The Bruery in Placentia, CA just opened a home brew supply shop called Bruery Provisions. I wandered in there before doing a tasting and the place rocks!
It is very well stocked and the prices were very reasonable (I will be trying their IPA extract kit was about $32). I inquired about their extract kits and they guy told me that they currently have 5-6 available, but they are working with several west coast brewmasters (from places like Green Flash) to put together some killer clone kits.
I proceeded to celebrate by downing several belgian delights from the tasting room. Their beer is excellent!
