I’ve been working to understand my various volume measurements throughout brew day and wonder how Trub and other material is handled. For instance, from my batch sparging I have an idea how much grain absorption and MLT losses to expect, but I know when I do a pre-boil volume measurement there is a fair amount of material in there that is going to add to the measurement.

Also, when doing a, lets say, 5g recipe I assume the is the amount of wort into the fermenter. Is this correct? I know that the amount of trub carried into the fermenter various by beer and beer maker so how does one account for the variations?

Trub impacts to volume measurements and calculations

Currently I gravity feed my immersion chiller. I’ve used a pump in the past, but from what I’ve discovered it isn’t the rate of water that is effecting the rate at which i can chill the beer (gravity is just fine) it is the amount of wort that comes in contact with the beer. So to help things along I’ve been stirring with a spoon. I’m working on adding a pump into my brewing setup to make life easier on me, but I’m not too sure how to go about priming the pump. I plan to have a simple inlet and outlet pipes with 90 bends to push the water around and through the coils of the chiller. I’m not going for a whirlpool affect, at least for now, with my wimpy pump but am just trying to move the wort around the coils without me stirring. For the record i have a valve on my kettle, but I don’t want to use that as I have a filter around it that I want to keep clear until I transfer to the primary. . Anybody have any suggestions of how to go about priming my setup? I know adding another valve would solve my problem, but I’m looking for other ideas as I’m not too keen on this idea as I want this idea to work with several other kettles. Thanks.

I’ve been looking around for differences between the plastic and stainless heads on the chugger pumps. Of course most people say go with the stainless, but I’ve yet to see any rational for it other than fear that the plastic might break (haven’t seen anyone actually report one breaking).

I’m looking to hear from those that have plastic heads or have converted from plastic to stainless what their experiences are.

I’ve used gelatin in a secondary and have been able to bottle condition just fine. I’m working on making a Kolsch and want to see how clear I can get this to be. Any experiences or thoughts on cold crashing and using gelatin in the primary and repeating it again the same steps later in the secondary?

Double gelatin – primary and secondary

Beer Name: Whenever Wit

Style:  Belgian Witbier

Alcohol: 4.31%

Color: 15

Recipe Source:  Midwest Belgian Witbier

This came out to be a pretty nice beer.  I didn’t do anything fancy (no secondary, no fining agents) and was pretty happy with the result.  I added a bit of fresh orange peel to give it a bit more zest though I’m not sure how much it added over the dried peel that came with the kit.  It has a nice hazy color and is well carbonated (if not too much).  If I were to do this again I’d reduce the coriander a bit as it is a bit strong for my tastes, but not so much that it ruins the beer.

My Brew Notes

Ingredients

  • 6 lbs wheat LME
  • 8 oz Carapils (30 min steep)
  • 1 oz Liberty hops (60 min)
  • 1 oz bitter orange peel (10 min)
  • 1 oz coriander (10 min)
  • 1oz sweet orange peel (10 min) added by me
  • 1 oz Hallertau (2 min)
  • Yeast: White Labs WLP400

Execution Notes

I didn’t do anything fancy for this beer and left it in the primary untouched the whole fermenting time (and a bit longer).

I did a bit more research of Witbiers and came across this post which suggests fresh orange peel.  So I added a bit of my own to the kit.

For what it's worth, Here's a quote from July/Aug 2007 BYO mag, Style profile (Witbier) by Jamil Zainasheff:

"The best way to add citrus character is with fresh citrus. The Petrified bits of orange peel often used may be authentic, but fres zest has a much brighter character. Select tangerines or oranges with a nice bold, fresh, aroma...Use a citrus zester to peel the very surface of the skin and avoid digging deep into the white pith as it is bitter and lacks citrus character. Measure the zest by weight, targeting about 1 to 2 ounces in a 5 gallon batch."

His recipe is in that article, as well. (calls for 1.5 oz of zest and .4 oz of crushed coriander.)

So I didn’t do the yeast start calculations correctly and subtracted 5 months instead of 4. This resulted with an over pitch but given that I hit my OG and FG right on everything worked out just fine.

Also, I didn’t clean out my tubing right away on brew day.   Some of the hoses look stained now.  I’m not sure if they would have been if I’d cleaned everything right away, but I think they are still usable.

Finally, my fermentation could get down to cold crashing temperatures.  At one time it was iced over so I had to let the thaw out.  This was the first time it has ever iced up and after that either something broke in the A/C unit or just I’ve never tried to cold crash when it was this warm.  Either way my fermentation chamber could only get down to ~55 degF and that was with it running almost none stop.  I really hope it didn’t break.

Recommendations for next time

Use less coriander.  This beer is a bit too spicy for my tastes. Still good, but I’d tone it down a bit as suggested in the same Witbier article mentioned above

For what it's worth, Here's a quote from July/Aug 2007 BYO mag, Style profile (Witbier) by Jamil Zainasheff:

As for the coriander, he says, "I gently crush the coriander with the back of a heavy spoon to expose the inside of the seeds, which gives it a fairly strong, spicy character versus whole seeds. The level of coriander is probably the area most brewers overshoot, resulting in a really peppery beer. The desired result is a gentle background spicing not an overwhelming one. If you have fairly fresh coriander, start with .4 oz per 5 gallon batch during the last 5min of boil."
