General Homebrew Discussion / Re: Overshooting ABV

White Labs was working on correlations for all of their yeasts to better estimate FG.  Not sure what the status  of that research is.

But how can they know what your wort is like?  Using the same yeast I can get from 60-80+% attenuation depending on the wort.

The correlations were supposed to include mash temp.

I believe that you would only need to treat the hot water.  Your faucet issues are from precipitation of calcium and magnesium salts.  Calcium salts (and possibly magnesium salts) exhibit reverse solubility; they are less soluble at warm temperatures than at cold temperatures.

Getting a good FG estimate from Beermith is pretty unlikely (I don't use Beersmith's mashing profiles).  I make my own best estimate for FG from experience.  Would be interesting to see if other software does a better job, but I doubt it.

Questions about the forum? / Re: AHA Forum Topics
« on: December 18, 2013, 08:53:35 PM »
I do like the new look.  Could I get the best of both a list of topics (new homepage) and a list of posts on the homepage (old homepage), plz?  The list of topics should change more slowly than a list of posts which makes it hard to tell if there are new posts for a topic I'm interested in but did not post to.  Would it be possible to indicate the number of posts for a topic or time of the last post in list of topics on the homepage, plz?  Thanks for considering my idea.

Updates to the topics appear to be few and far between on the homepage.  I'm not sure if the list of recent topics is being updated properly or if forum traffic is down.

I didn't appreciate that the new homepage has a list of recent topics, which should change less frequently than the list of recent posts on the old homepage.

I hadn't recognized the difference between posts and topics.   Topics is better, but it'll take getting used to now that I'm used to a list of posts.

All Grain Brewing / Re: Decoction yields greater?
« on: December 18, 2013, 10:39:11 AM »
Always assumed the increase was for 2 reasons:

1. You usually use a higher water/grist ratio
2. You increase mixing during the mash

I also assumed I was seeing the increase because I had poor efficiency in the first place (~63%). Potentially a  system with a higher average efficiency wouldn't see a difference...
The boiling bursts small hard starch granules and makes that available to the enzymes, so higher conversion efficiency. Kai has information on his page, and a microscope picture of a granule.

Some starch does not gelatinize at typical mash temps, but I believe that this boost in efficiency is small for barley.  I believe the bigger effect comes from the additional mixing when the single infusion conversion efficiency is low, typically due to coarse grind.

The list of recent AHA Forum posts on the homepage (http://www.homebrewersassociation.org/) hasn't changed once since yesterday.  It is driving me crazy! (or crazier)

What do you mean by batches?  Different batches of the same recipe? 

Re FG, I am using BeerSmith 1.0 and I'm pretty sure that it won't give me an accurate FG for saison.  Perhaps BeerSmith 2.0 is better.  My gut is that FG estimates work only for "normal" ales in the various softwares, not for Belgian yeasts at higher temperatures.

Do any of them explicitly support parti-gyle?

Wow, boiling 2 gallons down to 1 pint is pretty radical.  I boiled down 2 gallons to a little over 1 quart when it the boil started to act up and decided I didn't want to watch over it much longer or risk burning it.  Next time I might boil down further.

Did my Scottish 70/- this past weekend doing a single infusion mash with 1.5 qts of water/lb grain.  For most of the concentrated boil the temp was 212 F and the boil looked "normal" for boiling wort.  After reducing the wort by half, the temp began to rise slightly.  After reducing the wort by about 2/3 the boil changed noticeably because the bubbles didn't burst and the volume of the wort with bubbles suddenly doubled in size.  The bubbles were brown, not white foam.  The temps were fluctuating rapidly between 217-219 F because one moment my thermapen probe was in steam and the next it was in wort. I stopped the boil and added some wort from the main boil which made the whole thing easy to pour out.  I got some nice toffee flavor from the concentrated wort.  The concentrated boil added a lot of extra time to the brew day because I collected about 2 gallons of 1st runnings for a 10-gal batch.  Next time I'll put the concentrated boil on the biggest burner of the kitchen stove since burning doesn't appear to be a factor until most of the water has evaporated.  Maybe I'll collect 1-gallon of 1st runnings and add a little DME as a shortcut next time.

All Grain Brewing / Re: Single Infusion Mash Time
« on: December 17, 2013, 08:22:28 AM »
60 minutes is normal for me in part b/c I get a break to do other stuff when nothing is happening, not even a burner running.  I do tend to start the vorlauf before the 60 minutes are up and generally skip mash out.

If your normal mash efficiency is low, you can get a large increase in mash and brewhouse efficiency from decoctions.

Equipment and Software / Re: Old Coolers
« on: December 11, 2013, 01:19:47 PM »
I'm not aware of any problems with older coolers.  Getting a good seal for your drain is a pain if you have to alter the cooler.  If you are lucky, the copper tubing and keg grease will fit perfectly through the existing drain port. My orange, round mash tun had a fairly short life span before it started cracking.
