There’s an attitude among some homebrewers that you start off with extract brewing and then, if you’ve got the moxy, you “advance” to all grain brewing.
All-grain brewing definitely has its advantages. The ingredients are less expensive, for one thing, and you can control your final product with a lot more precision. All-grain brewers can modify the chemistry of their mash water, the temperature or stiffness of the mash, or even the style of mash. All these things can help to fine-tune the character of the wort and therefore the flavor of the beer.
But don’t be deceived. There’s a lot you can do with extract. You absolutely do not need to enter the wonderful world of mashing to brew excellent beers!
So recently I’ve been doing some research on “top tips” for extract brewers, and comparing that with my many years of extract batches. Here are the first couple suggestions.
1. Try a full volume boil.
Most extract brewers start off with a relatively small volume of wort — say 2 gallons — and then when the boil is over they pour the wort into a fermentation vessel and add enough cold water to bring the volume up to five and a half gallons. (The extra half gallon allows for any loss when you transfer to secondary, and/or into your bottling bucket.)
There are two big advantages to that method.
- You don’t need to buy a huge pot or a fancy burner, and
- Adding the cold water helps cool the wort after the boil.
But there are also advantages to a full-volume boil.
- You get better hop utilization. Two ounces of hops boiled in two gallons of wort will not produce as much bitterness, flavor or aroma as the very same two ounces of hops boiled in five gallons of wort.
- By boiling all the water, you may avoid possible sources of contamination (in the unlikely event your tap water is infected), and you may drive off unwanted chlorination.
If you have the equipment, give a full-volume boil a try. However, note that your kitchen stove might not have the gumption to give you a good rolling boil with a five-gallon batch. Especially if you have an electric stove. Also, if you do a full-volume boil you really need to do #2 as well.
2. Use a wort chilller.
Rapidly cooling the wort after the boil can dramatically improve your beer.
- The “cold break” you get with rapid cooling can precipitate some unwanted gunk,
- The sooner you cool the wort the less chance you have for hot-side aeration, and
- You lessen the chance of bacterial contamination when you cool the wort quickly.
If you can’t use a wort chiller, immerse your fermenter in a bath of cold water (or even snow, in season). The sooner you chill the wort to fermenting temperatures, the better.
