Santee-based Twisted Manzanita Ales and Spirits, which celebrates its fourth anniversary this year, is seeking investors to help fund a planned expansion of its distribution both domestically and internationally.

The company sent out a missive notifying fans they can buy into the fast-growing brewery in a planned equity issue with shares going for $37, and a minimum purchase of 100 shares or $3,700.

Owner and CEO Jeff Trevaskis didn’t say how much equity he’s giving up.

Twisted Manzanita sold 2,600 barrels of craft beer last year, good enough for 12th highest among the county’s 83 breweries.
