Rather than do a bunch of experimentation I figured I’d see what you guys have used.
Plan is to make a “grand cru” type beer, ~1.100 OG mostly pils blend with vienna base and some sugar possibly stared with wine yeast then finished in red wine bbls with brett b.
The strain that comes to mind is K1V-1116. Most wine strains do not ferment maltotriose, but K1V-1116 readily metabolizes the trisaccharide. I used it in 1.135 mead that went to 17.5% ABV, so the strain definitely can handle high osmotic pressures and high levels of ethanol.
