    Force batch sparging with a bike pump

    It worked - a valve opened ~25% flowed the whole time. Thanks.

    Force batch sparging with a bike pump

    thanks for the advice - I'll try the slow open on the valve. I do have a hose connected to the valve - maybe it is too think and I should look at a thinner inner diameter. This will help keep the tube fully saturated with wort instead of air getting in through the end.

    Force batch sparging with a bike pump

    well that is good to know. I'll try and figure out if my false bottom is failing. If it drains quickly, why do people add rice hulls to wheat recipes?

    Force batch sparging with a bike pump

    see attached. Basically, after 1 hour of single step infusion at 154 F, I pour in 170F sparge water and open the valve. I recycle the first gallon or so back into the tun, then I start collecting. It seems to take a very long time. I thought it would take maybe 20 minutes. So I figure...

    Force batch sparging with a bike pump

    I am new to all grain. So far, when my batch sparing slows down to a trickle I have been reaching in with a spoon and mixing up the bed to get it to flow more. I believe this is a mistake causing me to have cloudy beer and lower than desired efficiency. My mash/lauter tun can be sealed. So...

    I think its a stats problem; with each beer have an unknown prior score and each judge having an unknown false positive probability.

    how to? peer review homebrew contest. Calling maths and CS

    independent judges wouldn't work. maybe have a judges contest on the side - which judge most accurately picked the winners (i.e. if you picked the sour pale ale over the eventual winner, you were a poor judge). I am thinking of it in terms of chess scores - chess players are ranked, but I...

    how to? peer review homebrew contest. Calling maths and CS

    Any insight on how to hold a peer reviewed homebrew beer contest? Assume a single category: pale ale. Assume 100 entries (hence 100 judges, so show that it can scale) Obviously, the judges can't each drink 100 beers. How to do it? How to score it? How many beers are required for an...

    How to divert CO2 outside

    http://www.cleanairgardening.com/houseplants.html that page talks about top indoor plants for air quality. I have some vines - they are very resilient. I neglect them for weeks at a time, they just start growing again with some water.

    Do I need head space for a keg?

    Find the CO2 input hole on the inside of the keg and be just below that.

    Wind turbines?!? I was going to hook up an old stationary bike to power it.

    Anyone ever hear of using Peltier effect as a wort chiller?

    bblack - so your saying its possible....(jk) ok, curiosity is still heavily distracting - but I guess its not feasible so I'm just going to forget about it.

    Anyone ever hear of using Peltier effect as a wort chiller?

    if it was running heat to the wort then the electrical connections are backwards.

    Anyone ever hear of using Peltier effect as a wort chiller?

    I dont mean using it to generate electricity-I mean using electricity to drive the heat generation (input watt power) in the atmosphere side and having the wort side cool - ideally using the metal kettle as the cold side - but maybe it would have to be some other metal type. Not really into...

    Anyone ever hear of using Peltier effect as a wort chiller?

    Pretty much the title. I did a quick google and didn't turn anything up. Not really solving a homebrew problem - except maybe saving some water.

    how much steeped grain water in extract brewing?

    Currently, we brew with a 1/2 full kettle and add malt extract and steeped grainw ater to it. What would happen if I steeped the grains in the kettle, then removed them, then added the wort? So instead of ~2quarts of steeped grain water I would have ~2.5 gallons of steeped grain water. I...

    homebrew store with fresh ingredients in Pittsburgh

    I went to South Hills Brewing. I got a deluxe starter kit ($99) for my brother for doing malt extract recipes. Word of warning: No thermometer, no hydrometer flask, no spoon. The lack of thermometer pissed me off the most. Internet only from now on.
