I like beer.

comment Calculating Alcohol by Volume
Agree with the fact that it isn't a linear relationship. Beyond the simple case of a simple sugar solution fermenting into ethanol it get real complex. Remember, there are a lot of other things in beer that can affect both gravity and refraction. Unless you have a real need for it, use the simple (OG-FG)*131. Its good enough for homebrew.

comment Triple Fermented?? But Why?
I'm not saying that adding the same strain twice makes any sense. It is just a possibility.

comment Triple Fermented?? But Why?
I know of two Belgian beers that use a second strain at bottling. That to me qualifies as a 'few'.

comment Final Gravity on the Refractormeter vs. the Hydrometer
Not the same question. I know what a hydrometer and refractometer are. I'm aware that corrections are needed using a refractometer. What I'm trying to find out is how to account for having two batches have the same FG with a hydrometer by different by the refractometer.

comment Triple Fermented?? But Why?
BTW, this reminds me of the Miller Lite marketing campaign 'triple hops brewed'. Marketing. I hope I'm wrong.

comment What are some popular methods for measuring boil and HLT volume?
Someone correct me if I'm wrong, but doesn't water expand to nearly 110% of its cold volume as it approaches boiling? This is more than a little off. Whether you use a sight glass or a wooden dowel, you should know how much water you are adding at each stage and pre-calculate for water loss (to grain, pump, floor, etc.). Part of this is well know (grain loss). The rest are usually empirical. Each time you transfer liquid from one vessel to another (using a pump and hoses), you will lose some.

comment Alternatives to a hydrometer?
Also note that all refractometers of the same style should cost the same. Regardless of which scales and how many they print inside the view finder. If someone is charging more for the refractometer that has %Brix and SG scales vs. the refractometer that just has a %Brix scale, then they are ripping you off.

comment Alternatives to a hydrometer?
Agreed. I edited my post to clear things up a bit. I was referring to having to do more math to go from OB and FB to ABV.

comment Can I use my Country Living Grain Mill for homebrewing?
Then I would just run some malt through it to see how it comes out. Can you adjust the roller distance on your mill?

comment What's the point of going all-grain?
Mike is right. All grain brewing will make you a 'better' brewer. You stop making other peoples' recipes and start thinking about making your own beer. The number of variables you can control during mash is incredible and forces you to really think about what you are trying to make.

Indeed. Plus, get one that is marked in %Brix and SG. That way you don't have to do any conversions. Also agree on using both for a while until you get the hang of it all.

comment Carbonating Kegs In Quantity
OK. Yeah. I wanted to avoid buying too many LP->LP regulators. So using manifolds for kegs that can carb to the same volume is probably the best way to go. Any idea about flavor transfer? Friends of mine swear that you should have check valves inline on the CO2 so that you don't get Belgian taste on your IPAs (and such). I've never noticed this in my beer fridge which has three service lines without check valves.

comment Bubble, Bubble, Toil = Trouble? Brewing's Carbon Footprint
Water wheels made from hand sawn wood? Oh, I forgot they had to make the saw and it had a carbon footprint... =)

comment What wattage element is needed for hot liquor tank/heat exchanger, and what about brew kettle?
@Mlusby Is there a way I can send you the info privately? I don't really want to put a complete design out there. Mostly I am afraid of the liability in giving someone a bad circuit design. While I am confident in my design, I don't really want to be even remotely responsible if my design ends up burning someone's house down or electrocuting them. We are talking about a 50amp 220V circuit design after all.

The advantage of the controller is the ability to 'set it and forget it'. It is nice to set the controller to your desired mash-in water temp and then walk away to grind your malts and take care of other tasks. Whenever you are done and ready to mash-in, you find your water is waiting for you. Good PIDs are pretty cheap. Just make sure to get the right size relay and heat sink.

Thanks for posting that formula Morgan. I had it in my notebook, but unfortunately, the notebook isn't close at hand. However, I would question why anyone feels the need to go from mash out to boil in fifteen minutes? You have to ask what you are trying to accomplish. Is thirty minutes acceptable? Are you really concerned about fifteen extra minutes spent brewing beer at home? The phrase 'relax, don't worry, enjoy a homebrew' comes to mind.

comment Boiling with lid on or off?
What Greg said in the answer below. But to clarify. A typical pot geometry will lose 9-11% volume per hour. However, that is dependent on environmental humidity (and to some degree temperature too). Your evaporation rate will be lower when it is humid. Recipes are designed with this loss in mind and should have a higher starting volume. I.e. a ten gallon batch will start with about 11 gallons of extract at the start of a 60 minute boil.

comment How do I keep yeast from a strain that I've bought?
No problem. Don't worry about genetic drift in beer yeast. As I understand it Saccharomyces cerevisiae does not drift much. You're main worry as a homebrewer is contamination. As to how to store it longer than a few months? I don't know. I've never tried. My experience is mainly with making the same recipes repeatedly and trying to save money. Also, don't underestimate the yeast colony's ability to 'learn' a beer. Often times, your beer will improve noticeably after the yeasts have fed on the same recipe a couple of times.

comment What are the advantages and disadvantages of Buckets vs Carboys?
I was being a bit ridiculous about it when I wrote that. But yes, the handles and the carboy carriers (the cargo net type) make them much easier to carry. I still ended up with a stress fracture in one. I suspect I bumped it against something when setting it down one time. I don't trust that carboy now. Glass is a strange beast.

comment How do i determine the quality of ingredients?
+1 for the comment about bittering hops. I buy my bittering hops in larger packs. I'll use some on a brew and put the leftovers into a Ziploc freezer bag and back into the fridge. They will last that way for a couple of weeks no problem.
