No, that was after my stint out there in’94. I know the system you speak of though. Great idea, until as you pointed out, an unsuspecting critter flies through the focused sunlight. Sorta like honkers with bad timing flying through wind turbines. That’s usually bad for bird and turbine alike.
Diacetyl is more like buttered popcorn or butterscotch. Sulfur is pretty typical with lager yeasts during fermentation but wouldn't be lessened in the final product by a diacetyl rest (if I remember my John Palmer correctly
)
94? I guess I have lost track of the years. I havent lived in so cal since about '88 and remember it well. I am thinking it may have been removed by '94 as the last time I went through it was gone.?????
Had to ask Mr. Google. Solar one ran from 1982 to 1986 and had Solar two following it.
switch the connectors and blow CO2 through the liquid side to clear
Looking closer at your picture. Looks like you are venting in some liquid, star san maybe. What I do is stick the spunding valve on the keg. Set it lower than the transfer pressure and seal the keg at the same time. Saves a little CO2 anyway
