The other option over bubble wrap...and cheaper, is like the borretmaid. Fruit boxes. They are taped together and covered in packing tape for a durable surface and it holds the heat 'really' well. The custom stainless false bottom was a mission but works well.
The sparge is far from slow by my thinking. As usual nothing to do with the container but the holes in it , your grain bill and your crush.
well it looks like my virgin AG was a 62% success!
Not bad for 2 buckets, some bubble wrap and no tap
I kinda made it up as I went along tho.
My SG is 1.056 but it's 18L.
Do you reckon I should top up to 20L?
I just had a taste from the Hydro tube and it's awsome!
Must be way over 35ibu :unsure:
