Growing Hops: Time for Beer

|
Pretty on the vine. Think of a caption later.

Roll plump hops between your fingers, then take a sniff. They smell wonderful.

“Fresh from the vine” is not a phrase usually associated with home-brewed beer. But grow your own hops, and you can claim just that.

In the garden, hops are fast-growing, perennial vines that can soar 20 feet tall in a flash. They’re also exceedingly deciduous, dying to the ground and vanishing each winter.

But in late summer or early fall, their female, cone-shaped flowers grow plump with lupulin — yellow, pollen-like granules — that preserve and add aroma and flavor to beer. The lime-green cones look similar to ornamental oregano and are quite pretty, even if you never harvest them.

Because beer-making is a year-round industry and fresh hops are available only during a slim window, brewers most often use bales of compressed, dried hops. But with craft beer enjoying immense popularity, some artisanal brewers have begun creating specialty “harvest” beers with wet or fresh hops.

Typically, wet hops go straight from the field to a brewpot within 24 hours, while fresh hops are dried, then used within a week. Either way, the idea is to capture clean, bright, grassy or floral aromas. Locally, the sweet spot for picking is August or early September. Further north, into Oregon and Washington, harvests may be as late as October.

Getting Started

Hops need at least six to eight hours of direct sunlight a day.

They also need very tall structures to support their exuberant growth. Commercial growers construct elaborate networks of cables for the vines to clamber. In Buellton, Bob and Colt Blokdyk at Windmill Nursery grow Cascade and Nugget hops on their suitably convenient, landmark windmill.

However at home, heavy-duty twine attached to a south-facing chimney or flat, two-story wall will do.

Or use poles. In my garden, I pounded 12-foot-tall, round tree stakes 2 feet into the ground this past spring, to support new plantings of Cascade, Centennial, Liberty and Nugget hops. If all goes well, I’ll add extensions next year.

In addition, hops like loose, fertile soil. My garden sports heavy clay, so I dug holes 2 feet wide and 18 inches deep, worked in 6 inches of compost to improve the drainage and provide plenty of readily available nutrients, then mounded the mix so that each of my rhizomes had its own mini raised bed.

I finished by shaping basins around each, then began watering daily, as hops prefer consistent moisture, especially early on.

Hops vines twist clockwise as they climb.

Ongoing Care

The first sprouts appear like wild, rambling berries, with each leaf a dark green, pleated and rounded at the base and pointed at the tip.

Then fairly quickly, the elongating stems exhibit twisting, twining characteristics, and up and out they go.

Once the stems are about a foot long, select the strongest two or three and use stretchy green garden tape to attach them to their supports, wrapping them in the clockwise pattern that they’re programmed to grow.

Snip off any remaining sprouts to encourage the plants to put all their energy into just a few vines, rather than many.

As the vines grow broader and taller, they’ll begin to shade their own roots and you can taper off watering. Just don’t let the soil dry out completely.

An inch or two of organic mulch will retain moisture longer.

Harvest & Beyond

Several weeks after the cones form, start checking the lupulin glands, which are hidden at the base of each overlapping scale. When the glands begin to swell and produce a strong fragrance, it’s time to harvest. To make sure, roll a few cones between your fingers to see if they release the powdery yellow lupulin along with an intense aroma. The cones should feel a little dry, make a slight rustle in the breeze and may even be turning light brown at their tips.

pretty is as pretty does

Almost — but not quite — ready for harvest.

Ideally, you should harvest individual hops as they ripen. But given that they’re intertwined with trailing stems and leaves that are busy scaling trellises or poles that are 15 to 20 feet tall, that may be rather impractical. Instead, yank down the vines and snip off the hops by hand. Chop up the stems and leaves, then toss them in a compost pile or use them as mulch.

Don’t get discouraged if your vines produce only a few dozen cones the first year. Yield will pick up the second year. By the third year, you should see peak production.

Add wet hops within moments of harvest to a batch of home brew that you’re already started. Or dry the hops for later use. Air drying is easy enough. Spread a layer of hops up to 6 inches thick on a window screen. Place it in a shady spot, out of the sun.

Fluff the hops daily to tease out the moisture. Once the cones are dry — which should take a week or two — pack them into heavy plastic storage bags. Store the bags in your freezer.

In early spring, just before your hops break dormancy, pull away the soil from their crowns and cut off any advancing roots or runners. Also continue to limit each plant to two or three vines when they sprout.

Do this faithfully every year. Otherwise, as your hops gain vigor, they may engulf your garden. Then add fresh compost to the soil mix and fresh mulch on top, and check that your trellising system is sturdy enough for another year.

Although the first year’s growth may appear puny, mature plants bearing ripe hops can weigh 20 pounds or more, which can easily snap thin twine or topple skinny poles. Mature plants also bear the equivalent of up to two pounds of dried hops. Just a few plants should produce enough to brew several very nice batches of beer. Cheers!

Seeds of Wisdom: Other Uses and a Warning

Fall 2013

Fall 2013

Aside from making beer, hops are a traditional herbal remedy and have been used for centuries as a sleeping aid and to treat restlessness. You can stuff a pillow with dried cones or brew a teaspoon or two of crushed hops for tea. Some folks even eat the fresh, spring sprouts like asparagus, which is an interesting approach to controlling the number of vines per plant.

But also note that handling the hairy vines can cause dermatitis, so you might wear gloves. Worse, hops are toxic to dogs and in certain cases have proved fatal.

  1. Very interesting article, Joan, and I will pass it on to our neighbor across the street who makes his own beer! I was seriously considering growing some vines in our own garden, until I got to the very end of the article — can’t have anything toxic to dogs! She eats our figs when they drop off the tree, and has been known to have a bite or two of our apples, so this would definitely be a bad idea for our yard. Hopefully our neighbor will be able to use it!

    • Thanks, D’Ann. Sorry you can’t grow them. But maybe your neighbor will, and then you can do a trade — some of your delicious, vine-ripened tomatoes for his fragrant hops!

    • Thanks, Kim. Also suggest to him to check out some of the online forums on how to build the trellises. I’m sure he’ll come up with an amazing engineering feat.

  2. Do you know where I can buy hops plants in the Santa Barbara area? I would like to support local growers, but so far every shop I have checked does not carry them and cannot order.

    • Hi Brian,
      Try Windmill Nursery in Buellton. That’s where I bought mine several years ago, and they had an excellent selection.
      Good luck!
      Joan
