Brew #7 - IPA

This week we decided to remake our IPA with the correct calculations (so we can get a BG of 1.060). We also converted a rubbermaid ice chest to a lauder tun. Some bumps along the way but Lisa had an idea to fix the spigot. A bit of plumbers tape later and we have a tun. 

Ingredients


After figuring out the miscalculation; we went back to the drawing board and came up with the correct recipe. The ingredients are as follows: 

RequestedUsed
0.8lb Crystal 40oL0.8 lb.
7.5lbs. Pale Malt7.5 lbs.
2.25oz Chinook (13% AA)2 oz Chinook(14.3% AA)
0.25oz Chinook (12.2% AA)
1oz Cascade (5% AA)1 oz Cascade(5.9% AA)
Any American ale yeastEast Coast ale yeast

Mash Method


December 29, 2007
Heated 4.15 gallons of water to 170oF.
Pre-heated mash/lauter tun with hot hot (145o) tap water.
Added grain bill, and slowly added about a quart of the strike water at a time.
T=60
Initial mash temperature is 159F.
T=45
Mash temp 159F.
T=30
Mash temp 154F, added 1 qt boiling water mash temp 158F
T=15
Mash temp 155F.
After a few tries at lautering the wort (our filtration was less than spectacular), we (meaning Eric) thought of a great idea where we put some of the grain into a strainer over the boil pot, and filter out of the spigot right over the grain bed, using the bed itself as a filter. This drains into the boil pot. Then, after the boil pot filled somewhat, filtered that back through the grain bed into the lauter tun again. Repeated filtering through the bed into the boilpot.
Sparged with 4 gallons of ~150o water.
Ended up with about 8 gallons of wort in the boil (presumably including some degree of grist).
Brew Method

December 29, 2007
T=60
Added 1.5oz (14.3%AA) Chinook
T=30
Added 0.5oz (14.3%AA) Chinook
Added 0.25oz (12.2%AA) Chinook
Started ice bath a lot of snow and some water to get it melting
T=15
Added 1tsp irish moss
Inserted wort chiller for sanitization

After the boil, we cooled the wort to pitching temperature in about twenty minutes. Whirlpooled the wort to get the sediment to settle conically in the boil pot, and racked from the side into the primary fermenter. This ended up being moot, since the sediment all found its way into the fermenter anyway. I don't believe we kept ANY out. Still need better filtration for the lauter.

OG reading was 1.044, versus a predicted 1.060. This tells us a few things. We're either getting real bad saccharification in the mash, really bad mash efficiency, or really bad extraction. Anyway, we're not getting enough sugar in the wort.

Fermentation


December 29, 2007 
Pitched our yeast following cooling and racking, and put in the basement to begin fermentation.

Took a peek at the fermenter, there's a bubble popping out of the blowoff every second. The krausen has begun, it's covering the whole surface of the beer but isn't quite thick yet. There looks like there may actually be more sediment at the bottom of this one than the last one??? Definitely need better grain filtering. Dammit.

Racked to secondary and added the ounce of Cascade for dry-hopping! This looks really nice, clear and has a nice smell to it already. 

Bottling

January 26, 2008 
Got our FG reading, 1.012. Best attenuation yet! Woohoo! With a 1.044 OG, that gives us an abv of 4.3%. Rock! We got 24 bottles and a couple glasses to drink as well. Bam! Give 'em a couple weeks and we'll see how they taste!

Notes

  • Think of a better way to filter the lauter!!!
