1. maybe an extract stout

   I brewed my first biab a few years ago and was so impressed with the quality over extract I never looked back. I have never made an extract dark beer before though (plenty of biab stouts). Does anyone have any thoughts or opinions on brewing an extract stout over AG stout? I thought there might not be a big difference between the two and I could save myself sometime.

   That's one feature of the old direct fire-heated copper kettles, still used at the Caledonian Brewery in Edinburgh. The very hot copper caramelised some of the wort to give a deeper colour, as well as the Maillard tasty stuff. UK breweries tended to use a fair amount of invert sugars in various colours and I'd guess doing your own caramelisation in the kettle would save a few shillings or groats as you wouldn't need to buy as much from the sugar merchants.

2. When to adjust Evap Rate in BIABicus?

   Guys I am only a few brews in but already I am seeing a trend that my boil off rate seems to be a fair bit lower than what BIABicus calculates for me.
   
   Obviously plenty of variables, including weather, location etc. But I am thinking the biggest factor affecting my evaporation rate is the Power input when I am boiling.
   
   I use a 40L electric Urn with a 2.4kw element. I have searched back on the forum when PP was getting data for Boil off rates back in 2010. People were posting evap rates of 3.1...

   Great answer nosco :salute:,
   
   This is an advanced area and one we don't have to worry about too much in the early days. Several things affect attenuation (how much fermentable sugar gets produced in the mash/sparge and then eaten by the yeast) and one of these is mash temperature. So, if you want to brew a Budweiser, if you were doing a single infusion mash, as nosco said you'd aim for a low mash temp of 62 C (143.6F). A stout you might wish to mash at 70C. THese are the two extremes of the...

   Anyone ever use an immersion pre-chiller? With a standard immersion chiller in the summer time I can just barely get the wort down to 80 degrees after about an hour of chilling. I than pour the wort into the fermenter and let it chill in a fridge for a few more hours to get it down to the mid 60's pitching temp. I started using an immersion pre-chiller to help.

    For those who have the ability to crush their own grain a suggestion I'd like to make is conditioning your grain with water before crushing. I have used this for normal batch sparging and full volume mashing and the mash seems to float very well.
    Some claim better efficiency but I got basically the same but the run off was superb due to the way the grain was much more intact. Theoretically with BIAB that could be an advantage.
    Method:
    Get a spray bottle with water and spray the grains in your...

    First post

    As I don't brew BIAB I have a question concerning water/grain ratio. I'm going to brew a Mild but the grain ratio is 9.27lt/kg.
    Have you noticed any detriment to the beer at those ratios? Mash pH, boil pH and/or final beer quality? I will modify my water to the general Mild profile.
    If you are brewing a Mild or similar how do you handle it as a BIAB recipe, final fermenter size about 22 litres. I certainly don't doubt it can be done just open to few guidelines.

Mainly, people seem to be concerned about Beta Amalayse enzymes becoming denatured too quickly at such a high L:G ratio; and leaving you with an overly dextrinous wort.

    Hi. I'm a small batch (3 gallon) BIABer. I've also had good luck fermenting in a corny. After my plate chiller got stuck the other night and then spending an hour cleaning it out, I started thinking about no chill. One downside I'm concerned about (although I guess there are work arounds) is the impact no chill has on flavor and aroma hops.

    Nothing wrong with your idea at all. Chilling in normal cold tap water temperature will be about as good as using an ice bath so don't worry about going to all the hassle of making ice etc. You really only should use ice in a chilling situation when you have chilled your brew close to your cold water tap temperature.
