Hops or "Humulus lupulus" is the Jenna Jameson in the orgy of ingredients that goes into the creation of every beer. With all the different styles, the plethora of available extracts and the variation in how they can be used there is no ambiguity to why this one ingredient has commanded such a cult following of "hop heads" in the brewing industry. The names IPA, Double IPA and Imperial IPA have pretty much become the flagship of the American craft brewing scene and has somewhat turned into a "who's is bigger" contest for brewers. Now, I don't hate an IPA at all and I know that some of you would gladly take an Imperial IPA into the basement closet for some 7 minutes in heaven action, but ask yourself...what do you really know about your bitter lover?
Well for starters, one of the biggest growing regions in the U.S. is in Yakima Valley, WA which hosts an awesome event called the Hop Harvest every year. From what I've heard it is a must go to event where brewers can pick the cones off the vines, get to sample the next years product and of course over enjoy some great beer with brewers from all over the country.
The hop plant is a bine which is cultivated in hop yards mainly between the latitudes 70 to 35 degrees N. I recently met a girl who has purchased land and has already gone through one harvest in Southern California...sorry to be the one to tell you, due to the shorter day length its not going to work unless you put up light polls($$$$). Another problem with going further south is that the winter temperatures aren't cold enough. The plants need it a tit bit nipply because the lower temperature breaks the post-harvest dormancy.
Rub & Sniff to check aroma of a whole hop variety |
Whole Hops (Sierra Nevada is one of the few breweries left using these)
- Perishable, bulky (200lb bails), expensive to store ship
- In homogeneous, making sampling and bitterness hard to control
- Poor utilization of alpha acids
- Special brew house equipment needed (hopback)
Hop Pellets
- The are many types of hop pellets but in general they have better keeping quality due to being sealed in evacuated foil and film bags
- Blending takes place during processing gives a highly uniform product
- Better utilization of alpha acids compared to whole hops because the lupulin glands are ruptured in the hammer milling process
Hop Extracts
- These non reduced extracts are made by removing the alpha acids from pelleted hops by generally using liquid CO2 as the solvent
- One down side is they add no aroma to the beer because it is only the essential oils they are volatile compounds in the finished beer
- Are the most stable form of hop products
- Must be added in the kettle so to change them into iso-alpha acids.
- Very high utilization of the alpha acids
- Extremely uniform products
- Can be made into isomerized hop extracts that can be added directly to the green beer.
- Reduced extracts such as rho, tetra and hexa hop extracts are made to be light stable for companies that want to use clear bottles without "skunking" the beer.
