Question for all of you who are able to control your fermentation temps: what is your fermentation temperature profile for a single stage ale? For example, I like to pitch at 68F, then after two days or so when the airlock starts to slow I'll start raising it by 1F every day to a maximum of 72F...

Wanted to do something simple. This is a SMASH + East Kent Goldings English IPA recipe - feedback much appreciated! Type: Extract Batch Size: 5.00 gal Boil Size: 6.52 gal Boil Time: 60 min Ingredients 6.52 gal Distilled Water 10.00 g Gypsum 1.5 g Chalk 1 tsp Yeast...

When using a yeast calculator such as http://www.mrmalty.com/calc/calc.html does the liters of starter figure refer to the amount of starter wort you make to pitch the initial yeast pack/vial into, or is that how many liters of yeast slurry you should be pitching into the final wort after...

That will work - I was clearly over-thinking it. Thanks for the perspective!

I have this O2 welding tank from Harbor Freight - it has a CGA 540 male outlet valve: http://www.harborfreight.com/20-cubic-ft-oxygen-cylinder-92810.html And I have a Precision Medical oxygen flow meter - I think it has a 1/8 NPT female inlet. Is there an adapter or something else I can...

Thanks for the replies! I'd also add that there doesn't appear to be a lot of consensus on what over-oxygenating might do. On Brew Strong Jamil and John said that it can introduce fusel alcohol and acetaldehyde off flavors. I've also heard that it can cause oxidative damage to yeast cells...

Thanks! That helps a lot :)

I know, right? I've been doing the same as you - 45-60 seconds for a 5-6 gallon batch. But doing that math makes it seem like I'm adding way too much O2... The beer tastes fine thought and that's the most important part!

I use a sintered diffusion stone and pure O2 to aerate the wort prior to pitching and fermentation. I ran some back of the napkin calculations and wanted to check that I'm on the right track with how long I should be aerating: I'm aiming for 8 ppm (=8mG/L) in a 5 gallon batch (it helped me...
