Zymurgy / Problem with White Lightning Recipe, Vol 35, No 2 (current), pg 20

« on: March 18, 2012, 09:19:00 PM »

Just finished brew day on this recipe and had some problems with my OG. I did the extract option, steeping .5# of flaked oats and Carapils. My OG came out low. Looking into it I find that Carapils has no diastic power but flaked oats needs to be mashed.

Is this recipe correct or is this a mistake? I may end up throwing out this batch and keeping my Muscat concentrate for a future one.

General Homebrew Discussion / Really bad O.G. from specialty grains - any chance of a redo?

Using a recipe that's 4 # of LME, .5 # of flaked oats and .5 # of carapils. Expected O.G. was 1.045 and I had 1.030. I plugged it into hopville and confirmed 1.045 was correct.

Since these are specialty grains with no fermentation, could I potentially re-steep and boil these in a 1 gallon batch and pitch to secondary? Or if I can get it in soon enough, primary. Right now it's only 4 gallons so I have room for that.

I think my oats clumped together and I hadn't noticed until I threw them in the trash.

General Homebrew Discussion / Brewing with Muscat Grape Concentrate

« on: March 11, 2012, 05:27:52 PM »

This week I'm brewing the White Lightning Recipe in Zymurgy pg 20 and had a few questions.

For all grail it's 5# of grain, and then Muscat Grape Juice (4#) added after primary fermentation.
For extract, it's 1# of grain and 3.2# of DME. Muscat Grape Juice is added to secondary.

I will be doing the extract version with wyeast witbier.

First, why the difference in the grape juice addition? You have less trub with extract and it seems like it could be added to primary as well.

Second, it seems odd to add 4# of fermentable sugar after primary. Won't this force the active yeast to go through another fermentation? With less vitamins and oxygen they'll be stressed and produce off flavors. It seems better to add the juice 2-3 days into fermentation when most of my yeasts are still active.
