What pH should my sparge water be?
You want the sparge water pH to remain under 6.0, which may require acidification if your tap water is alkaline.
Should I adjust Sparge water pH?
Add Acids but No Salts – Another middle group treats their sparge water only for pH using acid additions, but does not bother with salt additions. Their rationale is that managing the pH during the sparge is important to avoid oversparging, but not that important for maintaining the overall water profile.
Do I need to acidify my sparge water?
Re: sparge water pH Ideally, you want to match the pH of your mash, but if you just want a consistent acid addition, shoot for 5.5. We acidify the sparge water to prevent tannin extraction during the sparge. If you want to increase your efficiency, I might recommend switching to a fly sparge technique.
How much lactic acid do you add to Sparge water?
To lower the pH, add some 88% lactic acid half a millilitres (mL) at a time using a 1mL (1 cc) syringe, wait a minute for the acid to recirculate and mix through the pump, and re-measure. It usually only takes us one or two millilitres at most in 10-13 gallons of sparge water to get down into the 5.6 to 5.8 range.
How much phosphoric acid is in Sparge water?
While the batches were mashing, I collected sparge water and acidified each to pH 6.0 using 2.4 ml of 75% phosphoric and 2.7 ml of 88% lactic acid.
How do you add salt to Sparge water?
With batch sparging, I would just throw the salts on top of the mash, add the sparge water and then stir.
What is batch sparging?
Batch sparging is a way of rinsing the grain bed with water to release all the sugars. A brewer pours “batches” of hot water into their mash tun and then drains the tun. This is a popular and easy way to sparge and a great way to get excellent efficiency without too much equipment.
How much sparge water do I need to batch sparge?
*** Safety factor for first attempt at batch sparging 5 litres. *** Total sparge water needed is about 30 litres [allowing a safety factor]. Actual is about 25 litres.
How long does it take to batch sparge mash?
How to Batch Sparge. 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.
What causes astringency in a continuous sparge?
As a continuous sparge nears the end the pH of the grain bed can rise above the optimum pH of 6 and extract husk chemicals that contribute to astringency and off flavours. Another problem can be a rise in the sparge water temperature with heat applied as the water level drops in your HLT.
What are the disadvantages of continuous sparging?
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.
