If you brew often enough, divide the "extra" starter into multiple small jars. That reduces your generation count. Treat the small jars as vials when making more starters. When you get to the last one, repeat the process.
Don't add it too soon if you like your ceiling. Best (worst?) blow off I've ever had, bar none, was a cherry ale. A lot of people that don't recommend secondary will suggest that adding fruit IS a good time to use a secondary.
Fruit flies are attracted to CO2. Why again shouldn't people use vodka in an airlock?
The vodka should have killed and acetobacter on the fruit flies. If not, make some fish and chips
One of my three piece airlocks that is being used on a room temperature ferment has two fruit flies steeping in the vodka. I would say they can get through the holes in the top. Maybe you could rubberband a piece of cloth or paper towel over the top if you want to run without the lock part.
If you want a high attenuation, mash longer or do a two step mash. I would start lower than 150.
There is no point in doing a mash out in biab. Pull your bag, start your burner and let it rip. You can muck around with the bag while the majority of the wort is coming to a boil.
Any ale i can see through with a 5 minute, 1 minute, flame out, hop stand or dry hop does not benefit from leaving it in the primary past it being done. I paid for those hop aromas, i would like to enjoy them.
Why is it the best way? More work and you remove the functionality of the original unit. Take a wine bottle fridge. You covert it , brew a beer and for whatever reason you immediately move up to a 28 cu ft freezer. Or maybe you're free cycle chest freezer dies a month later. Lot of wasted...
That is,just a list of typical uses. They specifically say "food grade" in the title. I would buy and use them.
Fyi, fish are much more sensitive than humans. They die right now a when their water is contaminated. I feel safe with the purity level of anything that is made for aquarium use.
So confused. You either filtered or you didn't. Either way there doesn't seem to be anything in your pictures that is concerning. It looks like coagulated proteins and yeast doing a happy dance :ban:
Could it be the mean temperature in Thailand is a little bit warmer than we like to keep our houses? Or could it be the dessert that is made with the rice? The rice isn't terribly appetizing looking at week 3. Maybe you could ask your mother in law about the amount of water used when making...
Adding water to it will make it a nice culture medium for science projects. You won't have enough alcohol in it to be safe.
There are a lot of things you could try if the reason is because you mashed at too high of a temperature. None of them necessarily worthy of consideration. These are...
