Change settings in the menu: > Insert > Header and Footer guide  The attenuation is ensured through a synergetic action between  Endogenous action of the barley beta-amylase  Exogenous added pullulanase and alpha-amylase  The fermentable amino acids are provided by a synergistic action of  Endogenous exo-peptidases  An added protease  Good lautering with a clear wort is provided by a combination of well adjusted mills and  A filtration enzyme system including both beta-glucanase and xylanase components, and  A lipase to ensure the wort clarity Summary of the Ondea ® Pro enzymatic solution for brewing with 100% unmalted barley  The synergies between the enzymes are ensured through  A three temperature step infusion mashing profile  With a pH of Time 54 °C / 30 min 64 °C / min °C / 10 min Temperature Mashing Profile

7 The pullulanase is the key for the attenuation performance of Ondea ® Pro  Starch is degraded by a synergetic action of the added pullulanase and alpha-amylase and the beta-amylase from barley  The key is selection of the pullulanase  The main reason for the good performance of the chosen pullulanase is the temperature profile (stability) which fits the gelatinization temperature of barley well. Lab mashing trials. Ondea Pro is compared with 2 commercial pullulanases at equal dose in enzyme protein. DP 4+ measured by HPLC Comparison of the amount of unfermentable dextrin (DP4+) of 3 pullulanases DoseOndea Pro Pullulanase Commercial pullulanase A Commercial Pullulanase B g EP/T barley Comparison of the temperature activity curves at pH 5 of three pullulanases % of max activity oCoC Unique pullulanase added α-amylase added Barley β-amylase Starch Fermentable sugars glucose maltose

8 The attenuation components provide a typical RDF but with a very high maltose content  Novozymes Ondea ® Pro gives a high maltose concentration  A high RDF is ensured by a low amount of dextrins  Ondea ® Pro at 2 kg/t barley gives around 70% RDF  Maltose dominates the sugar profile Results from lab scale mashing trials Maltose conc in % Sugar profile Glucose 5.0 % Fructose 1.5 % Maltose> 60 % Maltotriose< 15 % Dextrins (DP4+)< 20 % Low glucose level leafs the opportunity to add syrup and still create a “maltose” profile

9 Novozymes Ondea ® Pro ensures processing also at higher gravities; but it takes a dosage adjustment or an extension of the 64°C saccharification rest  High gravity reduces the level of saccharification due to product inhibition of the enzymes  Ensuring the same level of saccharification at higher gravities  Either increase the Ondea ® Pro dosage (demonstrated below), or  Extend the 64°C saccharification rest Fermentable sugars (DP-1,2 and 3) measured after laboratory mashing trials with 2 kg Ondea ® Pro per t barley and increasing gravity The sugar profile is kept constant by increasing the amount of Ondea ® Pro. The increase in enzyme dose is plotted against gravity, defining the dose at gravity 1:5 as 100%

Change settings in the menu: > Insert > Header and Footer guide Different barley qualities requires different enzymes dosages.  For each barley variety there is linear correlation between the enzyme dose and amount of non-fermentable dextrin’s  Different barley varieties do therefore appear as straight lines when then the amount of non-fermentable dextrin’s is plotted against the enzyme dose Laboratory mashing. Different dosages of Ondea ® Pro was applied at standard 2 hours mashing with 45 min saccharification rest. The unfermentable dextrins (DP 4+) were measured by HPLC  Ondea ® Pro has been tested on close to 100 different barley samples collected around the world (as of April 2010)  It works on approx 95% of the tested varieties  The few barley where it fails are not suited for malting  The observed variation in generated FAN is well correlated to the protein content  We observe some variation in needed enzyme dose to reach the target attenuation  The reason for this variation is under investigation  It is not correlated to the beta- amylase content

11 Synergy with barley peptidases provides good yeast performance  Novozymes Ondea ® Pro’s proteolytic component works in synergy with the endogenous enzymes from barley  This is demonstrated by a comparison between the effect of Ondea ® Pro on barley with and without inactivation of the endogenous enzymes. The effect of the synergy with endogenous enzymes is demonstrated by a comparison between a mashes at 50 °C with and without a pre-inactivation of the endogenous proteolytic enzymes by a heat treatment at 75°C for 30 minutes Barley wort needs only 9 mg FAN/l/Plato to secure a good fermentation

Fermentation temperature 12 °C, Yeast strain W34/ % barley wort shows comparable fermentation performance with less FAN The FAN recommendations for malt brews are mg/l (at 12 o P) or mg/l/Plato The FAN from 100% barley wort is lower; ml/l (at 12 o P) or 9-14 mg/l/Plato The barley worts have good fermentability This leads to less unfermented FAN at the end of the fermentation

Change settings in the menu: > Insert > Header and Footer guide  Increasing the barley inclusion in mashing leads to an increased viscosity  This cannot be solved by traditional filtration enzymes  The filtration system in Ondea ® Pro keeps the viscosity low even for 100% barley, th ough a combination of  A beta-glucanase  A viscosity reducing xylanase  The filtration enzyme also ensures a good extract yield  Evaluated by low Extractable Extract in spent grain The filtration and extract component ensures low wort viscosity and high extract yields The wort viscosity from lab scale mashing trials was measured at different barley inclusion levels with and without addition of Novozymes Ondea ® Pro

17 The turbidity reducing component ensures low turbidity and facilitates lautering  Barley wort (without use of the lipase in Ondea ® Pro) has very high turbidity and is very difficult to lauter  The lipase in Ondea ® Pro reduces the turbidity of the wort to well under the guideline of 80 NTU (20 EBC unit)  The lipase releases fatty acids similar to the level found in malt based mashing  Less lipid oxidation products are found in the barley beer, likely because there is a lower level of fatty acid in the beginning of mashing where the LOX is active and oxygen are present The resulting free fatty acids from the lipase action in the mash are at the same level as malt with an similar or lower amount of lipid oxidation product Laboratory mashing. The amount of free fatty acids before lautering was measured by HPLC Lipase added to laboratory mashing. The turbidity was measured after filtration/lautering

18 Barley milling in combination with lauter tun and mash filter  Mashfilter in combination with hammer mill  The fine grist of the hammer mill is preferable for the enzyme system  The wort separation procedure needs no changes. Filtration speed and turbidity showed the same or improved performances when compared with all malt brews.  Lauter tun in combination with roller mill  A barley kernel is less friable, and the endosperm is more closely connected to the husk – compared to malt  Milling barley with the same roller setup used for malt will yield a much more coarse grist composition  The finest possible grist composition is needed  Six and four roller mills are preferable  However, successful industrial trials have been completed with two roller mills  Optimized barley milling showed the following: Optimized barley grist composition BarleyMalt Sieve %(18%) Sieve %(8%) Sieve %(33%) Sieve %(21%) Sieve 52-5%(10%) Bottom8-12%(11%)
