In Brewing Classic Styles Palmer says you can steep specialty grains overnight in cold water, especially if you have a lot of dark grains. Has anyone done this? If you steep them overnight can you skip heating up to 155 degrees and holding for 30 minutes on brew day?
I’ve done this when I’m using a dark roasted grain for color adjustment and want to minimize the flavor contribution. I do find it provides less harshness when using roasted grains.
But the easiest way to approach steeping grains is just to add them to your kettle when you start heating your water, then pull them when it hits about 165F. This works perfectly fine - there’s no need to hold it at a specific temp unless you are doing a partial mash.
I find that I get less color from cold steeping even when I add the malt to the sparge water. I haven’t done enough to cold steeping to figure out how much extra grain I should use to compensate. I may have cold steeped with whole malts rather than ground malt so my experience may simply reflect the grind.
That is up to you to decide. Cold steeping provides a smoother flavor. You can get a smoother flavor by using huskless dark grains like carafa and midnight wheat. However there is no huskless replacement for roasted barley that I’m aware of.
Anyway I’ll continue to do cold extracts for 2nd running beers
Patagonia Malt has a huskless roast barley they call Perla Negra (black pearl barley). I haven’t ever seen it at the local homebrew shop, but if you ask around you might be able to get your hands on a few pounds. Check it out.
