I smashed for the first time last week. A 2.5 g batch MO & Argentinian Cascade. More as a way to get a handle on the AC's than anything else.
I can't say anything about it yet, and I don't know that I'd tweak that combo again (unless the AC's surprise me.)
But would I SMaSH another combo? You betcha...it's a great way to get to know your ingredients, and to try out different techniques like decoction and roasting your own grain.
Any of you newer brewers reading this thread, don't be intimated by this, you don;t HAVE to make 5 gallons of it, you could do this in any small batch size, from using a gallon jucg 3/4 of the way full (like the basic brewing guys to) to 2.5 gallon, in a water jug...or even your old MR Beer keg which is gathering dust in the back of the closet.
And extract brewers, you can attempt this too...Some liquid extracts, expecially the lightest lovibond ones are SINGLE MALT as well. Northern Brewer #20053 NB Organic Light Malt Syrup...Or even using XLT DME and a single hop would be an extract alternative. Or a base extract + a couple ounces of steeping grain and a single hop.
William's Brewing even offers Marris Otter LME. MARIS OTTER EXTRACT 8 LBS @ Williams Brewing
It's a great way form everyone to get more control of their process, AND to get a feeling for how ingredients work with each other.
