I've got 2 unrelated questions.
#1. What is Renners hoping schedule for his CAP, "Your Father's Mustache"? Here is a snip from his recipe;
25 g. Cluster hops pellets @7.5% - 1hr boil
1/4 oz. Styrian Goldings @5.2% - 10 min. boil plus settling steep - 15 min.
1/4 oz. Styrian Goldings @5.2% - 15 min. settling steep.
The Cluster addition is straight forward but not sure what a settling steep is for the Styrian Goldings
#2. Purchased a pH meter and wondering if I there is a reason to not save the calibration solution after calibrating. I rinse the probe with tap water and shake it dry between cal. settings. |

I believe he means to add the Styrian Goldings in the last 10 minutes of the boil and at flameout. It appears that he whirlpools the wort and lets it stand for 15 minutes before chilling.
The pH buffer solution will absorb O2 from the air and change over time, rendering it inaccurate for calibration. However, pH 4.01 buffer makes a very good storage solution for the electrode. |

Got ya on the CAP hopping. I wasn't clear with the question about calibration solutions. I have 2 small bottles, maybe 6oz or so for calibrating the high and low points. The probe won't fit in the bottles so I dump a small amount in clean vials. After calibrating is the solution useless or can I pour it back in it's original container. It just seems a waste to pour it down the drain. |

If you keep the calibration solution undiluted and uncontamined it can be reused. However, this is difficult because you typically rinse the probe in ordinary water, some of which remains on the probe and slightly dilutes the solution. I'd call it a false economy to reuse the very small amount of solution needed for calibration. You can purchase a bottle of calibration solution relatively inexpensively from a lab supplier. |

Well, guess I'm cheap, think I'll keep the spent solutions in a separate container and make a comparison between the original and spent, when the original is nearly gone. Also I'll look for a better quantity/price relationship the next time I purchased cal. solutions. |

Here's Jeff's hop schedule taken from the version of YFM that I have used with tremendous success:
First Wort Hops: 3 HBU Saaz or other noble hops (3.2 HBU for pellets)
Bittering hops: (60 minutes) 5.3 HBU whole
Cluster (4.8 HBU for pellets)
Flavor hops: (15 minutes) 1.5 HBU whole noble hops or Styrian Goldings (1.2 HBU for pellets)} |
