Quick Sparging Queston

[ni9e]

I have seen some posts mentioning Batch Sparging and I would like some help understanding the technique.

After the mash do you run all the wort out of the MT then refill with x amount of liters of higher temp water until you have the required volume of wort?

If so do you give the grains a good stir and how long do you need to leave the grains to settle and I take it you return the runnings back till the wort runs clear.

Thanks

Yes, make sure the water is of the correct temperature to get the grain bed + sparge water to 170°F

Not sure about the time to leave it, but you will need to do another vorlauf to get the runnings clear again.

Do a google search for batch sparging. There's a ton of information on it.

At the end of the mash I add my first addition, stir & let settle for 10 mins then recirc. & run-off.

I then add my second addition, stir & leave for another 10 mins, recirc. & run-off again.

Done & done (and I mean done)

Cheers guys is there any benifit over fly/batch sparging or it it down to prefference?

There is less risk of over-sparging (extracting unwanted tanins) Also saves alot of time and the task of having to sort out decent sparging equipment and technique.

I sparged my first AG but subsequent brews after that have all been batch sparging as I just find it easier as a beginner. Guess it depends on how you want to brew really; I wouldnt overule sparging in the future.

You can get better efficiencies from fly sparging (about 5% difference seems to be the average). I also find fly sparging easier as I just set the inflow and outflow rates on the taps, watch it for the first few minutes to check it's about right, then leave it for about 45 mins to sparge. I'll normally check halfway through.

Batch sparged my first A.G last Sunday.Seemed simple enough,though time consuming.
68.96%, so am happy with that and will stick with it .

I've been fly sparging via a watering can and it seems to be working for me I think I need to work out my efficiency and try both to see which is better

Help an idiot please? What is the (in simple terms) the equation on which the efficiency is based?

[PMH0810]

Sounds fair - thank you

Calculate the total potential extract figures using the volume you ended up with.

(wt x potential extract or yield)/brew length

eg

4 kg of pale malt in 23L = 52.17

do the same for all grains and add them up and compare with what you actually got, for eg you may have ended up with 1045

compare the 2 as a percentage

45/52 x 100 = 86.5%

there are some potential extract figures here... http://www.jimsbeerkit.co.uk/recipe_formulation.htm

I'm still a bit green on the efficiency business, do you count all the grains?
i.e Torrified wheat, Flaked barley Choc malt, Black malt, Roast malt...etc, etc.

On the link there is no potential extract for roast, black and choc.
