weggl Posted December 13, 2011 Share Posted December 13, 2011 Am thinking of doing a 2.5Kg of LDME brew and using Cascade as the bettering hop with Motueka for flavour. Am wondering 1f 25g of Cascade for 1/2 hour would be ok? And say 40g of Motueka dry? Any suggestions? Warren Link to comment Share on other sites More sharing options...
Hairy Posted December 13, 2011 Share Posted December 13, 2011 Its probably OK if you like beers with low bitterness. Without doing proper calculations, I reckon the IBU will be around 15. Try using IanH's spreadsheet from AHB to give you a better idea. If that is what you were after then it is fine. If I was making it I would up the quantity a little.

Guest Posted December 13, 2011 Share Posted December 13, 2011 Bettering hop????.... no comment [rightful] How many litres are you planning to make Warren and what AA% are the Cascade? If 23L then 25g Cascade with AA% 7.8 will give you about 16.5 IBU. Personally I'd either do a full 60 minute boil to get 21.3 IBU or if you only want 30 min boil then I'd up the hops to 30g to get about 25.6 IBU.

weggl Posted December 14, 2011 Author Share Posted December 14, 2011 Thanks fellers, Dont understand this IBU stuff APA has a bitterness of 340 IBU,so Bill what is 25.5 IBU? Is the 340 rely 34.0? Howstat, Muddy? Link to comment Share on other sites More sharing options...

Guest Posted December 14, 2011 Share Posted December 14, 2011 I think this is the latest version, unsure as I now use brewmate but FWIW HERE IS THE LINK to ianh's spreadsheet recipe designer. 340IBU's is probably (guess) what it is in the can... there is no freakin way that the APA is 34 IBUs @ 23lt Have a playe with the spreadsheet, it took me a while to understand the numbers I was getting but it is a good way to get a feel for IBU's Yob Link to comment Share on other sites More sharing options...
Hairy Posted December 14, 2011 Share Posted December 14, 2011 Warren, 340 IBU is the concentrated bitterness for the kit. PB2 will correct me if I am wrong but I calculate it like this: Kit IBU x weight / volume Therefore, the APA in 23 litres would be: 340 x 1.7 / 23 = 25 IBU Apparently some bitterness is lost during fermentation so it will finish a bit less than that. It gives you something to work with though. Link to comment Share on other sites More sharing options...
PB2 Posted December 14, 2011 Share Posted December 14, 2011 Apparently some bitterness is lost during fermentation so it will finish a bit less than that. It gives you something to work with though. Yes, anything from 10% to 30% of bitterness is lost during fermentation. Some colour, although relatively insignificant, is lost too. Link to comment Share on other sites More sharing options...

Guest Posted December 14, 2011 Share Posted December 14, 2011 cheers Bill...I havnt used that one for a while now and tend to, when doing kits and extract.. JUST HAVE AT IT but it is an excellent tool for getting to know how much of what hop at what time in the boil affects bitterness by how much... after a while you can sort of get a gut feel for it and just whack em in at what you reckon is a good thing... take notes though of course [rightful] you dont want to (as Ive done many times now) make a corker and have no freakin idea what you did [crying] [lol] [innocent] Yob Link to comment Share on other sites More sharing options...
weggl Posted December 14, 2011 Author Share Posted December 14, 2011 Thankyall I tried the spreadsheet works well, but it does not allow for the amount of malt you use. The IBU varies when the water volume is changed but not when the malt content is changed. Does anybody know what the IBU I\\is for Coopers commercial Pale Ale? The Kit calculator gives an ABV% of 4.1% for 23L, 2.5 LME,+ .5 LDME +.2 DEX Wheras the Online Brewing Calculator for the same gives ABV% of 5.6% Big difference[crying] Warren Link to comment Share on other sites More sharing options...
Hairy Posted December 14, 2011 Share Posted December 14, 2011 I haven't got the calculator on hand at the moment but based on the ingredients it would be closer to 5-5.5%. Not sure why it is throwing up 4.1%. The IBU is really just a number and is not affected by the amount of malt. You can have two beers with identical IBU's but one may seem much more bitter than the other. Using a lot of malt may leave some residual sweetness which can mask the bitterness a little. So although the IBU may indicate it is quite bitter, the bitterness is perceived to be less. Its all about perception. Does that make sense? I think I have just confused myself [unsure] Link to comment Share on other sites More sharing options...

As for the IBUs and malt, the spreadsheet assumes you are using a wort of 1040 for your boil. Link to comment Share on other sites More sharing options...
weggl Posted December 18, 2011 Author Share Posted December 18, 2011 The spreadsheet wont be much good for Tony, 1040?[crying] Hairy I think I perceive what you are saying[pinched] Link to comment Share on other sites More sharing options...
