    Batch Sparging On A Bigger System

    Hi all, I have a 150L system that I do the odd batch on. Currently I fly sparge but I was thinking of going to batch sparging instead. I think I remember reading something somewhere about batch sparging not being as effective (in terms of efficiency) on bigger systems. Does anybody know...

    %aa Of 07 Southern Cross Pellets?

    Hi all, Can anybody tell me what the % alpha acid was for 07 Southern Cross pellets? Its rubbed off the packet I have, and when you're dealing with %aa in this range I think it pays to know exactly what it is! I know the 07 flowers were 16%ish. I have seen one recipe that quotes the pellets as...

    Caramelising First Runnings

    Hi all, Recently I tried caramelising wort in a beer that was meant to be a modern replication of a post WWII ale where only the simplest and most readily available ingredients were used. I used 100% JW ale and all fuggles hops. The idea of the caramelisation was to try and get some caramel...

    Using Wet Vs Dry Hop Flowers

    I recently picked a bunch of home grown hops. I have a vacuum sealer so I decided to vacuum seal them instead of dry them. I have heard that there is no difference between using dry and wet hop flowers. Is this true? I'll be bittering with some super alpha pellets so all the home-grown hops...

    What Has More Grunt... 3-ring Burner Or 2400w Element?

    Hi all, I was wondering if I could call on the advice of some of the more technically-minded brewers out there... I know some of you have some pretty funky formulas etc for calculating the time it takes to heat certain volumes of water with certain burners and elements. I am tossing up whether...

    3-ring Burner Natural Gas Conversion

    Hi all, This morning I had mains gas installed into my brewery. I also had a hot water tap put in just next to my HLT. This has pretty much solved two of the biggest hassles in brewing - refilling LPG gas bottles, and running the hose 10m from the tap to my HLT and then bolting to the tap like...

    Mac's Hoprocker

    Hi all, My uncle brought back a bottle of Mac's Hoprocker from NZ recently. Last night I tried it and I was blown away! Great beer. They call it a pilsner which is a bit of a stretch (Nelson Sauvin and Cascade hops!) but all the same its a great hoppy lager. Not sure how much Nelson Sauvin is...

    Force Carbonating A 9l Keg

    To date I have only force carbonated 18L kegs. I find that 200kpa for 36 hours gets me the carbonation level I am after. I will be needing to carbonate a 9L keg in the next few days and I was just wondering if the process is any different? I assume it will take less (either time or pressure) to...

    Aussie Saaz And Czech Saaz... Differences?

    Hi all, The other day I got some Aussie Saaz hops from my HBS. I've never seen these around before and I'm really keen to try them. I'm planning on doing a 100% bohemian pils with them in the next few weeks. From what I hear they are the exact same plant as the Czech variety, but they look...

    Home Grown Hops: Identifying An Unknown Variety

    Hi all, I was lucky enough to have a fellow brewer give me some rhizomes last year and they are now growing like crazy. The only problem is one of my sister's kids kindly yanked out some of the stakes I had in the pots with the hop varieties labelled on them! :angry: So now I have two...

    Plate Chillers

    Hi all, I must say that even though I am now a "no-chiller" convert, I have always liked the look of plate chillers. But then I always get nervous when I hear stories about them getting clogged with hop debris and break material, thereby increasing the chance of infection. I gather quite a few...

    Pitching Onto A Yeast Cake More Than Once

    So, everybody says, "don't leave a beer sitting in the primary fermenter for longer than 2-3 weeks" because you may subject yourself to autolysis. For my last lager, I couldn't bring myself to throw out all that nice yeast sludge (Saflager 34/70), only to brew another lager and have to pitch 2...

    Hlt Advice

    Hi. I currently use an old 18L urn for my hlt. I don't know why its called an 18L urn because only around 15L of water fits in. Anyway, I am starting to brew double batches now and so I consistently need more than the urn's capacity in both mash water and sparge water. I am getting by at the...

    Fermenting In Oak

    I have a family background in the wine industry and often see things that make me think "hmm, I wonder if you could do that in brewing too..." We ferment quite a bit of our wine in oak, as opposed to s/s fermenters. I tried a chardonnay last weekend that had been fermented in oak and had been...

    Can A Nasa Boil 200l Of Wort?

    Hi people, Just wondering, does anybody think a NASA burner will be able to boil 200 litres of wort? I know there are a few people around here with mathematical formulas to figure out this kind of thing but my brain was not made for physics... I would guess that since it takes only ~15 mins...

    Clone Brews Book

    Hi, The other day I receiced "Clone Brews" by Tess Szamatulski and Mark Szamatulski from Amazon. I was keen to have a look as there are quite a few beers there that I really like in it - Sam Adams Boston Lager, Bass Ale, Pilsner Urquell, Sierra Navada PA etc etc. But when I read most of these...

    Aussie Nugget Hops

    Hi everyone, Well, I will soon have a mother load of Aussie Nugget hop flowers to play with (from the bulk buy). I am also planning on planting some Nugget rhizomes this year. I am a bit confused on what these hops are actually like though. American sources say they are similar to Chinook or...

    Hop Rhizome Wholesalers

    Sorry to add yet another hop rhizome thread (seems to be a bit of a buzz topic area at the moment!), but just a quick question here... My family is in the wine industry and we have a few vineyards etc. The other day my old man suggested we plant a few rows of hops (yes, that's quite a bit I...

    Hydrometer Increments

    Hi people, I've wondered about this for a while - exactly which line on the hydrometer scale corresponds to the number? Bit hard to explain in words, but the pic below should help. Which line corresponds 1.020 - line "a" or line "b"? This may be a very stupid question, but to me there's a case...

    Changing Mill Settings For Different Malts

    I have a Barley Crusher mill which I have only put 3 brews through so far. All of those brews have used Powells Ale as the base malt (I used to use JW malts but always had them crushed by the home brew shop). I have been learning more about roller spacings every brew I have done so far and...
