I used two packets of s23 when making a Munich Helles. Fermented at 50F°. After a week, diacetyl rest (raised temp 2F° every 12 hours until reaching 64F°) then let it sit for 5 days. Cold crash to 35F° for a month before carbonation. Turned out great.
Ok. That’s a fairly high attenuating yeast. If you were using wlp002 (English ale yeast, low attenuating 63 - 70%) then maybe that would be the reason for the final gravity.
I brewed a Vienna lager not too long ago using WLP838 (Southern German Lager). It was delicious. I didn’t do a “side by side” comparison but, I would say it’s very close to a Negro Modelo.
Never thought of adding salt to a bucket of ice along with the stainless pre-chiller. It works for homemade ice cream.

From the Rahr website:
Rahr standard 2 row has an SRM of 1.5 - 2.0. They describe their malt as . . . “lighter than most pale ale malts. It has moderate protein levels, and good extract yield.”
I pick up a jar of spicy, pickled quail eggs from a place called Granzella’s off of Hwy 5 in Northern California. The pickled eggs make great garnish for Micheladas!
