I used WLP800. I am actually making a Munich Dunkel. It came in higher than expected 1.062. I was using WLP833 in a gallon starter. The starter was still after almost a day at room temp (around 70), so I figured the yeast was bad. I was already brewing at that point, so I got the mash going and ran to my home brew shop (a satellite shop with a stripped down inventory). All they had was WLP800....so, I took the vial they had and pitched it when done.
I am down to about 52 degrees now and fermentation looks good. I plan to bring it down to a little below 50 and leave it there. I will do the rest to hopefully eat up that diacetyl.
I do keg, but have never used them as a secondary. I was transferring to a 5 gallon carboy after fermentation was complete. I will have to think about just using the kegs.
My barrel came from one of my local breweries here in Florida. There is a small 2-person outfit in Central Florida making whiskey. They have been selling them to the brewer here, so I just asked him to get me one. I don't know where you are, but check witha local brewer there if you have any breweries around. They will probably have a line on one.
