3. 3 yeast looks unsettled and messy and there are volcanoes erupting and CO bubbles shooting up into the tank then the yeast is misbehaving and clarification is being compromised The best thing to do would be to close the tank valve remove the sediment bottle like you do when you first clarify and dump that sediment and rinse the bottle Fill the sediment bottle up with foam from the tap as you do during clarification and put it back on the brewery Make sure the gas cylinder is onto the vessel to maintain pressure as it should be at this stage Then very gently open the valve and let the beer that s in the cone drop into the sediment bottle You might want to do this over a few openings and closings to let it settle without shooting back up into the tank e g 10 little openings and closings with a 10 second break between each opening When the sediment bottle is full open the valve fully and leave that overnight Hopefully it s then clear Usually you ll find you just have some sediment above the valve and it s only a few inches that settles overnight But at least the beer has a chance to settle better without erupting yeast delaying it You hopefully can see the beer line easily and it clears up by this extra day 4 Ifthe beer still isn t clear it may take a 3rd clarification So after performing point 3 above just do a 3rd clarification Fig 53 using 30ml again Make sure the tank valve is closed before you clarif

The bottle should be 2 to 34 full of clarified sediment with a clear beverage layer seen at the top of the bottle See Figure 54 2 Close the vessel valve Unscrew the sediment bottle see Figure 42 It screws off clockwise looking down on the bottle It is under pressure so there will be a small release of pressure as it is unscrewed but it is full of liquid so it will be minimal However it is advisable to unscrew the bottle with one of your hands wrapped around the top part of the bottle to block any small spraying of beverage 3 When you have unscrewed the bottle place it in the stainless steel bowl under the tank see Figure 43 Then take the 500 spray bottle and spray up into the vessel valve to remove beverage residue from the under side of the valve and valve thread see Figure 44 Let the water drip onto the bowl Then using the removable stainless steel bowl under the vessel to prevent dripping onto the floor take the sediment bottle and bowl to a sink Figure 45 and dump the sediment down the drain and rinse the sediment bottle and stainless bowl both well with water 4 Then put the bowl back under the tank For safety reasons we recommend putting the rinsed and empty sediment bottle back onto the brewery but do not open the vessel valve It can stay there empty under the closed valve as a safety device should someone or some child accidently open the vessel valve 6 The vessel temperature is set at 1

10. 8 Litres per 455g of grain or 1 litre per 120g This ratio is suggested to ensure a decent extraction of colours and flavours but to avoid too much extraction of tannins from the grain husks Tannins can give a drying puckering mouth feel 3 We suggest to heat the steeping water to 70 C 158 F and then add the grains The temperature will then drop 5 C 9 F when the grains are added Steeping above 70 C 158 F may result in excess tannin extraction and steeping above 60 C 140 F will ensure a pasteurisation of the grain material to reduce risk of infection so we re targeting 65 C 149 F at the start of steeping once the grains are added 4 fthe amount of grain used is only 115g or less 1 4 then we suggest to use a French Coffee Press with about 1 litres 2 US pints of 70 C 158 F water added as shown for aroma hops in the previous chapter Then use the Standard Method for ingredient addition rather than the method described below It will not have too much effect on the final wort temperature and is simpler 5 The grain must be crushed to extract the flavours and colours and other components Each grain should be crushed into at least 5 parts to optimise extraction Suppliers can crush grain for you or you can set up your own small mill or a similar system 6 Aslong as the grains are strained from the water so no solids are added to the WilliamsWarn which can block the beer tap any soaking and straining metho

C 34 F for clarification so If you d like to increase the temperature now e g to consume at 8 46 for an English Ale then do so now 39 Please be aware that the beer will warm up a couple of degrees as it pours through the line and beer tap so set the temperature slightly lower than what you want it in the glass It will take a few hours to warm up the beer in the tank if you increase the set point now To pour your first beverage hold a glass under the draft tap and close the draft tap flow control lever by pulling it up as far as it goes Then pull the tap towards you and then with one of your fingers open the flow controller slowly by pushing it down to get an optimal flow see Figure 55 If it is the first pour of the day the first 50ml in the line may be warm and promote a little excess foaming in the glass so a slow flow is optimal for the first part of the pour until the cold beverage exits the tap Then you can adjust the flow controller to increase the flow speed and pour a good glass of your own making see Figure 56 When pouring beer before the glass is full push the tap away from you to create some beer foam onto the top of the glass If the beverage is not totally crystal clear don t worry it will keep clearing and in most cases soon be bright It just may just need an extra 1 2 day or so However some yeast need an extra clarification as discussed in Appendix 8 Rinse the draft tap with

The top surface of the foam will retain the positive pressure and not take in air and as the bottle is filled we can displace all air from the bottle Fill the sediment bottle to the very top with foam then close the draft tap and push the draft tap control lever up to its fully closed position see Figure 47 Put the sediment bottle which is now full of foam back on the vessel and close it hand tight as per normal The bottle screws on anti clockwise looking down Keep the vessel valve closed do not open it and move onto the next step Ensure the 3 way valve is closed X position and open the clarification pot Add 30ml of WilliamsWarn clarification agent to the 100 cylinder and then transfer that to the pot through the tea strainer see Figure 48 Then screw the lid back onto the clarification pot tightly It is important to strain our clarification agent through the tea strainer because crystals can form in the clarification agent over time and these can block the one way valve under the pot If the one way valve becomes blocked it will not close and the beverage will blow back up the pressurised line into the pot and out over the brewery All liquids added to the pot should be strained except for water NOTE The next sequence of forcing clarification agent into the beverage is required for first time brewers to use in order to create an exact and known pressure differential and then experience the amount of vigor
58. The cold temperatures also assists the clarification agent to combine not only with yeast to clear beer but also with haze proteins from the barley that make beers hazy The colder the beer the more of a reaction there will be between these proteins and the clarification agent which helps make a brighter beer This is why we recommend cooling any beer to 1 C 34 F for clarification with our clarification agent The dispense temperature can be increased on the controller once clarification is complete if you would prefer to drink the beverage at a warmer temperature MAKING BEER IN FOUR DAYS It is possible to make beer in 4 days in a WilliamsWarn Use our summer Ale as a base and add any extra steeped hops or malt as desired or brew it straight Ferment as usual at 23 C 73 F for 2 days As shown in Chart 1 5 04 is usually finished 2 days Check this is the case by looking at the amount of foam on the surface of the brew During fermentation there will be much foam covering the top surface but once fermentation is finished the foam will only be about 2 5cm 1 inch in diameter If this Is the case you can put the cooling on and perform the first clarification straight away warm before the beer has cooled After 24 hours perform the second clarification cold The brew should then be clear and ready to consume If not give it another day to clear 62 APPENDIX EIGHT BEVERAGE Clarifying the beverage is important
