You know we’re heading into harvest season when local breweries are mixing seasonal crops with craft beer.

Two new seasonal brews will be unveiled this weekend.

Downtown’s Angel City Brewing is up first with the launch of its Avocado Ale at its aptly-titled Avocado Festival on Saturday, which includes a guacamole contest.

Food trucks like Steel City Sandwich and Octopops will also be on hand.

Torrance’s Smog City Brewing has added wild fennel growing in Playa Vista to a 5 percent alcohol by volume Scotch Ale they will tap Sunday dubbed Fennel of Love.

It’s the first of a new series of limited edition beers called the Forager Series that “uses hand harvested fruits and herbs to create unique beers that put a spin on traditional styles.”

Here’s more, from the brewery newsletter:

These flowers are not to be confused with fennel seed or fennel pollen, the flowers impart a subtly sweet anise character into a lightly malted and fruity beer. The result is a subtle licorice and fruity aroma balanced by a smooth crisp and lightly malty beer ending in the perfect amount of roast character thanks to the midnight wheat for added balance.
