I based the recipe on Jamil’s Munich Helles recipe and made some tweaks to it. What I loved about brewing a lager is how simple they can be…one type of hop, simple malt grist and more involved yeast and fermenting schedule.
I fermented this at 10.5°c until 70% attenuation. Then slowly increased for a diacetyl rest until FG was hit then crashed cooled for a few days. Then I lagered in corny kegs until ready to drink.
