On 2/12/2021 – I brewed a 10 gallon batch of Storm Surge Baltic Porter, rated at 9.6% ABV. This beer has a large grain bill, as in expense, almost $70 just for the grains.

Also reused the grains and reboiled for 30 minutes, with whole homegrown hops added to the mash tun, to get a 5 gallon batch of lower ABV beer around 5%, which is a great technique to get more beer, literally for free.
I will post the full recipe details later, but some details:
About the Mash: 90 Minute Mash at 148F, at end of Mash the temp fell to about 142F, so then slowly started reheating to mash-out temp of 165F, an extra 25 minutes.
