I finally got a chance to brew this evening.
Recipe basically the same was posted before except a few minor things.
I only used half gallon of grapefruit juice, since I brewed a 4 gallon batch instead of a 5.
The Northern hops are the same, but for the Cascade I only used 1/2 ounce, and they are leaf hops where the others are pellets.
The ginger, as you can see in the photo below I used quite a bit, it weighed in at 5.5 ounces matter of fact. You can also see the left over ginger root, I used about half of that root. I ran it through my food processor twice. I'm sure grading it would have been fine but I bought this Kitchen Aid food processor and so far only the SWMBO has got to play with it, so daddy had to play with his toy! I added the ginger about 2 minutes before flameout and WOW, it REALLY came alive. It SMELT LIKE Shiner's! Now I may have added way too much, but I certainly wasn't going to settle for too little, since I weighed it instead of using volume, I think this will be more accurate when I make adjustments on the next batch.
I did have one problem unfortunately. I've been using a new burner, and I had to boil for 2 hours to get even close to my target volume, which in this case was 3.5 gallons, because I accounted from the grapefruit juice in the fermenter. When it finally got to 4 gallons I shut it off and began cooling, it was getting dark outside and the bugs were about to be in full force, did not want to take any chances of infection. 4.5 gallons went into the fermenter and the SG is 1.038.
As I'm sure you know living in the south, I was only able to get the wort temperature down to 85 with my immersion chiller, so I will pitch yeast in the AM, when it reaches 55F.
I will report back soon!
