Hey Thom,
The simplest and cheapest way to step into kit and grain type brewing is through "Hot Steeping" a small amout of specialty grain. This would be in addition to your normal Kit and Kilo or Kit and extract brewing process, as the grains are more there to impart particular fresh flavours than to make up your bill of fermentables like they do in All Grain.
Basicaly you just need from about 50-200g of your crushed grain of choice (Crystal Grain is a great all rounder, Chocolate Grain goes well in my Porter, also a fan of the "Cara" grains, CaraPils, CaraMunich, the list goes on...) and steep it in the plunger with boiled water for 20-30 mins, then strain into your fermenter and continue as normal.
Next step up would be a Partial Mash, as suggested above, this is big pot time. And again, as suggested above, there is some great information out there on the web (www.aussiehomebrewer.com and
http://homebrewandbeer.com and their forums are good places to start) so have a good read before you buy or do anything.
I won't go into too much detail, but it's pretty much:
- Bring a big pot (I use a 10 or 20L stockpot) of water (usually 4-10L) to about 70 degrees and pour in your grain
- Keep at 70 degrees for about an hour
- Strain into your kit wort
- Brew as normal
There's a little more to it than that, but not much. I say do it mate, I've found it greatly improves the quality and range of flavours I can make with my HB.
Oh and once you've given a partial mash a go, and if you're interested in taking the leap to All Grain, I suggest logging on to the forums at
www.aussiehomebrewer.com and investigating the Brew in a Bag (BIAB) method. A nice way to get started in AG without the massive expense of setting up a full AG system.
I hope this helps,
Happy Brewing,
Bear
