But still...you can achieve much higher ABV's with this technique than you could ever hope to reach with just fermentation. Not that this should be the "be-all-and-end-all" of homebrewing, but it's another technique to explore, and it can make something pretty unique and almost brandy-like...the braggot I referenced earlier was concentrated three-fold (three 22 oz bombers into one by volume), so I had estimated the final ABV to be around 30% (the original braggot was 11%)...it was a fairly nice sip and savor type of drink...
This thread has inspired me to take a couple bottles from the next batch I bottle (probably my cyser from last fall) and jack me up some mead...
