All Grain Brewing / Re: Water salts influence on aroma?
« on: March 27, 2016, 07:16:32 PM »
I don't think there is much direct effect of salts on aroma.  pH can influence the solubility of aromatic compounds, but changing pH probably has a stronger effect on flavor.

I think that unholymess is pretty much crock on making invert. Ron Parkinson's guide to making vintage beers has better instructions.

All Grain Brewing / Re: Mash steps/Beer body/Fermentable sugars
« on: March 25, 2016, 06:15:36 AM »
Why are you mashing at 60C (140 F)? You are converting almost no starch into sugar at that temperature.  In contrast, 65 C (149 F) is a useful mash temperature.

Secondary should be an exception rather than the rule.

Kegging and Bottling / Re: Picnic taps
« on: March 24, 2016, 07:34:31 AM »
I haven't notice any funk in the tap.  I do a thorough disassembly and cleaning between kegs and drain the tap between pours.

The taps unscrew and I have found that the taps can get loose causing leaks.

Kegging and Bottling / Static mixers
« on: March 24, 2016, 07:25:50 AM »
I use 74695A12, a little cheaper and a little longer.  I'm still experimenting with it but I think the ideal system for me is 1.75 static mixers in 0.3 m (metric my friend!) of 1/4" line for 15 psig (~202 kPA absolute).  I have not tried them in a dip tube as having them in a line is better IMO because you can see if they are picking up hop debris and easily remove the line for cleaning.

The Pub / Re: Belgium replies
« on: March 23, 2016, 07:35:54 AM »
I am glad to say that the other Belgian passion, bicycling, is in full swing.  The Dwars door Vlaanderen started in Roeselare without security incidents.  For the Belgian hopefuls it must be very emotional to be riding today.  The Belgian Greg van Avermaet is a major favorite.

Frank, do you watch much cycling?

My condolences.  My distant Belgian relatives report that that they are safe.

My understanding is that IBU estimates are for the fresh wort so its not surprising that the IBUs is the finished beer are substantially less.
That is not my understanding. Can you point me to any reference to that? I am willing to read and learn.

My own experience was that Tinseth is the most accurate on beer samples.

 Yeast selection can have a big influence. My samples used ones that were close.

My understanding may not be correct.  I don't see anything reliable to point too with a quick Google search.

Edit: My understanding appears to be non-substantiated.

All Grain Brewing / Re: Not converting??
« on: March 21, 2016, 07:25:12 AM »
Iodine tests are basic chemistry and very reliable. If your mash is well mixed and there is starch, the iodine turns black. That said I don't use them.

Too many adjuncts for the diastatic power of the Vienna. Vienna is only 50°L and most sources say 40°L is the minimum required for self conversion. That means it could barely handle its own starches before you threw 28% flaked corn in the mix.

MFB Vienna exceeds 100°L, but I agree that the diastatic power of the Vienna used is the first suspect.

Ingredients / Re: Whole Coffee Beans
« on: March 18, 2016, 06:35:08 AM »
I used 2 oz in a porter and was very pleased. I could taste both the coffee and the porter. While carbonated alcoholic coffee is tasty as a novelty, if I have to drink a keg of it I want to taste beer and coffee.
 
I added whole coffee beans to the serving keg and kept it in there for 1 or 2 days. After a few weeks the coffee faded and left a weird aftertaste.  I think I would have been better off using a smaller amount of coffee and leaving the coffee in the keg until the keg kicked.

If you live somewhere cold enough, an aquarium heater, ice packs and a water bath can do the job.  That way you can save money for kegging.  Of course, there is always a need for more gadgets.  Since I already do water baths and kegs, I'm waiting for a fridge or freezer to come my way for even better fermentation control.

Wood/Casks / Re: Cask Condition?
« on: March 17, 2016, 03:10:26 PM »
It'll work that way.  I'm sure you're aware that the carbonation will go down over time once you tap it unless you have a special tap.  I could sell you the special tap; haven't used it in years; it runs on CO2 cartridges.

General Homebrew Discussion / Re: Starsan question... bear with me
« on: March 17, 2016, 02:59:39 PM »
Only properly diluted starsan is no rinse!

I reuse starsan for a long time.  I check that the pH is below 3 if it seems that it has been a long time since I made some fresh starsan.  I don't go by cloudiness as there is enough hardness in my tap water to make properly diluted starsan go cloudy without rinsing anything.
