After pitching the yeast, you must be as careful as possible when transferring/moving the beer as it may cause oxidation as mentioned. When you use a funnel to transfer the beer into bottles it's going to splash and be very turbulent which will introduce oxygen into it. The best way around...
Unless everything is absolutely perfect, it is very possible to get some husk/grain through your false bottom as you vorlauf. It will settle to the bottom of the fermentor.
That being being said, how big are the holes in your false bottom?
Are you grinding your own grain or buying it...
If I were to experiment with single hop for the sake of experimentation, I think I would do extract just for the ease and consistency between batches. I think I could knock out a couple of those in one day where I wouldn't want to brew more than one whole grain batch in a day.
You don't use a lot of water to rehydrate yeast, so by the time you pitch it, it will be around room temp. I usually rehydrate near the end of boil because it takes me at least 20 minutes to cool the wort.
Same. Not sure how seasons change the way a beer tastes or changes the experience. I just think it's a concept that has been around for awhile that people still hold onto. Like don't wear white after labor day.
If your gravity readings are right then your abv is only going to be about 1.7% if you don't do something. You are obviously going to have to get the fermentation going again which will involve getting it back to room temp and re-pitching.
How long did you let it ferment?
