You will frequently hear homebrewers complain of losing extract efficiency when brewing higher gravity beers. The reason for this is not widely understood in homebrewing circles and not incorporated into recipe formulation software. A loss of extract efficiency at higher original gravities is not inevitable. When it occurs, it is the result of the techniques chosen by the brewer.  It is of particular relevance to brew-in-a-bag (BIAB) brewers, but affects any homebrewer who collects and boils the same amount of wort regardless of the size of his or her grain bill.  In this article, I’ll explain the problem and how to fix it. And tomorrow, I’ll show you one to account for it if you chose not to fix it. [Read more…]

Articles on Brewing Big Beers From Our First Year

birthday-party-suppliesBeer and Wine Journal turned one year old about a month ago. During that time, I’ve posted a couple compilations of articles that ran in our first year, including brewing science stories and articles about all-grain brewing (and, of course, the requisite top 10 list).  Here’s a list of our best articles on brewing strong beers.
