well i just performed an experiement....i poured a glasses worth of beer in a sauce pot and put it in the oven for 45 minutes at 170f....
it was a known beer of OG 1.066, FG of 1.003....Brix for it before the oven 7 or so....brix after then oven 6...and the hydrometer reading after the oven was 1.012....so 45 minutes in the oven took it from a bit over 8% to about 4%......
