I know it has been asked before but what is the best mash time for a 3kg partial for my Bock, 60 or 90 min's?
I thought longer mashes tend to be used with less modified malts and those with low enzymatic power, like the ones in my bock, ie. carapils & vienna.

Also what is the be grain/water ratio? i was going to work on 1 part grain to 2.5 parts water.
A Bock without Munich malt? :eek:

I'd be going for 90 minutes with the Vienna, the Carapils just requires steeping but it is okay to mash it.

Good luck


BTW, I'd give this recipe a go if you are partial mashing. I made it a few years ago and it was fantastic!
That is the one i walked into my HBS to buy but he was out of Munich so we went with 1kg Vienna, and we used 1kg Carapils instead of Pale 2 row malt and added 200g of Wheat malt. + the
300g Caramunich
200g choc malt
3kgs of Black rock "AMBER"
25g Northern Brewer
30g Hallertaue
and the ol S-23 Saflager

IMHO i would go with 2.5ltrs per kg of grain for the mash.
Sparge with hot water - same volume as you mash for the boil.

Then fill up with cold water mix up and leave until you are ready to add to the fermenter upyo the 23ltr mark.
I thought that was the case fellas, thanks.
Also is there a list of what grains are base malts that need mashing, and grains that need steeping? As i thought Wheat Malt, Vienna & Carapils needed mashing?
I agree with Ken - 1kg to 2.5L. That is a good mix - not too loose, but loose enough to spread the enzymes around. I would sparge with 80C water. With 3kg of grain, you would need to have your sparge water at near boiling to get an 80C sparge temp. As for mash time, I think you would be fine with 1 hour. Vienna generally has enough enzymes to self convert in 30 mins or so, so 1 hour should be heaps.

An hour should be heaps

I would preferably mash the carapils--not all brands of it are steepable

The original recipe calls for 1kg 2 row pale malt. My mistake, but i changed that to carapils as the HDS bloke had no Pale malt. With the lack of enzymes in the Carapils and the fact that it is a crystal not a base malt, i am a bit worried about the mash.
But if i do a 90min mash will that help in the conversion?
it reckon mended to use only 5 % of carapils in anormal beer or 40% if ur doing a light beer
why not mash everythin, you have to mash the vienna anyway. As for how long i use to mash for 90mins all the time, but these days i only mash for 60 and have not noticed a difference in my effieciency
oh yeah, i always mash 3:1. ie litres:kg
Should i add some pale base malt to the 1kg carapils & 1kg Vienna to add some diastatic power ? i would think i can't hurt, would it make it more of a Dopplebock?
