The specification only says "pliable polymer", but exactly what is it made of? To be more specific I would like to know what temperature it can handle? Is it food grade? If it's food grade, to which temperature is it food grade? Ie can I run boiling hot water through the water path? And then use the water afterwards?

I use a Raspberry Pi with water proof temperature sensors fed in through the airlock to measure the temperature of the wort. They are in contact with the wort from pitch and up to bottling, 4-6 weeks. The website that I buy them from now lists what they are made out of. The ones I use are PVC (Link). They also have another, more expensive, option for PTFE (Link). The links don't specify whether they are food safe, alcohol resistant, …

So I have been dabbling with the use of my sous vide immersion heater for maintaining a perfect mash temperature (it's pretty unbelievable how efficient and accurate these guys are). I have only been doing smaller batches (~3 gallons) up until now. As I have looked to go bigger I have tried to find polycarbonate food bath containers that are large enough, but without much luck. Then it hit me...my MoreBeer Buckets are food grade up to 180 degrees! So, …

I let it soak in hot water solution overnight with LD Carlson Easy Rinse Cleaning Powder (I don't know what the actual ingredients are). I let it soak in StarSan solution overnight also. However, the plastic hose line is still spotty and cloudy. How can I clean the inside of the hose?

Can a 5L plastic bottle be used as fermenter for the first days of fermentation? I'm looking then to transfer the juice to a 2L glass demijohn for the rest of fermentation.

I see some white molds on top of my plastic wine fermenter bucket just in first 3 days old pear wine , my question is that if it is dangerous or not? if not then how can i get rid of those molds?

I have my first brew now in the primary and fermenting away for approaching 48 hours now. I plan to leave it there for 3 weeks rather than risk amateur mistakes for the small benefits secondary offers (if any). But I'm starting to second guess bottling methods that I will use. The brewing kit I bought (the bucket etc. not ingredients) came with 40 PET bottles and lids. I've been reading that while perfectly suitable, they do not lend themselves …

My brew kit came with 750mL plastic (PET) bottles & screw-on caps, which I've used. The "safety seals" are broken, but I thought they were more an indicator of product tampering than a functional device. Am I able to re-use the plastic caps in future brews if I sanitise properly?

I bought this plastic mash paddle for stirring my boiling wort, but now that I'm actually about to use it...I'm wondering if these types of paddles are only safe for things like steeping temperatures. My bort maintains a rolling boil north of 212°F...can I use this paddle to stir it?

I was looking around for some low-cost alternatives to conical fermenters, and I came across inductor tanks. Has anyone used or heard of someone using these tanks? Is there any danger/downside to using them (aside from scratching the inside and risking contamination)? They're made out of medium-density polyethylene, is this the same material "Ale Pails" are made of? For around $55 for a 15 gallon, this seems like a really cheap way to get into making larger batches (as opposed …

I have 15 gallon plastic drums, like what LME comes in. I would really like to use them to age my sours in but I'm concerned with O2 permeability. Has anyone tried this or have any good resources on types of plastic/permeability...

I've been asked to brew for some mates that are heading to a sustainable, no glass, festival and need some advice. The only option I could find that was easy to transport and NOT glass was a 25L water container that has a tap. So...as it won't be sitting around long (4 weeks) do you think I can add the sugar normally needed in bottling straight into the water container, seal the lid and get enough pressure to carbonate or …

I just bought a couple of boxes of plastic bottles for my first home brew. I assume that they are clean being new, but I need to sanatise them. I have a no rinse sanatise solution, should I use that? But do you rinse it after to remove any potential taste? Also I do not have a bottle tree so what happens if there is water in the bottles, or should I wait until 100% dry? Chris

Which synthetic resins are suitable for fabrication of plumbing components e.g pipe sections, metering? I'm trying to find an easy way to mold/house/en-case a custom designed data logger. I'm trying to avoid the complexities of molding HDPE or fibre glass reinforced plastics EDIT: The logger monitors piped water for pressure, temperature & possibly flow rates, implying that . I'd also like to use it outdoors so it would be nice if the housing likes UV rays.

I know that some people say that PVC is fine for racking tubes, but I have someone who is looking for an alternative--HDPE or PP would be acceptable but not preferred. Since PVC is the only type of plastic tube our local hardware store sells, are there some DIY alternatives that have worked well for people? (Caoutchouc? Sheep's intestine? What'd we use for this before plastic came along?)

Just read an article about a NYC beer hall filling 2-liter plastic soda bottles instead of glass growlers. I wouldn't expect this to make a significant difference over 24 hrs, but is there any chance this might affect the flavor? Aside from the risk of skunking by light through the clear container, what about other flavors? While many of us use plastic BetterBottles, they claim to use a special plastic with "No tastes or odors" and "no carry over flavors". …

I've just started homebrewing. The guy at the local homebrew store swears that I don't need any secondary fermentors, that I should just leave my brews in the primary to age and then bottle condition them. I have a plastic bucket fermentor and two 5 gallon PET bottles. I plan to brew some high gravity beers (RIS and an English Barleywine) as well as a dry mead. Since I'm going to be aging a bunch of batches simultaneously I'd rather …

Rather than buying buckets or carboys, I would like to use 5 gallon PET water bottles that I can get free from work (I verified they are PET with the "1" on the bottom). However all my extract recipes are for 5 gallon batches, which would not leave any room for fermentation. Is there any harm in reducing the volume to about 4 gallons for fermentation in these containers? I like higher gravity beers, for what it's worth, but I …

I've read through the various posts here and the common wisdom is that off flavors are because of poor sanitizing or using scratched plastic carboys/buckets. I'd like to read from some of the "master brewers" here and get their take on this commonly held notion. Here is the basis for my question: Palmer's reference has very few off flavors that he mentions as a function of cleaning and none from using scratched fermenters. So, if you know that you are …

What are the Pros and Cons of the different keg types, e.g.: Plastic barrel keg, such as a King Keg Cornelius/Corny Keg? Edit - following the comment from PJ can I clarify that this question is not limited to the 2 keg types above. Please do bring other types and/or variations of keg into the answer.
