Measuring custom proportions of hops, malt and wheat, area residents brewed their own beer at Barleycorn's in Natick on Thursday.
Daniel Eng, the owner of Barleycorn's, started the business in 1998 as a way for beer lovers to make their own custom creations.
Eng says his favorite thing about beer is that he can "experiment with spices and different measurements like with cooking."
When it comes to his favorite beer, Eng said he can't pick just one.
"My favorite beer is my next one," Eng said.
