Lid on or off

[Brewery21]

One question is (whilst boiling) commercial plants have enclosed boil kettles with vented/extraction systems on the top lid, where as home brew it seems to be lid off loads of steam filling up the room. I no the condensation is an issue running back in to the wort on enclosed sustems but I've seen the various ways to get round that with collectors of some sort. But what are you guys doing lid on/off/extraction. Cheers

If the boil off goes back into the wort, DMS will build up. I mostly leave my lid off but sometimes I leave it half on, forcing the steam in one direction. I have a spare lid and was thinking I would cut a ten centimeter hole in the top and attach a vent hose to it. But that's for later. Not too worried about it right now.

Lid on
Custom made marine ply lid varnished with yacht varnish then cut in 3/4 and 1/4 pieces with 3 32mm holes cut into the bigger section then standard white pvc drain pipe fittings (3 90 degree elbows and just straight lenghths ) this is fed thru a wall on a slope so the condestation can drain out.
Absolutely zero issues with drip back or veg flavours
Local micro uses similar but with a soil drain pipe and one hole and a water jet to minimise the smell in the out pipe but soil pipe fittings cost more than 32 mm pipe

Lid off; old kitchen extractor hood above the kettle!

If it's just a lid (full cover) then leave it off or make yourself a hood with a vent pipe

Wow foxy that's exactly what I need on my ace system. Used to use boil pot under the cooker hood but obviously the ace can't sit up on worktop now so. Where did you get that from. Or did you make it. And sbond's set up sounds pretty cool too

Made it using a s/steel bowl and a s/steel container got them from a Chinese 'sell just about everything' shop.

Great idea but my new boil kettle is large. Don't think they have a bowl that size. Haha
I like that pipe idea. I might build something like that but with large pipe.

Oh Yeh I see it now very clever. Fits like a glove

You can get bigger pot JB OR even a wok, I have a bigger one on my BM

Lid on. No DMS with Maris Otter. This may not be the case with all malts.

I've never seen a size that big. My boiler takes all 4 hobs. Haha. I have two, one I think is about 100 liters. My second is 170 liters. They're BIG.
But that second one is going to be converted to a FV.

DMS can be hard to detect if you use noble hops that are more grassy.

Reluctantly, mostly with lid on. That's to stop the bleedin' cats from jumping in.
