I see you mentioned a Munich Dunkell CB. That comes up pretty well at low alcohol.
A very easy beer to brew at low alcohol (I have done it as low as 2.5% ABV) is a Schwartzbier.
To brew either of these (and even pale ales) all you have to do is the following...
1. Reduce the original grain bill accordingly.
2. Keep the original hop bill. Do not adjust it from the full-strength recipe.
3. Mash at 70C.
You'll be surprised at how well the above formula works. Very tasty beer! The higher mash temperature adds body etc while retaining the original hop bill balances out the increased 'sweetness' caused by the higher mash temp.
Hashie will have a good Schwartzbier recipe I think. I should modify then post up the Schwartzbier recipe I used in the original BIAB guide. It's a great recipe. Until then, you can get it by downloading the "BIAB Checklist Black Beer.xls" file in Post #1 of this thread.
The Schwartz drinks very well straight away even if brewed as an ale with US-56.
