. I got 154.4 and the temp at 10 mins was 148.6. Right on the target of 148.
4/1/2018 7:13 AM over 6 years ago	+23	Fermentation Complete	1.013		2/20/2021 3:43 AM over 3 years ago	Was very clear during the transfer, perhaps the most clear I've seen it at this point. Taste was surprisingly good. Can't tell if there is additional sodium. Sulfur is on the back end. Maybe that will diminish in lagering.
5/2/2018 5:16 PM over 6 years ago	+54	Tasting Note			2/20/2021 3:43 AM over 3 years ago	Very clear right off the bat. Only dumped two pints. Hints of corn and sulfur in the aroma. Grainy sweetness and slight corn in the taste.

Notes

Strike temp target is 154.9 F.
