Notes

Using a packet of Safale-05 and a packet Danstar Windsor yeast.
Aerated for 35 minute with air pump and 5 micron stone. Pitched both yeast starters into wort. After 4 days the fermentation stopped so did a starter with Mangrove Jack Belgian Ale yeast (1/2 packet) in 1.3 liter starter and pitched into the beer to help finish. At this point I also added the 1.3 pounds of maple syrup. After 4 more days of fermentation the beer finished at 1.022. The final ABV is 12.7%.
