since then they only sell to individual buyers in person at the brewery or the visitors' centre opposite. These methods all go against modern business methods; however, as stated by the Father Abbott on the opening of the new brewery, "We are not brewers. We are monks. We brew beer to be able to afford being monks." Beers The brewery brews three beers: Westvleteren Blonde (green cap), 5.8% ABV, introduced on 10 June 1999. Westvleteren 8 (blue cap) (formerly Extra), 8% ABV. Westvleteren 12 (yellow cap) (formerly Abt), a 10.2% ABV, introduced in 1940. Until 1999, the brewery also produced a 6.2% ABV dark beer and a lighter 4° which served as the monks' table beer, but these were replaced by the Blonde. The 8 and 12 are bottle conditioned and are considered to have a long shelf life, with some drinkers preferring the taste when the beers have been stored for several years. The ingredients are yeast, hops, malt, sugar, caramel and water. The bottles have been sold without labels since 1945. All of the legally required information is printed on the crown tops. Because of this lack of space, Westvleteren beers are the only Trappist beers that do not have the official Trappist logo displayed on the bottle. The logo is only printed on the distinctive wooden crates. Any bottles that are labelled have had them added unofficially by others. For example, some importers into the United States label the bottles in order to comply with local regulations. Availability Buyers were originally limited to ten 24-bottle crates of the beer per car, but as the beer increased in popularity, this was first reduced to five, then to three and now to two or one crates. For the Westvleteren 12 in 2009, it was limited to one case. When making an order now, the type and quantity of beer available for sale are revealed. Sales are limited to one order every 60 days per person per license plate and phone number. Also, the beer must be reserved online through the abbey's website, with registration weeks or even months before the planned pick up date. The online system has replaced the "beerphone" in 2019. The monks do not sell beer to individuals who drive up to the abbey hoping to purchase beer. The reason for this is to eliminate commercial reselling, and hence give all visitors a chance to purchase
