Re: Cutting thick stainless (5mm) ?

Stainless can be hardened during manufacture or fabrication - through heat treatment or cold working. The method and amount may differ with the grade but I think it can apply to any of them, certainly it can be done to 304. An example from homebrewing might be some of the thin-walled pots we use, wh...

Re: Cutting thick stainless (5mm) ?

..we've just got an ancient corded drill that doesn't really have a speed control. So I'm just looking at DeWalt or Makita ones at the moment. Yes, i'd suggest getting/borrowing something that'll go slower - in an ideal world with a two (or three) speed gearbox rather than relying entirely on the s...

Re: Cutting thick stainless (5mm) ?

The Q-max punch (and similar) certainly won't do anything near that thickness, and you can't punch half the thickness at once either, so you're right to dismiss it as an option. For DIYing a one-off hole of around 30mm or so, personally I would just drill a circle of smaller holes and then use half-...

Re: used keg cleaning

I would take the spear out and probably also take it apart for this special occasion. Then soak-clean the keg and all the parts with PBW or similar. Thereafter for routine day-to-day cleaning I probably wouldn't disassemble the spear every time, just once in a while. If you connect an old coupler (w...

Re: Dry yeast reuse

Some of the posts above have highlighted a confusion which might explain varying opinions on this general subject. Yeast washing (with acid) and yeast rinsing (with water) are very different things with different degrees of stress for the yeast, but if you try to do research around homebrew forums, ...

Re: Wee Heavy 5 months conditioning in carboys and still fermenting

After this long and with the gravity going nowhere over weeks, it seems safe to say that it has pretty much stopped, the concern (as always) is whether it could potentially start again, which is more of a worry with high FGs. In this case with nearly 70% attenuation and such high OG and alcohol cont...

Re: Wee Heavy 5 months conditioning in carboys and still fermenting

There can be some residual activity, especially in big or difficult beers, but it should really have reached nominal Final Gravity looong ago. Bubbles and airlock activity aren't a good indicator (other things can cause them) so gravity is the best of your measures to trust. You need to check if the...

Re: Tilt hydrometer review

My thanks to PeeBee for the work done so far on the Tilt he's borrowed from me. My disillusionment with the Tilt was mainly down to two problems. It had to be calibrated against a hydrometer or refractometer reading of the final wort every time. It calibrated to 1.000 in water but never matched the...

Re: Dry yeast reuse

There is an old saying that paper never refuses ink so applying that to the modern technology of the day, the internet never refuses comment. With that said I'm looking at reusing a slurry from a dried yeast I will pitch in a Lager. I am reading in some comments that dried yeast does not liked to b...

Re: Tilt hydrometer review

I think you might be wrong there. I'm impartial 'cos Guy has kindly lent me the Tilt and doesn't mind me giving a negative report 'cos he doesn't get on with it. If I'd forked out a quite ludicrous amount of cash for it I might, like many other owners, be more disinclined to have negative thoughts ...

Re: Tilt hydrometer review

I guess if you're the sort of person that takes frequent gravity readings then this would be very useful, but if one just takes a few around the end of fermentation it would seem a bit of an extravagance unless there is a particular need (as of course you may have). Looks like it worked fairly well ...

Re: Extra 2 weeks before bottling

Probably either would work. I'd personally leave it at 18c until your return, with the beer essentially bulk maturing in that time (I'd move to a secondary FV first if the primary FV doesn't seal reasonably well). It should be fairly well progressed by the time you get back. IMO, you might as well d...

Re: Make sure your balls are stainless.

If the seller just said 'stainless steel' and didn't specify the grade or composition, then that allows for quite a range - including lower grades than we would want for brewing. But even so, there are limits (e.g. 10.5% chrome or more); if I'm judging from the photo correctly there might be more da...

Re: Adding sugar post pitching - ABV effect ?

It somewhat depends on how you sparge, but the the reduced amount of sparging liquor (due to the thinner mash) will likely play a part. The minor difference in grain depth arising from a 275 vs 300mm diameter vessel probably won't have much effect, but if you have changed systems then there'll be al...

Re: Adding sugar post pitching - ABV effect ?

Another way of calculating it is that (as this page tells us) 1kg of plain white sugar offers a potential gravity of 370 points in 1L. You require only 3 points extra but in a volume of about 23.5L, so that is roughly (3/370) x 23.5 =0.19kg of sugar (i.e. 190g). Personally i prefer to make adjustmen...
