All Grain Brewing / Thermal mass question
« on: December 22, 2013, 08:51:02 AM »
A typical batch uses roughly 11 gallons. Is it any more or less efficient to heat the entire amount of water at once, versus doing in batches (strike water, infusions mash out).

My name is Greg. I live in Bowie/Davidsonville. I recently came into a pallet of 12 oz. Brown bottles from a brewery. I have about 120 cases available to anyone interested. Cost is $5.00/case. Homebrew supply shops are selling for 3 times that much.This is an excellent opportunity to stock up on brand new bottles at a great price.
I can do cash check PayPal or a credit card (2.75% additional).

Other Fermentables / Can't get cider to sparkle

Made with "apple juice from concentrate".  forced 35 psi at 42 degrees. Very hard to dispense and no bubbles. Do I need to add minerals to give the bubbles something to hold onto?

All Grain Brewing / Grain absorption
« on: December 01, 2013, 01:41:07 PM »
I was wondering what factors should be considered when determining a grain absorption rate. Is there any significant difference in wheat versus barley? If you are brewing 10 gallons of pale ale or 10 gallons hefeweizen, any noticeable difference in water needed? Is this something to consider when it's on a commercial scale (50-100bbl)?

Equipment and Software / Does wort evaporate slower than water?
« on: December 01, 2013, 12:03:32 PM »
Trying to get an accurate evaporation percentage for the system settings in Pro Mash. I am also making adjustments to my RIMS PID. Since i just wanted to run water through system, would i get different results than the same volume of say 1.060? Does water boil off faster than wort? And does Wort heat up faster/slower than water with the same heat being applied.
Is the difference to minuscule to even worry about? Thanks.

« on: August 27, 2013, 05:12:38 AM »
It just started fermenting, but in 4 days i am going on vacation for 2 weeks. since i cant be here to do a D-rest, what should I set my temp at? I started at 48 and was gonna bring up to 50 tonight. Can I still do a DR after 2 weeks? Dang, I wish there was a temperature controller app for smart phone.
Oh yeah, it's Wyeast 2278.

Yeast and Fermentation / dark colored starter
« on: August 15, 2013, 04:43:53 AM »
i made a 3 liter starter yesterday using 9 oz DME. when i added it to the water it turned a gray color. After boiling i let it cool and it's very dark brown almost black. i used extra pale DME. what causes this?

Yeast and Fermentation / Smack or dont smack?
« on: August 09, 2013, 05:53:02 AM »
I'm making a starter this weekend using 2 packages Wyeast czech pils. i read somewhere the yeast is actually in the liquid, not in the blister. Was wondering if i should: a) just dump the liquid in my starter, b) smack, mix and then dump in, or c) smack, wait to swell and then pitch to my starter?

Yeast and Fermentation / Exploding bottles, what the heck?
« on: July 29, 2013, 05:30:22 AM »
I bottled some porter last April in swing tops. Had one the other week and seemed over carbonated. Last night I was cleaning and heard a pop; knew exactly what it was. These are pretty heave glass too.
I have had this happen to several beers I cellar for long periods. The yeast I used was a dry fermentis I can't remember the type, just that it was in a light green packet. And I know it didn't flocculate very well.
So what do you think is going on? Usually I FC! But this one I think was bottle conditioned. Too much priming? Or is it there's still some fermentation going on? I have a dry stout that was FC'd, tastes fine except it is now overcarbed has that co2 taste. Is it just some beers need to be consumed faster?

I have a false bottom for my kettle. I was wondering about using it throuchout the boil, then when i pump out it would be in place as a hop back. Would this cause any problems with the boil?

Equipment and Software / Wort transfer to BK pumping question
« on: July 26, 2013, 05:20:14 AM »
I have a March pump for transferring my wort around but in the summer months i like to do my boils outside. the pump is situated alongside my RIMS just a couple inches off the basement floor. I live in a split foyer and want to run a hose from the pump, outside to a kettle, the bottom of which is about 4' above the pump. I was thinking about hooking the hose to the QD/valve on the bottom of the kettle and pumping the wort up into the kettle. my concern is whether the pump can handle 8-10 gallons of pressure in it as the kettle fills. Any fluid dynamics folks know if this will work ok?
