Sven Posted August 15, 2011 Share Posted August 15, 2011 G'day all, Bastardised version of Paul's Motueka IPA. 1.7kg Thomas Coopers IPA kit 1kg Light Dry Malt 50g Motueka Hops Made to 21 litres IPA kit yeast I'm brewing in the shed with a heat mat covered by a good (old) sleeping bag and blanket. Normally I only brew lagers in the cooler months. What temperature is the best for fermentation? I'd assume 18 to 22 degrees. When should the Hallertau hops be added? I was thinking 3 days into the ferment but have been told not to add until a day before the end of the ferment. Steve Link to comment Share on other sites More sharing options...
GregT5 Posted August 15, 2011 Share Posted August 15, 2011 Steve, I have just bottled this recipe. I used 40g Pacific Hallertau hop flowers & added them in a chux cloth on day 4. I don't think the hops would impart much flavour or aroma if you added it about a day before ferment has finished unless you were planning to leave it in the FV for a while after to let the yeast clean up after itself. Brew was in the fermenter for 12 days. I brewed mine at 19 degrees. The sample tasted great when I was bottling [biggrin] possibly my best brew yet. Hope this helps. Greg.

Sven Posted August 15, 2011 Author Share Posted August 15, 2011 True that, Greg. It is your suggestion from my Suggestions Please post that I went with first. Merci! Can you throw the hops in as is? I rack to a secondary fermenter anyhoo. Or do I need to have it in a cloth? Link to comment Share on other sites More sharing options...
BrendanS8 Posted August 15, 2011 Share Posted August 15, 2011 Hi Sven, i,m also brewing a motueka IPA at the moment. I use hop pellets and i just chuck em in at about day 4 or 5. Works fine for me[cool] Link to comment Share on other sites More sharing options...
BrendanS8 Posted August 15, 2011 Share Posted August 15, 2011 One question but, should i strain the hops when pouring into the FV or not ? Link to comment Share on other sites More sharing options...
GregT5 Posted August 15, 2011 Share Posted August 15, 2011 I don't rack to a secondary fermenter so I use them in a chux cloth. You may need advice from one of the brewers with more experience than me about what hops do in fermenters when they are chucked in loose. Sorry.

PB2 Posted August 16, 2011 Share Posted August 16, 2011 To avoid the chance of the odd bit of hop debris suspended in the beer, use some form of bag to hold the hops - I use a chux style cloth. During sedimentation, yeast will attach to the hop debris to help draw it out of suspension. How completely, this happens, depends on the flocculation capacity of the yeast.

Sven Posted August 16, 2011 Author Share Posted August 16, 2011 Thanks Paul. As an update, I tried wrapping the fermenter with an old low temp. rated sleeping bag and a blanket and a heat pad under that but it went out to 27 degrees overnight. Got the krausen going though! I've turned off the pad and left the sleeping bag and blanket wrapped around. Will see how that goes. Link to comment Share on other sites More sharing options...
Sven Posted August 16, 2011 Author Share Posted August 16, 2011 I've turned off the pad and left the sleeping bag and blanket wrapped around. Will see how that goes. Well 7 hours after turning off the pad the brew is still 27-28 degrees. The sleeping bag is working TOO well so it has been packed away. The purple blanket is going it alone.

Sven Posted August 17, 2011 Author Share Posted August 17, 2011 Down to 22.3 degrees with the blanket. That'll do pig....that'll do. Link to comment Share on other sites More sharing options...

Guest Posted August 17, 2011 Share Posted August 17, 2011 Don't worry about Muddy Sven, he has been on medication for the past few weeks and it works wonders with his brews. [alien] Link to comment Share on other sites More sharing options...
Sven Posted August 18, 2011 Author Share Posted August 18, 2011 That eBay temp controller can't come quick enough. As you can see I'm struggling to maintain a nice even temp with this s****y weather. Gone from sleeping bak & blanket & pad (too warm), to just the sleeping bag (still too warm), to just a blanket (too cold). Have I stuffed my brew up? I've put the heat pad under the fermenter just now with no insulation and I haven't thrown the hops in yet. Should have stuck to lagers/pilseners in winter!

Hairy Posted August 18, 2011 Share Posted August 18, 2011 You've had some big fluctuations there. From 27 degrees to 14 degrees. It looks like it is almost finished but your yeast may have nodded off to sleep at 14 degrees. You may want to raise the temp again to finish it off. There is only one way to see what impact this has had on your beer and that is to bottle/keg it and taste it. It could be fine or it may have some unexpected flavours. It will probably be drinkable anyway. Link to comment Share on other sites More sharing options...
Guest Posted August 19, 2011 Share Posted August 19, 2011 The 27 degrees maybe a little worry but apart from that there really isn't much worry. I lay odds that it should be fine [rightful] Link to comment Share on other sites More sharing options...
