Sulfate is the only number out of range, but since I'm trying to accentuate the hops a little bit, I'm fine with it being higher than the recommended 70-75.

4/23/2013 1:55 AM over 13 years ago	+1	Brew Day Complete	1.048	20.9 Quarts	2/20/2021 3:43 AM over 5 years ago	~3 quarts of liquid with lots of trub in kettle - some lost volume.
4/25/2013 6:51 PM over 13 years ago	+3	Other			2/20/2021 3:43 AM over 5 years ago	Fermentor at ~75º when yeast pitched night of 4/22. Placed outside wrapped in wet towel. Fermentor at 65º morning of 4/23, rapid bubbling. Fermentor at 64º evening of 4/23. Fermentor at 64º morning of 4/24. Fermentor at 62º evening of 4/24. Bubbling slower, comes inside. Fermentor at 63º morning of 4/25. Bubble every 2-4 seconds. Fermentor at 64º evening of 4/25.
4/27/2013 9:04 PM over 13 years ago	+5	Sample	1.011		2/20/2021 3:43 AM over 5 years ago	Carboy now in closet temp is 67. Nice taste, and the NS gives almost a white wine like after taste. I think the beer can handle some light dry hopping and citrus peel.
4/28/2013 8:40 PM over 13 years ago	+6	Other			2/20/2021 3:43 AM over 5 years ago	Fermentor at 67º afternoon of 4/28

5/6/2013 4:07 AM over 13 years ago	+14	Fermentation Complete	1.010		2/20/2021 3:43 AM over 5 years ago	First taste... loving this beer. I think the amount of Citra is right on. The NS stands out on the finish... will be interesting to see how the beer develops, because there's a solid note of sauvignon after the swallow. Not unpleasant, but I haven't decided that it isn't too strong yet. Put a few pieces of mandarin zest into my taster, and I think that helps accentuate the citrus nature of the beer. Infusing the zest of 2 mandarins in ~1/2 shot vodka.
5/8/2013 9:15 PM over 13 years ago	+16	Other			2/20/2021 3:43 AM over 5 years ago	Moved secondary carboy back outside with wet towel, getting temp closer to 65 instead of 69 in closet.
5/12/2013 4:04 PM over 13 years ago	+20	Packaged		5 Gallons	2/20/2021 3:43 AM over 5 years ago	Bottled 184 oz unaltered. Bottled 452 oz with mandarin zest/vodka... probably added 1Tbsp zest/vodka mixture (Tasted to make sure it was detectable but not too strong. Left out most of the vodka. Seems like the total volume was 5.2 gal, but bottle volume only added to 5.
5/26/2013 4:15 PM over 13 years ago	+34	Tasting Note			2/20/2021 3:43 AM over 5 years ago	Wow! Great beer. Right amount of citrus. Clean, lager-like finish with a touch of the Nelson providing a crisp sauvignon-esque taste. Brilliantly clear.

Notes

Starter: 1 L of 1.050 OG. 5.0 oz DME (137g) in 1L H2O yields 297 x10^6 cells.
