Quelle température pour l'eau de sparge?
Indeed, conversations about sparge temperature tend to focus mostly on the negative effects of sparging too warm, namely the extraction of astringency causing tannins, yet relatively little exists about the impact of sparging with cool water. Back in 2009,.

Use this sparge and strike water calculator to determine how much sparge water will be necessary to rinse your mash and get you to the proper pre-boil volume. Out of all our calculators this is hands down the most used. If you constantly brew different beers like us, this calculator is your best friend. Each new batch of beer has different.
A brewer testing the water temperature at the sparge arm during
Heat the water to around 185 °F (85 °C). This will help maintain the grain bed temperature of 168°F-170°F (74°C-76.7°C). Once the first runoff is complete, perform your second batch sparge. Add the water, stir the grain thoroughly, close the mash tun, and let it rest for a few minutes.
The Joule Heating Effect
I agree that sparge technique/temp has nothing to do with OP's attenuation issues. Those could be recipe related, mash temp related, or yeast/fermentation related (underpitch, lack of viability, insufficient aeration at pitch, etc.) Sparge temp has nothing to do with the low efficiency of batch no. 3. Sparge technique may have played a role.
Frost (temperature) Wikipedia
Step 1 - The Mashout. This is when you raise your mash to 170 degrees Fahrenheit or 77 Celcius. The reason for this temperature is that both stops the enzymatic conversion of starches to fermentable sugars, and makes the mash and wort more fluid and thus easier to sparge. To set this up, one pours the heated water into the mash tun.
7. Models Introduction to Climate Science
The fly sparge method is where the hot sparge water (e.g.,170 °F) is very slowly sprinkled above the spent grains. The idea is to maintain about 1 inch of water above the grain bed and complete this process over about 45 - 60 minutes. The equipment used to accomplish this sparge is typically a cooler containing hot sparge water (sometimes.
Fly Sparge Water Temperature Test YouTube
It has drawbacks in two areas, time and over sparging. To continuous sparge a typical mash can take 60 to 90 minutes and during this time you must maintain the temperature of your sparge water in the 75 - 80 Celsius range to remove all converted sugars.

Heat sparge water. While the mash is resting, heat enough water for your sparge to 170°F (76.7°F) in your secondary pot. For this recipe, you'll need about 4.75-5.5 gallons (19-22 qt; 18-21 L) of sparge water to reach the target pre-boil volume. Pre-boil volumes will vary depending on how much wort evaporates during the boil.
Sparge Water Heater 18 L Water heater, Heater, Water heating
Typically, 1.5 times as much water is used for sparging as for mashing (e.g., 8 lbs. malt at 2 qt./lb. = 4 gallon mash, so 6 gallons of sparge water). The temperature of the sparge water is important. The water should be no more than 170°F, as husk tannins become more soluble above this temperature, depending on wort pH.

Sparge Temperatures, Overcarbonation, Frozen Beer, and Brewing Calculations. Q I'm confused. Sparging is supposed to be done with a grain bed at 170 °F (76 °C). A lot of articles say to use sparge water at 170 °F (76 °C). If mashing is at 152 °F (67 °C), the grain temperature will never get up to 170 °F (76 °C). I've been using.
What Temperature Should Your Sparge Water Be?
When it comes to sparge water temperature, the general consensus is to maintain a range between 168-170°F (76-77°C) throughout the wort collection. This temperature contributes to improved lautering, as sugary solutions are less viscous at higher temperatures, allowing for easier separation from the grains.
Le Birre del Giò Nuovo sistema di fly sparge
Your sparge water should be heated so that your grain bed remains at 168-170 °F (76-77 °C). A little over in the early stages of sparging doesn't hurt. In all-grain brewing, after the grains are mashed, the wort is run off to the kettle. To ensure that as much of the sugar is recovered from the grain bed as possible, it is rinsed with.

If the sparge water is also warm, it will certainly liquify not just sugars, however additionally tannins from the grain husks. When sparging is gone over in the homebrewing literary works, the ideal temperature level of sparge water is inevitably offered as 168-- 170 ° F (76-- 77 ° C). If your sparge water is 168-- 170 ° F (76-- 77 ° C) in.

Batch Sparge Temperature; As the volume of the sparge water matters, so does the optimum temperature. In any case, do not let the sparge water temperature go beyond 168-170 F (76-77 C), as husk tanning becomes more soluble beyond this range. Failure to maintain the temperature may lead to astringency in the beer.
Climate maps Vivid Maps
The sparge water temperature is held down only because, as the sparge progresses, the mash temperature will slowly rise to the water temperature. Some brewers begin sparging with very hot water — say 185 °F (85 °C) — to raise the mash temperature quickly. This is an alternative to the mash-out step if you do single-infusion mashes in a.
Sparge water and its temperature for homebrew YouTube
Even when you are attempting to fly sparge, then you need to maintain the temperature of your sparge water throughout the process. It is less of a concern, in my option, if the wort which is already drained from the mash tun loses some heat, but I would definitely want to keep my sparge water within the 168-170°F range as far as possible..
