Hopsteiner Akoya – An answer to climate change?

Technical Support | Agronomist Dr. Alexander Feiner and his team spent seven years cultivating and testing the 99/268 breeding line. In autumn 2019 they decided to launch the new variety officially, naming it Akoya. Akoya’s yield stability and overall resistance most certainly presents the right answer to climate change, opening up new perspectives to both growers and brewers.

New England IPA and the International Bitterness Unit Test

Hopsteiner Newsletter 05/2019 – The International Bitterness Units test, IBU, was developed in the 1960’s to measure the iso-alpha acid concentration in beer. The test is a simple liquid-liquid extraction where 10 ml of beer is extracted with 20 ml of acidified isooctane by shaking the two in a test­tube for 15 minutes.

Bitter fraction(s) in pellets & ethanol extract (TRE new)

The commercial value of hops and hop products is particularly influenced by the content of alpha-acids. the main source of the beer’s bitter taste. In 2015 the additional contribution of hard resins was clearly demonstrated (1). It was shown that at least 20% of the hop derived beer bitter intensity was attributed to hard resins and about 75% to iso-alpha-acids. The whole range of hard resin components is transferred into ethanol extract, therefore only this type of extract can be called “Total Resin Extract” (TRE). Read the complete article here!

Extreme dry hopping

Just when you thought craft brewers couldn’t add any more hops to their beer they do. Some craft brewers feel that dry hopping with 1 to 2 lbs of hops per barrel of beer is not enough and many are adding as much as 4 to 5 lbs if not more. To see what effect this has on the hop acid composition of beer and bitterness, a series of dry hopping experiments were conducted using Cascade hop pellets with assaying 5.7% alpha acids, 5.5% beta acids and 0.23% humulinones. A control beer with assaying 42 ppm iso-alpha acids was dry hopped with 1.0 lbs, 2.0 lbs, 3 lbs, 4 lbs, and 6 lbs of Cascade hop pellets for three days at 16 °C. As the below chart shows, most of the iso-alpha acids are lost with the first two pounds of hops with smaller amounts being lost with pounds 3 thru 6. Due to the high solubility of humulinones, concentrations reach 48 ppm and alpha acid concentrations reached just over 35 ppm with 6 pounds of dry hopping.

Hopsteiner Experimental

Hopsteiner has recently expanded a new experimental variety from their breeding program in Yakima, Washington/USA. Seventy-five percent Cascade in origin, Experimental #09326 was bred in 2008 and is an aroma-type hop that matures mid-to-late season. Its bright, punchy aro-ma has been described as grapefruit and tropical fruit, but brew trials indicate this variety also adds a distinct berry note in ales, making it an exciting hop to watch! Experimental #09326 trials are still un-derway, so stay tuned for updates on this variety.

High IBU beers (40 ppm of isoalpha acids or more) that are heavily dry hopped, with 1 lb of hops per barrel (0,381 kg/hl) or more, can experience significant changes in hop acid composition. When dry hopping high IBU beers, the leaf material of hops or hop pellets absorb and remove significant amounts of isoalpha acids and add significant amounts of low bitter humulinones and very low bitter alpha acids. ...

The Effect of Dry Hopping on Beer pH

Many craft brewers dry hop with as much as 1 to 2 lbs of hops per barrel of beer (approx. 380 g to 760 g per hl respectively). Dry hopping at these high levels causes an increase in beer pH. To investigate this further, several beers with different IBU’s and different starting pH’s were dry hopped with Cascade hop pellets at 0.5, 1.0, and 2.0 lbs/barrel.
