Barley Wine History Brewing Techniques Recipes – Fal Allen

But these stack condensers, if not properly designed, can also be a deterrent to achieving an adequate boil. If designing a brew kettle, be sure that the heating surfaces of the kettle are properly sized and will not impede boiling or achieving the proper amount of wort evaporation. Hop Bitterness: Extraction and Isomerization Hops give bitterness and flavor to the wort. The bitterness comes from iso-alpha-acids, which are derived in the course of the boil from the alpha acids of the hops.

Alpha acids are not very water soluble and must be boiled in order to isomerize them or make them water (wort) soluble. But the isomerization process is not solely heat dependent; it is enhanced by physical action as well. The maximum conversion of alpha acids to iso- alpha-acids is about 32 to 35%, and is best achieved with an approximately ninety-minute boil. Most homebrewers, incidentally, can expect 20 to 30% hop utilization. Boiling with hops for more than ninety minutes can extract harsh and unpleasant bitterness.

Extended boiling can result in iso-alpha- acids being hydrolyzed to a nonbitter compound called humulinic, thereby lessening their effectiveness. When using longer boil times often associated with the brewing of barley wines, be prepared to hold off on adding your hops until later in the boil. Another consideration when making high-gravity beers is that, as the gravity of the wort being produced increases, the hop utilization will decrease. We therefore suggest adding 1 to 4% more boiling hops into the kettle when brewing a barley wine.

For example, use an additional 1% for a wort of 1.080 SG (20 °Plato) and 4% more for those massive gravities over 1.100 SG (25 °Plato). Kettle pH The kettle wort pH should be between 5.2 to 5.4 because this will favor protein coagulation and keep color formation at a low level. The optimum pH for protein coagulation is 5.2. Also a pH of 5.2 or above favors hop utilization and reduces harsh hop bitterness.

If your kettle pH is too high, try adding gypsum to acidify it. Color Formation Boiling the wort produces an increase in color. The longer the boil, the more caramelization of sugars and the greater the formation of melanoidins, resulting in more color in the finished beer. Extended boils magnify the color representation of pale and specialty malts in particular, demanding the brewer use an even hand in their selection and proportion.
