Ingredients / Water Question
« on: February 06, 2019, 05:15:01 PM »
So I have a recipe I got from a brewery in the area for an awesome Hefe. I've just started with tweaking water and have a question about trying to match their water. They use RO water and the recipe says that they add 4:1 Calcium Chloride to Gypsum. I do not have access to RO water. How would I go about adjusting my water to match this, or approximate it. 

My Water:
Calcium: 59.1ppm
Magnesium: 6.06ppm
Sodium 69.4ppm
Sulfate 95.1ppm
Chloride: 59.3ppm
Bicarbonate 117.12ppm

I carbon block filter it before use.


General Homebrew Discussion / Trying to determine source of off flavor
« on: October 11, 2018, 03:42:22 PM »
So several, but not all, of last few batches have come out with a similar off flavor, and I am trying to determine what caused it. The flavor is to me a green sort of grass flavor.

From what I have found online the closest thing I can find that would cause this is improperly stored hops. I keep my hops vacuum sealed and in a freezer when not being used. I have read that they should stay good for a fairly long time. The hops I used were in the freezer ranging from around a year for one batch to a month or so in another. So I am not sure that is the issue.

I had another thought, but can't seem to find any information on rather it would cause such an issue. I did a yeast starter for all the batches, and just let it sit on the stir plate at room temperature, and it being Texas summer that temp may have hit the high 80s during some days. Could that cause an off flavor like this?

I'm planning a brew day for next Weekend, and going to rebrew one of the recipes, but stick the stir plate in my fermentation fridge, and see if that fixes it, but was wondering if anyone had an insight about off flavors from too high of starter temps.

Also if anyone has any other suggestions as to what would cause it I appreciate it.
